Never remove the cap of the fuel tank or ad gasoline while the engine is running or when the engine is hot. • If gasoline is spilled, do not attempt to start the engine but move the mower away from the area of spillage and avoid creating any source of ignition until gasoline vapors have dissipated. • Replace all fuel tank and container caps securely. Preparation • While mowing, always wear substantial footwear and long trousers. Do not operate the equipment when barefoot or wearing open sandals. • Thoroughly inspect the area where the equipment is to be used and remove all stones, sticks, wires, bones and other foreign objects. • Before using, always visually inspect to see that guards, and safety devices, such as deflectors and/or grass catchers, are in place and working correctly. • Before using, always visually inspect to see that the blades, blade bolts and cutter assembly are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance. Starting • Disengage all blade and drive clutches and shift into neutral before starting the engine. • Do not tilt mower when starting the engine or switching on the motor, unless the mower has to be tilted for starting. In this case, do not tilt it more than absolutely necessary and lift only the part, which is away from the operator. • Start the engine or switch on the motor carefully according to instructions and with feet well away from the blade(s) and not in front of the discharge chute. Operation • Never mow while people, especially children, or pets are nearby. • Mow only in daylight or in good artificial light. 4

Avoid operating the lawn mower in wet grass,

where feasible. • Stay alert for holes in the terrain and other hidden hazards. • Never direct discharge of material towards bystanders. • Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times. • Never pick up or carry a lawn mower while the engine is running. • Use extreme caution when reversing or pulling a pedestrian controlled lawn mower towards you. • Walk, never run. • Slopes: – Do not mow excessively steep slopes. – Exercise extreme caution when on slopes. – Mow across the face of slopes, never up and down and exercise extreme caution when changing direction on slopes. – Always be sure of your footing on slopes. • Use low throttle settings when engaging the traction-clutch, especially in high gears. Reduce speed on slopes and in sharp turns to prevent overturning or loss of control. • Stop the blade if the lawn mower has to be tilted for transportation when crossing surfaces other than grass and when transporting the lawn mower to and from the area to be mowed. • Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect. • Stop the engine – whenever you leave the lawn mower. – before refueling. – before removing the grass catcher. – before making height adjustment unless adjustment can be made from the operator’s position. • Stop the engine and disconnect the spark-plug wire or turn off and remove the key. – before clearing blockages or unclogging chute. – before checking, cleaning or working on the lawn mower. – after striking a foreign object, inspect the lawn mower for damage and make repairs before restarting and operating the lawn mower. – if lawn mower starts to vibrate abnormally (check immediately). • Use care when using sulkies, and – use only approved drawbar hitch points. – limit loads to those you can safely control. – do not turn sharply: use care when reversing. – do not carry passengers. • Watch out for traffic when crossing or near roadways. • Before leaving the operator’s position – disengage the power take-off and lower the attachments. – change into neutral and set the parking brake. – stop the engine and remove the key. Maintenance and Storage • Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition. • Do not use pressure cleaning equipment on machine. • Never store the equipment with gasoline in the tank and inside a building where fumes can reach an open flame or spark. • Allow the engine to cool before storing in any enclosure. • To reduce the fire hazard, keep the engine, silencer, battery compartment and gasoline storage are free of grass, leaves, or excessive grease. • Check grass catcher components and the discharge guard frequently and replace with manufacturer’s recommended parts, when necessary. • Replace worn or damaged parts for safety. • Replace faulty silencers. • If the fuel tank has to be drained, do this out-doors. • Do not change the engine governor settings or overspeed the engine. Operating an engine 5

at excessive speed can increase the hazard of

personal injury. • On multibladed lawn mowers, take care as rotating one blade may cause others to rotate. • Be careful during adjustment of the lawn mower to prevent entrapment of the fingers between moving blades and fixed parts of the lawn mower. • To ensure the best performance and safety, purchase only genuine Toro replacement parts and accessories.

