BOLT TORQUE
Mounting bolts and hardware
All hardware used on the 2940 Air Adjust is Grade 5 unless otherwise noted. Grade 5 cap screws are marked with three radial
lines on the head. If hardware must be replaced, be sure to replace it with hardware of equal size, strength and thread type.
Refer to the torque values chart when tightening hardware.
Important: Over tightening hardware can cause as much damage as when under tightening. Tightening hardware
beyond the recommended range can reduce its shock load capacity.
The chart below is a guide for proper torque. Use it unless a specified torque is called out elsewhere in the manual.
Torque is the force you apply to the wrench handle or the cheater bar, times the length of the handle or bar. Use a
torque wrench whenever possible.
The following table shows torque in ft. lbs. for coarse thread hardware.

The Yetter Electric Air Compressor assembly builds 145psi of air pressure and dispenses that air to the row cleaners’ air bags as
the operator commands it from the tractor cab. Yetter electric compressors are durably constructed and designed for easy
integration to operate the Yetter 2940 Air Adjust System. The ability of the air adjustments allows the operator to adjust the row
cleaner precisely on the move without leaving the tractor cab resulting in more acres planted. The precise adjustments give the row
units and planter a more even, smoother ride leading to more accurate seed placement and seed depth resulting in a more uniform
emergence. IT IS NOT RECOMMENDED TO PLUMB ANY OTHER PNUEMATICALLY OPERATED SYSTEMS TO USE THE
2940 YETTER ELECTRIC COMPRESSOR AS ITS AIR SOURCE.
SYSTEM REQUIREMENTS
POWER SUPPLY
The compressor and the VDM (Valve Drive Module) each use 12V from the battery.
The 2940-100 Cab Controller uses a switched power source. The 2940-153 will need connected to a switched power source.
(Connector to the tractor not included)
A CIGARETTE LIGHTER OUTLET ISN’T A SWITCHED POWER SOURCE AND THEREFORE SHOULD NOT BE USED.
SWITCHED POWER SOURCE CONNECTOR PART #’S:
JOHN DEERE P/N: RE67013
CNH P/N:
187103A1
CAT P/N:
AG233356
FUSE PROTECTION
To protect the compressor assembly & VDM from damage always ensure the integrity of the integrated 40 amp and 80 amp circuit
breaker at the tractor battery where cable connects to the battery in case of short or over-circuit. When connected correctly, the
tractor has a fuse to protect the cab controller located in the tractor’s fuse panel. NEVER MOUNT THE COMPRESSOR
ASSEMBLY MORE THAN 50 FEET FROM THE BATTERY USING THE PROVIDED MAIN POWER CABLES. THIS WILL
WEAKEN THE 80AMP BREAKER TO THE POINT OF FAILURE. IF MORE THAN 50 FEET IS NEEDED, BUILD POWER
CABLE(S) TO LENGTH USING 00 GAUGE CABLE!
AIR COMPRESSOR MAINTENANCE
To prolong life expectancy of the compressor, clean the filter on a regular basis by removing the element from the housing, tapping
it on a hard surface, exposed side down. This will empty the pleats of the filter of collected dust. If the dust has been wet or will not
clean out, call Yetter to order a new element, part number 2940-395. You may lightly blow out the interior of the upper housing
using an air tool. The housing and filter should be checked every two days of field operation, or more if conditions are very dusty.
See pages 45 for further maintenance.
CONNECTIONS
FAILURE TO LINE UP TABS WHEN PLUGGING MALE INTO FEMALE CONNECTORS CAN RESULT IN SHORT CIRCUIT.
ALSO CHECK TAB AND SLOT SIZES, PLUGGING CONNECTORS IN BACKWARDS WILL RESULT IN FAULTY SYSTEM!!
2940 AIR ADJUST SYSTEM INFORMATION
The 2940 Air Adjust Residue Manager control system consists of five primary components and kits. These parts include; Residue
Manager (RM) or Residue Manager Coulter Combo Kit, Cab Controller, the Yetter Electric Air Compressor Assembly, Compressor
Mounting Kit and the necessary Wires, Air Lines, and Fittings Kit.
Residue Manager RM/Coulter Combo
Each of these kits will include the required brackets, wheel assemblies, & mounting hardware for installation to the row unit.
Cab Controller
2940-100
RAM Mount
The Cab Controller will use the RAM mount provided for installation in
cab. Hold the POWER button to turn the cab controller on & press
ENTER to activate the system. Make adjustments quickly & accurately
during planting with the cab controller. Adjust up & down pressure to
create the ideal “ride” or floating position for residue managers. Lift &
down pressure settings can be adjusted independently. Down
pressure can be increased to fix row cleaner in the rigid position. Five
presets can be programmed within the controller for quick changes.
Residue Managers can be raised as needed with a push of the
Roman numeral I up button.
Serial Number
There are 2 serial numbers to identify production dates & software.
Cab Controller Serial Number
VDM Serial Number
Air Compressor Assembly
2940 Air Adjust requires a stable air supply source that can provide a
minimum 145psi of clean, dry air. The ‘clean, dry air’ is a key component
of the air supply, moisture within the air supply can shorten the life-cycle
of the system. Another key component is having a leak free system to
reduce the duty cycle and compressor hours, extending the service life.