Contact your Authorized Service Dealer or Distributor or go to www.Toro.com for a list of all approved attachments and accessories. 12

Note: Determine the left and right sides of the

machine from the normal operating position. Adding Fuel Use unleaded regular gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. Important: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline. In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills. • Never fill the fuel tank inside an enclosed trailer. • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand. • Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by a spark. • Store gasoline in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of gasoline. • Do not operate without entire exhaust system in place and in proper working condition. In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling. • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge. • When practical, remove gas-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground. • If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle. • If a gasoline dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Gasoline is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness. • Avoid prolonged breathing of vapors. • Keep face away from nozzle and gas tank or conditioner opening. • Keep gas away from eyes and skin. Using Stabilizer/Conditioner Use a fuel stabilizer/conditioner in the machine to provide the following benefits: • Keeps gasoline fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained. 13

Cleans the engine while it runs

• Eliminates gum-like varnish buildup in the fuel system, which causes hard starting Important: Do not use fuel additives containing methanol or ethanol. Add the correct amount of gas stabilizer/conditioner to the gas. Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. Filling the Fuel Tank 1. Shut the engine off and set the parking brake. 2. Clean around each fuel tank cap and remove the cap. 3. Add unleaded regular gasoline to both fuel tanks, until the level is 1/4 to 1/2 inch (6 mm to 13 mm) below the bottom of the filler neck. This space in the tank allows gasoline to expand. Do not fill the fuel tanks completely full. 4. Install fuel tank caps securely. 5. Wipe up any gasoline that may have spilled. Checking the Engine Oil Level Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking Oil Level in Engine Maintenance, page 25 Note: Determine the left and right sides of the machine from the normal operating position. Think Safety First Carefully read all the safety instructions and decals in the safety section. Knowing this information could help you or any bystanders avoid injury. The use of protective equipment for eyes, hearing, feet and head is recommended. This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure. Wear hearing protection when operating this machine. Figure 5 1. Warning—wear hearing protection. Using the Parking Brake Stop on level ground, disengage drives, engage parking brake, shut off engine and remove key.

Always remove the ignition key and set the parking brake when leaving the machine unattended, even if just for a few minutes. Transporting Machines Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets or bystanders avoid injury. To transport the machine: 1. If using a trailer, connect it to the towing vehicle and connect the safety chains. 2. If applicable, connect the trailer brakes. 3. Load the machine onto the trailer or truck. 4. Stop the engine, remove the key, set the brake, and close the fuel valve. 5. Use the metal tie down loops on the machine to securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes (Figure 11). Figure 11 1. Traction unit tie down loop Side Discharging or Mulching the Grass This mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death. • Never remove the grass deflector from the mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately. • Never put your hands or feet under the mower. • Never try to clear discharge area or mower blades unless you release the bail and the power take off (PTO) is off. Rotate the ignition key to Off. Also remove the key and pull the wire(s) off the spark plug(s). Adjusting the Height-of-Cut The height-of-cut can be adjusted from 1 to 4-1/2 inch (25 to 114 mm) in 1/4 inch (6 mm) increments. Adjustment is done by relocating four hairpin cotter pins in different hole location and by adding or removing spacers. 18

Note: All height-of-cut pins need at least one

spacer or damage can occur to bushing if none are used. Note: All height-of-cut pins can use two spacers maximum. 1. Select hole in height-of-cut post and number of spacers corresponding to the height-of-cut desired (Figure 12). 2. Using the lift handle, raise side of deck and remove hairpin cotter (Figure 12). 3. Add or remove spacers if needed and then align holes and insert hairpin cotter (Figure 12). Note: Spare height-of-cut spacers may be stored on posts and retained by a hairpin cotter. Important: All four hairpin cotter pins must be in the same hole location and with the correct number of spacers for a level cut. Figure 12 1. Carrier Frame 4. Spacers 2. Hairpin Cotter 5. Front height-of-cut post 3. Back height-of-cut post Adjusting the Anti-Scalp Rollers The anti-scalp rollers need to be adjusted in the proper hole location for each height-of-cut position. There needs to be 3/8 inch (10 mm) minimum clearance above the ground. Note: If the anit-scalp rollers are adjusted too low can cause excess wear of the rollers. 1. After adjusting height-of-cut, check the anti-scalp rollers so that there is a minimum of 3/8 inch (10 mm) clearance above the ground (Figure 13). 2. If adjustment is needed, remove the bolt, washers and nut (Figure 13). 3. Select a hole position so the anti-scalp rollers are a minimum of 3/8 inch (10 mm) off the ground (Figure 13). 4.