2940 Air Adjust Installation Guide Outline
STEP 1: RESIDUE MANAGER (RM) OR RM/COULTER COMBO INSTALLATION
Residue Manager Only: Install the RM Assembly using mounting hardware. When installing wheel mount assembly on the adjustment tube of
the RM Assembly, place the top hole of the wheel mount to the 4th or 5th hole from the top of the adjustment tube for conventional tillage or mellow
soils, 5th or 6th hole from the top for no/minimum till conditions. Install wheels on wheel mounts using hardware from the 2966-119 bolt bag. Install
the RM wheels so that the left wheel leads, right wheel trails on the left side of the planter & the right wheel leads, left wheel trails on the right side.
RM/ Coulter Combo: Install the RM/Coulter Combo assembly using hardware from the 2940-128 bolt bag. Mount the coulter blade on the coulter
arm hub & mount the RM wheels using the 5/8 Whiz Lock Nuts. RM wheels on combo units will install in the rear holes on both sides on all rows. It
is recommended to set the coulter blade equal to or above seed depth. Refer to the diagrams on pages 16 - 19
STEP 2: INSTALLING 2940-100 CAB CONTROLLER
Mount the 2940-100 Cab Controller & 2940-113 RAM Mount in the tractor cab. Position the Cab Controller within reach during operation without
compromising safety/visibility from the cab. Connect the 2940-152 harness to the female 6 pin connector on the back of the cab controller & route
the black CAN connector towards the hitch of the tractor. Connect the 2940-153 2 pin connector to the female 2 pin connector on the back cab
controller. Splice the red & black wires to the appropriate connector to fit the tractor’s switched power source. Refer to the diagram on page 20
STEP 3: INSTALLING COMPRESSOR ASSEMBLY & POWER CABLES
COMPRESSOR: Begin by locating a suitable mounting location for the compressor assembly. Placement of the compressor assembly will vary on
the make and model of the planter. Use mounts supplied or depending on application, different mounts may need to be built. NOTE: Be sure to
check clearance of compressor assembly in all locations, especially noting tractor tires during turns, folding/unfolding the planter for transport
mode, markers, and 2-point top link. The compressor must be mounted using 50 feet or less of main power cable extensions from the operating
tractor’s battery. If over 50 feet, heavier gauge power cables (00) must be built or purchased in the correct length.
POWER CABLE: Install the 2940-150 main power cable with 80amp breaker on the battery terminals (red is positive+, black is negative -). Next,
connect the appropriate length of main power extensions (2940-151 or 2940-163) off of the 2940-150, route the main power extensions to large
Anderson power connector coming out of the 2940-101A compressor assembly housing, & install. Install the 2940-181 Y harness on the
compressor. Refer to the diagram on pages 21 & 23
STEP 4: CONTROL BOX AND HARNESS INSTALLATION
CONTROL BOX: Mount the control box in a safe location with mounts/hardware supplied. Install the 2940-415 water separator/regulator assembly
near the control box. Measure & cut the 2940-367 250psi rated 3/8” airline, install airline from outlet elbow on compressor into the 2940-415 inlet
(water trap side). The regulator is preset to only allow 100psi of clean, dry air beyond it. Install 2940-345 3/8” airline from the 2940-415 outlet
(regulator side) to control box inlet. Install ¼” airline from the elbow on the bottom of the 2940-415 to the ¼”PTC fitting closest to the door hinge on
the side of the control box. Route ¼” airline from remaining ¼”PTC fitting on the 2940-103 toward the ground, as airline will dispense moisture.
HARNESS: Install the 2940-166 VDM power cable with 40amp breaker on the battery terminals (red is positive+, black is negative -). Install the
appropriate length VDM power extension (2940-167 or 2940-168) off of the 2940-166, route to the hitch of the tractor to install into the matching
connector on the CAN AUX to Air Harness. Lastly, install the CAN AUX to Air Harness, 2940-164 (5ft) or 2940-165 (10ft). The smaller Anderson
power connector will connect to the VDM power extension, the black CAN connector connects to the other black CAN connector that routes to the
cab controller, & the black male 12 pin Deutsch connector connects to the black female end on the side of the control box housing. 2940-170
(10ft), 2940-171 (30ft), or 2940-430 (20ft) CAN AUX to Air Extensions may be necessary if the control box is mounted further back on the planter
than the hitch. Install the compressor communication harness, 2940-182 or 2940-189 into the 4 pin connector on the control box and route to the
compressor and install into the 2940-181 Y harness. Refer to the diagram on page 22 - 24
STEP 5: DUMP VALVE & DUMP VALVE HARNESS INSTALLATION
Install the dump valves (DV) to the planter as shown in the diagram that matches your planter. 16 row planters and less will have 1 up pressure &
1 down pressure DV on the middle of each wing/side & 1 up pressure & 1 down pressure DV on the wheel track (WT) or center rows. 24 row
planters & larger will have 3 DVs per wing/side; 2 down pressure & 1 up pressure, & 2 DVs on the WT rows, 1 up pressure & 1 down pressure.
Install the gray male 12 pin Deutsch connector of the 2940-162 into the gray female 12 pin Deutsch on the bottom side of the compressor
assembly housing. The 2940-162 will have 4) 2 pin pig tails. The connector labeled RM Up Dump (yellow/black wires) will connect to all up
pressure DVs using 2940-155 (30ft), 2940-157 (15ft), & 2940-160 (5ft) white DV harnesses. Use 2940-159 white Y harnesses to connect all white
DV cables together. The connector labeled RM Down Dump (orange/black wires) will connect to all down pressure DVs using 2940-154 (30ft),
2940-156 (15ft), 2940-161 (5ft) black dump valve harnesses. Use 2940-158 black Y harnesses to connect all black DV cables together.