Positioning the Flow Bafe

The following figures are only recommendations for use. Adjustments will vary by grass type, moisture content, and height of grass. Note: If the engine power draws down and the mower ground speed is the same, open up the baffle. Position A This is the full rear position (see Figure 17). The suggested use for this position is a follows. • Use for short, light grass mowing conditions. • Use in dry conditions. • For smaller grass clippings. • Propels grass clippings farther away from the mower. Figure 17 Position B Use this position when bagging (Figure 18). Figure 18 Position C This is the full open position. The suggested use for this position is as follows (Figure 19). • Use in tall, dense grass mowing conditions. • Use in wet conditions. • Lowers the engine power consumption. • Allows increased ground speed in heavy conditions. • This position is similar to the benefits of the Toro SFS mower. 21

Using the Mid-Size Weight

• Any rear weight must be removed when a Tru–Track® Sulky is installed. • When a Tru–Track® Sulky is installed front weights are needed. Contact an Authorized Service Dealer for the correct quantity of weights and placement. The front end of the machine can rapidly rise up when the mower is removed. This could cause serious injury to you or bystanders. Support the rear of the machine when removing the mower form the carrier frame. 22

Note: Determine the left and right sides of the machine from the normal operating position.

Remove the spark plugs and the metal washers. Checking the Spark Plugs 1. Look at the center of the spark plugs (Figure 29). If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means that the air cleaner is dirty. 2. If needed, clean the spark plug with a wire brush to remove carbon deposits. Figure 29 1. Center electrode insulator 3. Air gap (not to scale) 2. Side electrode Important: Always replace the spark plugs when it has worn electrodes, an oily film on it, or has cracks in the porcelain. 3. Check the gap between the center and side electrodes (Figure 29). Bend the side electrode (Figure 29) if the gap is not correct. Installing the Spark Plugs 1. Install the spark plugs and the metal washer. Ensure that the air gap is set correctly. 2. Tighten the spark plugs to 16 ft-lb (22 N⋅m). 3. Connect the wires to the spark plugs (Figure 29). Fuel System Maintenance Draining the Fuel Tank In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. • Drain gasoline from the fuel tank when the engine is cold. Do this outdoors in an open area. Wipe up any gasoline that spills. • Never smoke when draining gasoline, and stay away from an open flame or where a spark may ignite the gasoline fumes. 1. Park the machine on a level surface, to assure fuel tank drains completely. Then disengage the power take off (PTO), set the parking brake, and turn the ignition key to off. Remove the key. 2. Close the fuel shut-off valve at the fuel tank (Figure 30). 3. Squeeze the ends of the hose clamp together and slide it up the fuel line away from fuel filter (Figure 30). 4. Pull the fuel line off the fuel filter (Figure 30). Open the fuel shut-off valve and allow the gasoline to drain into a gas can or drain pan. 28

Note: Now is the best time to install a new

fuel filter because the fuel tank is empty. Refer to Replacing the Fuel Filter. 5. Install the fuel line onto the fuel filter. Slide the hose clamp close to the valve to secure the fuel line. Figure 30 1. Fuel shut-off valve 2. Clamp Replacing the Fuel Filter Replace the fuel filter after every 200 operating hours or yearly, whichever occurs first.

Checking the Tire Pressure

Check the pressure at the valve stem after every 50 operating hours or monthly, whichever occurs first (Figure 35). Maintain the air pressure in the rear tires at 12-14 psi (83-97 kPa). Uneven tire pressure can cause an uneven cut. Note: The front tires are semi-pneumatic tires and do not require air pressure maintenance. Figure 35 Replacing the Caster Wheel Fork Bushings The caster wheel forks are mounted in bushings pressed into the top and bottom of the carrier frame mounting pivot tubes. To check the bushings, move the caster forks back and forth and side-to-side. If a caster fork is loose, the bushings are worn and must be replaced. 1. Raise the cutting unit so the caster wheels are off the floor, then support the front of the mower with jack stands. 2. Remove the locking pin and spacer(s) from the top of the caster wheel fork (Figure 36). Figure 36 1. Locking Pin 3. Carrier frame pivot tube 2. Spacers 4. Caster wheel 3. Pull the caster wheel fork out of the mounting tube, leaving the spacer(s) on the bottom of the fork. Remember the location of the spacers on each fork to ensure correct installation, and to maintain a level deck. 4. Insert a pin punch into the mounting tube and carefully drive out the bushings (Figure 37). Clean the inside of the mounting tube. Figure 37 1. Mounting Tube 2. Bushing 5. Grease the inside and outside of the new bushings. Use a hammer and flat plate to 31