CONNECTORS LABELED AUX 3 & AUX 4 WILL NOT BE USED! Refer to pages 24 - 36
STEP 6: PLUMBING AIRLINES
A group of airlines that route to the residue manager air bags are referred to as trunk airlines. The airline routing from the RU, RD, & WT to the
inlet of the DV for the matching circuit is referred to as a supply airline. Start by routing the trunk airlines: route black (down pressure) & blue (up
pressure) airline on each wing/side of the planter. If installing on a split row planter, keep the airline on the front rank residue managers on each
wing plumbed separate from the back rank. When plumbing in the WT (wheel track) rows, use the center 4 or 6 rows that plant over the tractor &
planter wheel tracks. If equipping on a narrow transport planter with 4 center rows & 6 rows are desired on the WT circuit, tie in the 1 row on each
wing/side of the planter closest to the first & last center row. Use supplied tees to make enough open ports in each circuit to install supply airline to
the inlet port of each DV of the matching circuit. Also use tees to connect the outlet port of the DVs to the matching circuits of the trunk airlines. On
split row planters, a ball valve will be used to shut air off to bean rows when planting corn. Refer to the diagrams on pages 25 - 37
STEP 7: PERFORM A PRE-OPERATIOIN TEST OF THE SYSTEM
Now that the system is installed, perform a pre-operation test. Start by folding/unfolding & lowering/raising the planter to check for enough slack in
airline & in harnesses at hinge points. Check all electrical connections, cables, & airline making sure nothing was damaged. Next, turn on the cab
controller by holding the power button. After the cab controller is on, turn all pressures (RU, RD, and WT) to 0psi & press ENTER to activate the
system. The compressor will turn on, build to 95psi & turn off. Check the interior of the compressor housing (PQE, Pressure on Valve, & airline
within the housing) for leaks. Apply 30psi to the RU port & watch your row cleaners as they should all rise to maximum up travel. Check for leaks
on all up pressure circuits & fittings. When that leak check is finished, turn RU to 0psi & turn RD & WT to 30. Check all down pressure airline &
fittings in these circuits for leaks & repair as needed. Refer to page 42 - 44

shallower planting depth than 15” blades at the same gauge wheel adjustment setting.
STEP 3: Install each of the RM wheels in the rear D-bolt holes using a 5/8 serrated flange nuts & tighten using a 15/16 wrench.
It is highly recommended to wear gloves & use caution when tightening wheels!
Yetter Cab Controller Installation
(Skip this page if using ISOBUS monitor)
Step 1: Begin installing the 2940 Air Adjust cab controller once an adequate mounting location has been found. Fix the base
component of the 2940-113 Mounting Bracket in place. Use items labeled B if mounting to a slotted, flat mounting system using a
ratchet, 11mm socket, & 11mm wrench to tighten the hardware. Use items C if using a tubular mounting system. 2 different sized U-
bolts are provided for tubular mounting systems. Use a ratchet & 5mm socket to tighten the hardware.
Step 2: Connect the mount bracket to the rear of the controller using 4) M5 Hex Nut and 4) M5 split washers (labeled A) using a
ratchet & 8mm socket to tighten the hardware. Set the cab controller in place and tighten the clamp by turning the handle clockwise.
Step 3: Attach the male 2 pin connector of the 2940-153 to the female 2 pin connector on the 2940-100 Cab Controller. Install the
connector not provided for your tractor at the bare end of the 2940-153 and connect to tractors switched power source. The
cigarette outlet is NOT a switched port on all models of tractors, and therefore should not be used.
Switched Power Source Connector part #’s:
JOHN DEERE PART #: RE67013
CNH PART #: 187103A1
CAT P/N:
AG233356
Step 4: Route & install the 2940-152 hitch to switch
panel wire harness from the rear 6 pin connector of the
2940-100 Cab Controller to the hitch-point at the rear
of the tractor. The black CAN connector of the 2940-152
will connect to the 2940-164 or 2940-165 CAN AUX
to Air Harness. (See page 23 for further details) If an
extension is needed between the 2940-100 Cab Controller
and this harness, a 2940-169 10ft cab to hitch extension is
available to order.
INSTALLING 2940 AIR COMPRESSOR ASSEMBLY
Step 1: Every planter/tractor combination will contain its own unique situations in regard to mounting the 2940
Compressor Assembly for clearance and accessibility. YOU SHOULD EXERCISE YOUR OWN BEST JUDGEMENT TO
FIT YOUR SITUATION. Begin by locating a suitable mounting location for the compressor assembly. Placement of the
compressor assembly will vary on the make and model of the planter. Use mounts supplied or depending on
application different mounts may need to be built. NOTE: Be sure to check clearance of compressor assembly in all
locations, especially noting tractor tires and folding/unfolding the planter for transport mode, markers, and 2-point top link.
Step 2: Visually inspect the proposed mounting location for structural stability and to find signs of wear in that location.
Possible obstructions to be aware of include marker arms, liquid fertilizer tanks, rear tires (duals especially) during tight
turns, 2 point top link, etc…
Step 3: Mark out the position of the Compressor then complete a cycle of folding/unfolding to transport mode and
raising/lowering of the planter; as well as, driving in a tight circle in one or both directions, in planting position, to verify or
identify obstructions.
Step 4: Once the compressor is mounted, repeat the previous process very cautiously to once again verify that the
compressor is clear of obstructions.
Always mount the compressor in the vertical position, housing above the tank.
Refer to pages 60 for Part Identification.
In some situations, mounting brackets may need to be built to fit your planters set-up.
2940-086 – The most common mounting location for larger
planters will be on the draft bar. Use the 2940-086 mounting kit
for situations that require mounting elsewhere on the planter
than the hitch. This will allow the compressor to be elevated &
offset to avoid clearance issues. Different size bolts may be
needed.
2940-085 – Mounting Kit is designed for mounting to
the 2 point cross hitch on the planter, or areas that
require higher elevation for clearance. Different size
bolts may be needed.
2940-090 & 2940-091 – Mounting Kits are designed
to mount the compressor on the main tongue in front
of the bulk fill tanks. 2940-090 is for 8 X 12 frames &
2940-091 is for 8 X 16 frames. These will not work if
fertilizer tanks are mounted in these locations.
2940-103 Control Box Installation
The 2940-103 Control Box is an assembled unit that utilizes compressed air supplied by the OEM hydraulic compressor to operate the
2940 Air Adjust System. In some situations, a mount may need to be built to install the 2940-103 in an adequate location. OEM
ELECTRIC COMPRESSORS ALREADY ONBOARD PLANTERS WILL NOT OPERATE YETTER 2940 AIR ADJUST SYSTEMS!
2940-103 MOUNTING GUIDE
2940-082 (See page 59 for diagram)
2940-083 (See page 59 for diagram)
2940-084 (handrail by compressor)
2940-084 (handrail between bulk fill tanks)
(See page 59 for diagram of the 2940-084)
Water Separator/Regulator Installation
Install the 2940-415 water separator/regulator assembly near the control box in a suitable location out of harm’s way. The water
separator removes moisture from entering the system’s control box. Install the assembly with the water trap vertical & the elbow fitting
towards the ground. The regulator (2940-404) should be set to only allow no more that 100psi into the control box. Below are some
examples of mounting locations for the water separator/regulator assembly.
Airline Routing –Compressor to Control Box
If using a Yetter Electric Compressor
Step 1: Install 2940-367 250psi rated 3/8 airline from the compressor outlet to the inlet port (water trap side labeled A) of the water separator.
Step 2: Install 2940-345 3/8” black airline from the outlet port of the water separator (labeled B) to the inlet port (labeled 1) on the control box.
Step 3: Install ¼” airline from ¼”PTC elbow (labeled C) on water separator to the ¼”PTC fitting (labeled 2) closest to the door hinge on control box.
Step 4: Route ¼” airline from ¼”PTC fitting (labeled 3) on side of control box toward the ground making sure the end of the airline is not pointed
toward anything that moisture may damage or rust.
Compressor Power Cable and Harness Installation
Step 1: Install the 2940-150 main power cable with 80A breaker and the 2940-166 VDM power cable with 40A breaker on the operating tractor’s
battery. Red cable installs on the positive (+) battery terminal post and the black cable installs on the negative (-) battery terminal post.
Step 2: From the open 2 pole Anderson connector of the 2940-150, safely route & install the appropriate length of main power extension cables,
2940-151 is a 10ft main power extension & 2940-163 is a 20ft main power extension, into the Anderson connector that comes out of the bottom of
the compressor housing. If operating tractor is articulating or if compressor is further back on the planter than the hitch, more extension cables may
be needed. Cable length from the battery to the compressor should not exceed 50 feet. Longer than 50 feet distances cause the 80A
breaker to become weak and trip often. If distance is greater than 50 feet, heavier cable needs made using 00 gauge wire.
Step 3: From the open Anderson connector on the 2940-166, safely route/install the appropriate length of VDM power extension cables, 2940-167
(10ft) extension & 2940-168 (20ft) power extension, to the hitch of the tractor. At the hitch of the tractor, place the open 2 pole Anderson connector
next to the black CAN connector that routes to the cab controller, these are the disconnecting points when unhooking the planter from tractor.
Step 4: Install the 2940-164 5ft CAN AUX to Air harness or 2940-165 10ft CAN AUX to Air harness. The black CAN connector connects to the other
black CAN connector that comes from the cab controller. The small Anderson connector connects to the VDM power extension that routes to the
battery. The male black 12 pin Deutsch connector installs into the black female 12 pin Deutsch connector located on the bottom of the compressor
housing. If the compressor assembly is located further back on the planter than the hitch, CAN AUX to Air extension harnessing may need to be
purchased. 2940-170 is 10ft extension, 2940-171 is 30ft extension, & 2940-430 is a 20ft extension.
Electric Communication Harness (Only if application is using the Yetter Electric Compressor)
Step 1: Install the 2940-181 hydraulic compressor solenoid/switch harness; the male 2 pin connector installs into the female connector on the
On/Off solenoid on the hydraulic block on the side of the compressor housing, the female 2 pin connector installs into the male 2 pin connector on
the pressure switch.