carefully drive the bushings into the pivot

tubes. 6. Inspect the caster wheel fork for wear and replace if necessary (Figure 36). 7. Slide the caster wheel fork through the bushings in the mounting tube. Replace the spacer(s) onto the fork and secure with the retaining ring (Figure 36). Important: The inside diameter of the bushings may collapse slightly when installed. If the caster wheel fork does not slide into the new bushings, ream both bushings to an inside diameter of 1.126 inch (29 mm). 8. Grease the fitting on the carrier frame pivot tubes using No. 2 general purpose lithium base or molybdenum base grease. Servicing the Caster Wheel and Bearings The caster wheels rotate on a roller bearing supported by a spanner bushing. If the bearing is kept well lubricated, wear will be minimal. Failure to keep the bearing well lubricated will cause rapid wear. A wobbly caster wheel usually indicates a worn bearing. 1. Remove the locknut and wheel bolt holding the caster wheel to the caster fork (Figure 38). Figure 38 1. Locknut 4. Spanner Bushing 2. Cap 5. Wheel 3. Roller Bearing 6. Bushing 2. Remove one bushing, then pull the spanner bushing and roller bearing out of the wheel hub (Figure 38). 3. Remove the other bushing from the wheel hub and clean any grease and dirt from the wheel hub (Figure 38). 4. Inspect the roller bearing, bushings, spanner bushing and inside of the wheel hub for wear. Replace any defective or worn parts (Figure 38). 5. To assemble, place one bushing into the wheel hub. Grease the roller bearing and spanner bushing and slide them into the wheel hub. Place the second bushing into the wheel hub (Figure 38). 6. Install the caster wheel into the caster fork and secure with the wheel bolt and locknut. Tighten the locknut until the spanner bushing bottoms against the inside of the caster forks (Figure 38). 7. Grease the fitting on the caster wheel. Adjusting the Electric Clutch The clutch is adjustable to ensure proper engagement and proper braking. Check adjustment after every 100 hours of operation. 1. Insert a 0.015–0.021 inch (0.381–0.533 mm) feeler gauge through one inspection slot in the side of the assembly. Make sure it is between the armature and the rotor friction surfaces. 2. Tighten the lock nuts until there is slight binding on the feeler gauge but it can be moved easily within the air gap (Figure 39). 3. Repeat this for the remaining slots. 4. Check each slot again and make slight adjustments until the feeler gauge between the rotor and armature with very slight contact between them. 32

For convenient sharpening and replacement, you may want to keep extra blades on hand. A worn or damaged blade can break, and a piece of the blade could be thrown into the operator’s or bystander’s area, resulting in serious personal injury or death. • Inspect the blades periodically for wear or damage. • Replace a worn or damaged blade. 36

Before Inspecting or Servicing the

Blades Park the machine on a level surface, disengage the blades and set the parking brake. Turn the ignition key to off. Remove the key and disconnect the spark plug wires from the spark plugs. Inspecting the Blades Inspect the blades every 8 hours. 1. Inspect the cutting edges (Figure 46). If the edges are not sharp or have nicks, remove and sharpen the blades. Refer to Sharpening the Blades. Figure 46 1. Cutting Edge 3. Wear/slot forming in curved area 2. Sail 4. Crack in the curved area 2. Inspect the blades, especially the curved area (Figure 46). If you notice any cracks, wear, or a slot forming in this area (item 3 in Figure 46), immediately install a new blade. Checking for Bent Blades 1. Disengage the PTO, move the motion control levers to the neutral locked position and set the parking brake. 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3. Rotate the blades until the ends face forward and backward. Measure from a level surface to the cutting edge, position A, of the blades (Figure 47 ). Note this dimension. Figure 47 4. Rotate the opposite ends of the blades forward. 5. Measure from a level surface to the cutting edge of the blades at the same position as in step 3 above. The difference between the dimensions obtained in steps 3 and 4 must not exceed 1/8 inch (3 mm). If this dimension exceeds 1/8 inch (3 mm), the blade is bent and must be replaced; refer to Removing the Blades and Installing the Blades. A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. • Always replace bent or damaged blade with a new blade. • Never file or create sharp notches in the edges or surfaces of blade. 37