Step 2: Connect the 2940-189 10 foot control harness to the 4 pin connector of the 2940-181 & route to control box. If more length is needed, call
Yetter & order more. (2940-182 is 20 foot length; 2940-189 is 10 foot length)
Step 3: Connect the 2940-182 or 2940-189 into the 4 pin female connector on the side of the control box.
2940 -136 Dump Valve Kit Installation
Step 1 - Align the holes on valve (8) with mounting plate (3) holes. Insert bolts (5) through the aligned holes and start the nuts (4)
on the threads. Tighten nut with ¼” wrench while holding bolt with a Phillips screwdriver until tight.
Step 2 - Install supplied 6” piece of airline (6) in port 1, the vent elbow (7).
Step 3 - If install is on a John Deere planter, use flat flanged nut (1) to install Dump Valve assembly by placing circle cut out on mounting tab (3) on
U-bolt used to mount the row unit to planter toolbar. Pinch mounting tab (3) between existing nut on U-bolt & the flat flanged nut (1). If install is on
any other OEM planter, use the serrated flanged nut (2) for the install of the dump valves.
Solenoid Down
Solenoid Up
Single Dump Valve Mounting
Dual Dump Valve Mounting
See pages 26 – 36 for dump valve & dump valve harness installation. Dump valve placement will vary depending on planter size. Dump valve cable
length will vary depending on planter model & row spacing. White dump valve cables are to be used on all lift circuit (blue airline) dump valves.
Black dump valve cables are to be used on all down pressure (black airline) dump valves.
Airline Routing-Planter Frame
Below is a suggested method for safely & securely routing the airlines on the planter frame whether installing trunk airlines (airlines
routing to the row cleaner air bags) or supply airlines (airlines that route from the compressor housing to the dump valve’s inlet port).
Safely route the airlines on the frame that the row units are mounted to or follow the path to which the hydraulic hoses on the planter
are routed. After airline & dump valve harnessing is complete, use provided zip ties to keep parts away from pinch & wear points.
Airline Routing-Row Unit
Below is a suggested method for safely and securely routing the airlines from the air bag to the tees on the planter frame. These
are generalizations and YOU SHOULD USE YOUR OWN BEST JUDGEMENT in routing airlines. DO NOT pass the airlines
between the rear of the parallel arm & the row unit. DO NOT pass airlines between the frame & the head plate used to mount the
row unit to the planter frame. These can act as both a pinch points & wear points. If necessary, use provided zip ties to keep
airlines away from pinch & wear points & sharp or rotating objects that may damage the airline.
Specific airline routing will be dependent upon: Row unit make & model (AGCO, CNH, JD, Kinze, etc), row unit spacing (15”, 20”,
22”, 30”, 36”, etc), parallel arm length, & other variables. RM units will have 1 up pressure & 1 down pressure air bag & RM/Coulter
Combo models will have 2 air bags on the bottom of the bracket for up pressure & a single air bag on top is for down pressure. The
2 up pressure air bags will have airline already tee’d together so the lift pressure trunk airlines will need plumbed to that tee.
Airline Routing
The following pages are dump valve & airline diagrams of different planter models. Dump valve cable length may vary from
the directions given. For example, a 24 row planter on 30 inch centers will have different length dump valve cables than a 24
row planter on 20 inch centers. The wiring & tubing kit will have everything needed to complete the installation.
Direction of flow is: Supply Tank Water Separator Assembly Control Box Dump Valves Air Bags All airlines will be 3/8”.
Blue airline should be used on all lift pressure (smaller) air bags & black airline should be used on all down pressure (larger) air bags.
Use the airline colors to differentiate the lift pressure (Blue Airline) and down pressure (Black Airline) on the planter for
troubleshooting, leak detection, & dump valve circuit indication. Route the airlines as efficiently and conveniently as possible.
If there is no diagram for your situation, contact a Yetter service representative (800-447-5777) & a drawing will be made.

4.
Main Operating Screen (Screen 1, Pictured below): This screen is where the air system is monitored and controlled.
4A
The top of the screen shows what preset you are currently using (1-5), if a manual adjustment is made it will display
“PRESET (X) MANUAL” until the preset is saved, then it will display PRESET X.
4B
This will display “AIR ON” or “AIR OFF” depending on the status of the air system. Pressing ENTER will activate or
deactivate the AIR ON/OFF. “AIR ON” signifies that the air system is operational & supplying air to the attachment. If AIR ON
is displayed with sufficient tank pressure & there is no air in the air bag of the attachment, check the 40A breaker at the
battery.
4C There is a field which will display the tank pressure in psi “TANK PSI”.
4D
There are (4) fields which will indicate “UP” or “DN” (DOWN) depending on the state of the dump valves that are being
controlled. If the Roman Numeral I indicator light is on, UP (under ROW) will be displayed & all residue managers will be in
the up position. The UP/DN function under AUX & Roman Numerals II, III, & IV are not used.
4E
There are (6) fields which define the tools on the system and their pressures. The pressures shown at the bottom of this
screen have two modes. In normal operation mode the real pressure feedback from the air system is shown, but if a manual
adjustment is made it will show the commanded value for 7.5 seconds, after that delay it will return to displaying the feedback
values. Yetter Electric Compressor systems only use RU, RD, & WT.
Operation Settings:
“How much Down/Lift Pressure should I be running?”
The amount of Down/Lift Pressure will vary greatly across soil types, tillage practices, soil moisture, row unit weight & many other
variables. Manage the pressure in the down and/or lift circuits in order to maintain 90%+ Ground Contact while keeping the
pressure between 20-60 psi. The cab controller will display the tank pressure in psi & the down/lift circuits in psi. A typical starting
range for residue managers (RM) would be 35psi up, 30psi down, and 32psi WT. A typical starting range for RM/coulter combo
would be 40psi up, 35 psi down, 37psi WT. When an ideal pressure setting is found for a certain field condition, press & hold a
preset to store the desired setting. If the residue managers aren’t removing enough residue, add more down pressure or subtract
some up pressure. If the residue managers are being too aggressive, subtract down pressure or add up pressure.
Normal operating ranges:
Down Pressure Bags: 20-60psi
Lift Pressure Bags: 20-60psi
Tank Pressure: The tank pressure on the cab controller is the only way to know what the tank pressure is. The compressor will
shut off around 95psi & start to recover around 85psi. The reading from the cab controller comes from the transducer (2940-441)
& relays the psi to the VDM which communicates that pressure to the cab controller. If the tank pressure reads zero & you are
sure there is tank pressure, a transducer needs ordered.
2940 Air Adjust Cab Controller Operation
Main Menu: This screen will allow you to navigate to the setup and service screens. Selecting EXIT will return you to the
main operating screen.
Setup: Currently this screen has one option, to select & edit the Dump Valve Delay.
-
Dump Valve Delay: This screen allows you to adjust the dump valve delay time. Press the ENTER button to go into the edit
mode & then adjust the time with the SCROLL UP/DOWN buttons. The time value will have .25 second resolution & will be
adjustable from 0-60 seconds. Pressing ENTER again will exit the edit mode. Generally, no more than 2.5 seconds is
needed. (see page 44 for proper setting)
-
Setting the Dump Valve Delay:
Ensure all dump valves & harnesses are plugged in securely & that dump valves are functioning properly
Adjustments will be made in increments of .25 seconds.
When the dump valve delay is properly set, the residue managers should react as follows: with sufficient tank pressure, AIR
ON displayed, command RU to 30psi, RD to 35psi, & WT to 37psi. Press the Roman numeral I button & all residue managers
will raise. Press the Roman numeral I button again & all residue managers should drop to half travel & then settle into
position. If the residue managers don’t go to half travel, more dump valve delay is needed. If the residue managers go further
than half travel, less dump valve delay is needed. It is best to have a second person looking as well.
Access the dump valve delay screen on your cab controller.
Adjust the dump valve delay by .25 seconds at a time in the desired direction (more or less), revert to home screen.
Press the Roman numeral I button & observe residue managers to see if more adjustment is needed.

minutes. Evaluate the system for leaks or other issues before continuing. When all issues are fixed, press ENTER to
clear the screen & resume normal operation.
Warning – Check Fault Screens: If a fault is detected, this screen will be displayed. Contact a service representative at
Yetter, & have the fault screens ready, to review voltage readouts for diagnostics. This warning will remain displayed until the
ENTER button is pressed.
Air System On: The state of this displayed text tells the operator if the system is operating or not. The Air System will be ON
if the ENTER button is pressed on the main operating screen (screen 1). At this point the indicator will turn from red to green.
It will maintain ON until ENTER is pressed again, turning the indicator back to its original color. Remember to switch the air
system off, before removing power to the controller. The system is ON when the indicator is green; also the text on the
screen will read “AIR ON” (vs. “AIR OFF”).
Compressor Sump Dump: This dumps any water that has built up in the compressor tank or water separator. This function
is programmed to open the valve for 5 seconds every hour to dump the moisture. The Compressor Sump Dump valve can
also be activated by holding the “Scroll Down” button while on the Main Operating Screen for 8 seconds. The valve will
remain open as long as the button is pressed, releasing the button will close the valve.
2940 Operation Guide
System Start Up Procedure
Below is the 2940 system startup procedure that should be followed every time the 2940-100 Cab Controller is turned on. This will
ensure that component parts of the system are working correctly.
If this is the first start up procedure after installation, make sure to set the dump valve delay and familiarize yourself with cab
controller operation. Before activating the system, save P1 at 35 RU, 30 RD, & 32 WT. Save P2 at 35 RU, 33 RD, & 35 WT.
Step 1: Supply power to the cab controller (start the tractor) & hold the Power button until the cab controller turns on.
Step 2: Turn all pressures (RU, RD, & WT) to 0psi.
Step 3: Press Enter to activate the system. AIR: ON will be displayed. The Yetter compressor will turn on (if it is below 85psi) &
should build to 95psi & shut off. If the Yetter compressor doesn’t run & is below 80psi, check the 40A & 80 amp breaker on the
tractor battery. Trip the breakers and reset the breaker arm firmly back into the pocket.
Step 4: When the compressor has shut off, press a preset (P1 – P5) to apply air to the air bags of the residue managers.
Step 5: Press the UP I button (lowest left button) while watching all the residue managers. When this button is pressed and the
indicator light next to UP is lit, the residue managers should all raise.
Step 6: Press the UP 1 button while watching all the residue managers. All the residue managers should drop to half travel and
then settle into position. (change dump valve delay if necessary, see page 44)
ROW CLEANER DO’S AND DON’TS
1. DO NOT use as a tillage tool; Residue Managers are designed to move crop residue & to break up clods & crust.
2. DO NOT operate planter at slow speeds. Ground speed affects how aggressive the residue manager wheels are. Operate at
sufficient speed (refer to you OEM planter manufacturer manual) to maintain good residue flow.