Removing the Blades

Blades must be replaced if a solid object is hit, if the blade is out of balance or is bent. To ensure optimum performance and continued safety conformance of the machine, use genuine Toro replacement blades. Replacement blades made by other manufacturers may result in non-conformance with safety standards. 1. Hold the blade end using a rag or thickly-padded glove. 2. Remove the blade bolt, curved washer, blade stiffener, and blade from the spindle shaft (Figure 48). Figure 48 1. Sail Area of Blade 4. Curved washer 2. Blade 5. Blade Bolt 3. Blade stiffener Sharpening the Blades 1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 49). Maintain the original angle. The blade retains its balance if the same amount of material is removed from both cutting edges. Figure 49 1. Sharpen at original angle 2. Check the balance of the blade by putting it on a blade balancer (Figure 50). If the blade stays in a horizontal position, the blade is balanced and can be used. If the blade is not balanced, file some metal off the end of the sail area only (Figure 46). Repeat this procedure until the blade is balanced. Figure 50 1. Blade 2. Balancer Installing the Blades 1. Install the blade onto the spindle shaft (Figure 48). Important: The sail part of the blade must be pointing upward, toward the inside of the mower to ensure proper cutting (Figure 48). 2. Install the blade, stiffener, curved washer, and blade bolt (Figure 48). 3. Torque the blade bolt to 85-110 ft-lb (115-140 N•m). Correcting the Mower Quality of Cut If one deck blade cuts lower than the other, correct as follows. Note: Tire air pressure is critical in these procedures. Make sure all tires have correct pressure. 1. Disengage the PTO and set the parking brake. 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the 38

operating position. Disconnect the spark plug

wire(s) from the spark plug(s). 3. Adjust the tire pressure in the rear tires to specifications; refer to Drive System Maintenance, page 30 . 4. Check that the blades and spindle shafts are not bent. Refer to Checking for Bent Blades. 5. Set the height-of-cut to the 4 inch (101.6 mm) position. Refer to Adjusting the Height-Of-Cut in Operation, page 13. 6. Perform the steps in the following sections Frame Set Up, Checking Front-to-Rear Pitch, and Checking Side-to-Side Leveling. Frame Set Up Checking the Carrier Frame and Engine Deck Alignment Note: Misalignment can cause excess wear on the PTO drive belt. 1. Disengage the PTO and set the parking brake. 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3. Place a long straight edge on top of the engine deck as shown in Figure 51. 4. At the carrier frame cross channel, measure the height at location A (Figure 51). This measurement must be 1-5/16 inch (33 mm), plus or minus a 1/4 inch (6 mm). 5. If the height at location A is not correct, adjustment is needed. 6. Loosen the carrier frame mounting bolts on both sides of the machine (Figure 51). 7. Align the carrier frame and engine deck to match 1-5/16 inch (33 mm), plus or minus a 1/4 inch (6 mm) at location A (Figure 51). 8. Tighten the carrier frame mounting bolts on both sides of the machine. Figure 51 1. Carrier Frame 4. Location A, 1-5/16 inch (33 mm) ±1/4 inch (6 mm) 2. Top of engine deck 5. Straight edge 3.