3. DO NOT expect 100% of crop residue to be cleared, it is not necessary and would necessitate engaging the soil. The width of
path cleared depends on ground conditions, depth setting, and ground speed.
4. DO expect to see wheels occasionally quit turning, indicating ideal (shallow) setting which is not moving soil.
5. DO adjust toolbar frame height 20”-22” and drawbar correctly. It is very important to ensure planter opener will follow ground
contours properly. See Page 43 for the planter levelness and height.
6. DO NOT run air pressure below 20psi or above 60psi. Full range of travel can be achieved between these settings.
7. DO grease the hub cavity of the bearings regularly. Even though the bearings are sealed, filling the hub keeps moisture, dirt, &
debris from entering the hub and ruining the seal. See page 46 for greasing intervals.
8. DO NOT run the coulter, if equipped, deeper than the disc opener blades. Coulter should be set to run even or slightly above
disc opening blades depth.
IMPORTANT: For proper operation, the planter frame must operate level (fore, aft and side to side) and at the correct height,
typically 20”-22”. Regularly inspect the residue manager for loose or worn bolts & hardware. Repair or replace as needed.
Overview:
This electronic control system works with a pneumatic system that controls pressure in the air bags as well as other air valves in the
system on an agricultural application. The air bags provide independent up AND down pressure to the mechanical devices that are
used on an agricultural implement.
System Layout:
There are (2) main parts to the control system. The first being a VDM (Valve Drive Module), the role of the VDM is to provide Outputs
to control functions of the pneumatic system. The VDM will also provide Inputs to monitor the pneumatic system as well as provide
feedback to the operator. The second part is an in-cab switch panel/display (Cab Controller) that allows the operator to control the
pneumatic system and monitor its performance.
Read this before field operation of the Yetter product.
IMPORTANT: Failure to properly set the planter frame height & levelness can result in less than successful operation of the planter &
the Yetter product. This may result in damaged equipment. All operators should read & thoroughly understand the instructions given
prior to using the Yetter product.
NOTE: DO NOT use this product if the planter is not adjusted properly!
Leveling the planter: On a level planting surface, lower the planter frame to an operation height of 20”-22”. Make adjustments to the planter as
necessary. Read the planter operator’s manual for recommended setting. Check to be sure the toolbar & row unit parallel arms are level fore & aft.
Re-Check when the planter is in the field & has been fully loaded with seed, fertilizer, etc. Also, a field check with a bubble level on the frame should
be made of the hitch height to ensure level operation front to back. It is important for the planter to operate level laterally. Tire pressure must be
maintained at pressures specified by the manufacturer. Field & actual planting conditions change & will dictate planter frame heights. You must
ensure that the row unit parallel arms are approximately parallel with the ground.
IMPORTANT: For proper operation of the planter attachments & row units, it is imperative that the planter toolbars and row unit parallel arms be
level side-to-side & front-to-rear. The toolbar frame should operate at a 20”-22” height from the planting surface. Check the manufacturer’s
operator’s manual for instructions on how to adjust the frame height & levelness. The decal below pertains to 2940 coulter combo units!
Pre-Field Operation Guide
SYSTEM LEAK TESTING:
A leak testing procedure should be performed after set-up of the 2940 Air Adjust system is complete. This procedure shall be performed at the
beginning of each planting season and every 20 hours of in season use. In addition, it should be performed if the user notices a lack of air
pressure availability or if the compressor is running an abnormally high duty cycle or run time. It will help keep the duty cycle in check,
thus extending the life of the compressor. The most efficient way to perform a leak test is to use shop air, if available, to allow for a quieter
environment to detect an air leak better. A 2940-382 shop air adaptor is provided in the 2940-174 spare fittings bag. The shop air adaptor is
equipped with a shut off valve. Attach your matching male coupler to the open ¼”NPT & install airline between the 3/8PTC fitting & the water
separator inlet port. Wrap the male threads of the shop air fitting with Teflon tape.
Step 1: Power the cab controller, turn all pressures (RU, RD, and WT) to 0psi, and press ENTER to activate the system. Make sure the Yetter
Electric Compressor has operates correctly, has built around 145psi, & shut off.
Step 2: Check the compressor, water separator assembly, and all compressor housing components for leaks. Start a stopwatch& after 5
Minutes, note the tank pressure. If the tank pressure drops more than 2psi, there is a leak. Repair as needed.
Step 3: Turn up pressure (RU) to 30psi, exit the tractor cab, & start at the compressor housing checking all blue airline on the RU circuit for
leaks. Check all fittings, tees, and dump valves on the RU circuit. Repair leaks as needed & then turn up pressure back to 0psi.
Step 4: Turn down pressure (RD) & wheel track (WT) pressure to 30psi, exit the tractor cab, & start at the compressor housing checking all
black airlines on the RD & WT circuit for leaks. Check all fittings, tees, & dump valves on the RD & WT circuit. Repair leaks as needed.
Step 5: With tank pressure around 145psi, compressor not running, & 0psi commanded in all circuits, note the tank psi. Start a stop watch &
after 5 minutes, note the tank pressure. If tank pressure drops more the 2psi, check for leaks around/inside the compressor housing &
control box. Repair as needed.