If the height at location A and B are not the same, change tire pressure slightly to make them the same. Checking the Carrier Frame Front-to-Rear Pitch The carrier frame must have a pitch between 1/8 inch (3 mm) to 3/8 inch (9 mm) over the length of 24 inches (61 cm) on the carrier frame (Figure 53). 1. Measure out 24 inches (61 cm) on the carrier frame (Figure 53). Figure 53 1. Carrier Frame 4. Height at locations A and B 2. 1/4-3/8 inch (6-10 mm) pitch over 24 inch (61 cm) length 5. Caster Wheel 3. 24 inches (61 cm) 6. Caster spacers 2. Measure carrier frame height at location A (Figure 53). 3. Measure carrier frame height at location B (Figure 53). 4. The height at location A must be a 1/4-3/8 inch (6 mm -10 mm) lower than location B (Figure 53). 5. If the carrier frame is not correct, move caster spacers to make it a 1/4-3/8 inch (6 -10 mm) pitch (Figure 53). Move spacers from top or bottom to make the correct pitch. 6. The tire pressure may also be adjusted slightly to make a 1/4 inch (6 mm) pitch. Checking the Carrier Frame Side-to-Side Height The carrier frame needs to be parallel side-to-side from the ground. 1. Disengage the PTO and set the parking brake. 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3. Adjust the tire pressure in the rear tires to specifications; refer to Drive System Maintenance, page 30 . 4. Measure carrier frame height at location A (Figure 54). 5. Measure carrier frame height at location B (Figure 54). 6. If the carrier frame height is not the same move spacers from top or bottom of caster wheel, to make it level. The tire pressure may also be adjusted slightly to make it level. Figure 54 1. Caster Wheel 4. Same height at locations A and B 2. Carrier Frame 5. Caster spacers 3. Front height-of-cut pins 40

Checking the Mower Deck

Front-to-Rear Pitch 1. Adjust the tire pressure in the rear tires to specifications; refer to Drive System Maintenance, page 30 . 2. Position one blade front-to-rear. Measure at A and B locations from a level surface to the cutting edge of the blade tips (Figure 55). 3. The mower blade should be a 1/4 inch (6 mm) lower in front at A than in the rear at B. Rotate blades and repeat for other blades. If it is not correct, proceed to Changing the Deck Front-to-Rear Pitch. Figure 55 Changing the Mower Deck Front-to-Rear Pitch Changing the front-to-rear pitch is done by adjusting the front height-of-cut posts. 1. To change the front-to-rear pitch, the front height-of-cut posts can be adjusted (Figure 56). Figure 56 1. Caster Wheel 4. Jam nut 2. Carrier Frame 5. Ball joint 3. Front height-of-cut pins 2. To raise the front of the deck, loosen jam nut and rotate the front pin clockwise (Figure 56). 3. To lower the front of the deck, loosen jam nut and rotate the front pin counter clockwise (Figure 56). 4. Position the blades front-to-rear. Check the front-to-rear pitch and adjust if needed. 5. Check the side-to-side leveling of the cutting unit. 6. Tighten the jam nuts (Figure 56). Checking the Mower Deck Side-to-Side Height 1. Adjust the rear tire pressure to specifications; refer to Drive System Maintenance, page 30 . 2. Position the blades side-to-side. Measure at C and D locations from a level surface to the cutting edge of blade tips (Figure 57). 41

3. The difference between measurements C and

D should be no more than 1/4 inch (6 mm). Changing the Mower Deck Side-to-Side Height Changing the side-to-side height is done by adjusting the rear tire pressure and caster spacers. 1. Change the rear tire pressure. Do this to the corresponding side that needs adjustment. 2. Adjust the caster spacer. 3. Recheck the front-to-rear pitch and side to side leveling of the cutting unit. Matching Height of Cut 1. Check the rear tire pressure. 2. Set the height-of-cut to the 4 inch (101.6 mm) position following the height-of-cut decal. 3. With the machine on level surface, position one blade front-to-rear. Measure at A and from level surface to the cutting edge of the blade tips (Figure 58). Figure 58 4. The measurement should be 4 inch (101.6 mm). 5. If it does not measure correctly: A. Adjust the rear tire pressure. B. Adjust the caster fork spacers. C. Adjust the front mower deck support pins. 6. Check the carrier frame front-to-rear pitch. Replacing the Grass Deector An uncovered discharge opening could allow the lawn mower to throw objects in the operator’s or bystander’s direction and result in serious injury. Also, contact with the blade could occur. Never operate the lawn mower unless you install a cover plate, a mulch plate, grass deflector or bagger. 1. Remove the locknut, bolt, spring and spacer holding the deflector to the pivot brackets (Figure 59). Remove damaged or worn grass deflector. 42