Step 6: With tank pressure around 145psi, compressor not running, and 30psi commanded in all circuits, no the tank psi. Start a stop watch &
after 5 minutes, note the tank pressure. If tank pressure drops more the 2psi, check for leaks on the row cleaner fittings, tees, and
dump valves. Repair as needed.
AIR COMPRESSOR PRE-OPERATING TEST PROCEDURE:
Before beginning this test, run the compressor system leak test and ensure it passes. There should be virtually no leaks in the tank circuit before
performing this test. Use a stop watch to time the compressor’s recovery time. Start the time when the tank gauge reaches 85psi & the compressor
turns on. Stop the time when the compressor shuts off at 145psi. If the time is greater than 4 minutes, there is a leak, low battery power, or the
compressor is worn. Repair as needed.
Proper Operation Settings
Dump Valve Delay
To set the dump valve delay, start at the operating screen, press Menu, select Set Up, press Enter to edit, & use the following guide to set to
your planter size:
Non Split Row Planters
6-12 row planters - .5 seconds
16 row planters - .75-1.0 seconds
Split Row Planters
6/11, 6/12, 8/15, or 8/16 planters - .5 – .75 seconds using only corn rows, .75 – 1.5 seconds when using all rows
Note: When the dump valve delay is set properly, the action of the residue managers (RM) will be as follows:
Pressing the Roman numeral I button (up indicator light on) should raise all RMs
Pressing the Roman numeral I button (up indicator light off) will lower RMs to half travel & then settle into position
Air Pressure Settings
Residue Managers Only - A common question is “What pressures should I start out at?” A good starting pressure setting would be 35psi Up
Pressure, 30psi Down Pressure, & 32psi Wheel Track(WT). This particular setting will give each row cleaner a nice sturdy float. If this pressure
setting doesn’t remove enough residue or trenches/digs furrows, adjust the settings accordingly until the row cleaner is doing exactly what you
want it to do. If the row cleaner is trenching, lessen the down pressure or increase the up pressure. If not enough residue is removed, lesson the
up pressure or increase the down pressure. Once a setting is found, hold the desired preset button (P1-P5) until saved. Each field may require a
different setting even though field conditions seem the same. For example, if you use a setting for one no-till field planting corn in soybean
residue, you may find that the setting used for the next field planting corn in soybean residue in no-till conditions may be different. The reason
may be the amount of residue, soil types, moisture amounts, etc.
Residue managers/Coulter Combos - A common question is “What pressures should I start out at?” A good starting pressure setting would be
40psi Up Pressure, 35psi Down Pressure, & 37psi Wheel Track (WT). This particular setting will give each row cleaner a nice sturdy float. If this
pressure setting doesn’t remove enough residue or trenches/digs furrows, adjust the settings accordingly until the row cleaner is doing exactly
what you want it to do. If the row cleaner is trenching, lessen the down pressure or increase the up pressure. If not enough residue is removed,
lesson the up pressure or increase the down pressure. Once a setting is found, hold the desired preset button (P1-P5) until saved. Each field
may require a different setting even though field conditions seem the same. For example, if you use a setting for one no-till field planting corn in
soybean residue, you may find that the setting used for the next field planting corn in soybean residue in no-till conditions may be different. The
reason may be the amount of residue, soil types, moisture amounts, etc.

BEARING ASSEMBLY AND LUBRICATION
Practice Safety
Understand & practice safe service procedures before doing work. Follow ALL the operating, maintenance & safety information in the
equipment operator manual. Clear the area of bystanders, especially small children, when performing any maintenance or adjustments. Keep
work area clean & dry. Use adequate lighting for the job. Use only tools, jacks & hoists of sufficient capacity for the job. Never lubricate,
service, or adjust machine while it is moving. Keep hands, feet, & clothing from power-driven moving & rotating parts. Disengage all power &
operate controls to relieve pressure. Lower equipment to the ground and stop the engine. Remove the key. Wait for all moving parts to stop
before servicing, adjusting, repairing or unplugging. Securely support any machine elements with blocks or safety stands that must be raised
for service work. Keep all parts in good condition and properly installed. Fix damaged equipment immediately. Replace worn or broken parts.
Remove any buildup of grease, oil, or debris. Make sure all guards are in place and properly secured when maintenance work is completed.
Assembly
NOTE: Be certain to align the grease fitting with the slot in the wheel and the hubcap so that the grease can flow freely to the
cavity. The bearing is sealed but the cavity must be filled so that dirt, moisture, & debris do not enter the cavity & ruin the seal.
Grease must fill this hub cap cavity.
Open
Closed
CAUTION: To help prevent serious injury or death to you or others caused by unexpected movement, service machine
on a level surface. Lower machine to ground or sufficiently lock or block raised machine before servicing. If machine is
connected to tractor, engage parking brake & place transmission in "PARK", shut off engine and remove key. If machine
is detached from tractor, block wheels & use shop stands to prevent movement.
CAUTION: Use grease based on NLGI consistency numbers and the expected air temperature range during the service
interval. Use a multi-purpose lithium, water resistant, moderate speed, & NLGI grade #2 grease. Other greases may be
used if they meet the following NLGI Performance Classification: GC-LB.
IMPORTANT: Some types of grease thickener are not compatible with others. Consult your grease supplier before mixing
different types of grease.
