Using the Grass Deflector 7. Install the cotter pins to secure the assembly. Note: Repeat the previous steps to the remaining roller. DANGER Without the grass deflector mounted in place, you and others are exposed to blade contact and thrown debris. Contact with the rotating mower blade(s) and thrown debris can cause injury or death Checking the Gearbox Lubricant • Never remove the grass deflector from the mower because the grass deflector routes material down toward the turf.
Maintenance Important: The fasteners on the covers of this machine are designed to remain on the cover after removal. Loosen all of the fasteners on each cover a few turns so that the cover is loose but still attached, then go back and loosen them until the cover comes free. This can prevent you from accidentally stripping the bolts free of the retainers.
level is between the marks. You may use SAE 80-90 weight synthetic gear lube as an alternative. Removing the Mower Deck 1. Move the machine onto a level surface, engage the parking brake, lower the mower deck, shut off the engine, and remove the ignition key. 2. Remove and set aside the hardware securing the PTO guard to the gearbox and slide the guard out of the way (Figure 22). 3. Remove and set aside the 2 bolts, locknuts, and roll pin securing the end yolk to the gearbox shaft (Figure 32). Figure 33 1.
Servicing the Caster Arms The caster arms have bushings pressed into the top and bottom portion of the tube. Wear can occur over time. Check the wear of the bushings by moving the castor fork side to side. Replace both of the bushings if the castor fork has side to side movement. 1. Raise the mower deck so that the wheels are off the ground and block it so that it cannot accidentally fall. 2. Remove the caster assembly from the carrier frame (Figure 11). 3.
Removing the Cutting Blade The blade must be replaced if it hit a solid object, if it is out-of-balance, worn, or bent. Always use genuine Toro replacement blades to ensure safety and optimum performance. Never use blades made by other manufacturers because they could be dangerous. DANGER A worn or damaged blade can break, and a piece of the blade could be thrown at you or bystanders, resulting in serious personal injury or death. • Inspect the blade periodically for wear or damage.
Inspecting and Sharpening the Blade WARNING If the blade is allowed to wear, a slot can form between the sail and flat part of the blade (Figure 40). Eventually, a piece of the blade may break off and be thrown from under the housing, possibly resulting in serious injury to you or bystanders. • Inspect the blade periodically for wear or damage. • Replace a worn or damaged blade with a new Toro blade to ensure continued safety certification of the product.
add shims between the spindle housing and bottom of the mower deck. 1 5. Ensure that the front height-of-cut pins are resting properly on the frame cushions. If the pins are not resting properly, place a shim or shims under the cushion to raise it for proper alignment. 2 6. Position all 3 blades in the A position (Figure 42) and measure from the level surface to the bottom of the tip end of each blade (Figure 43). B B B A A C A C C G010553 Figure 44 G010556 1.

the carriage bolts must be on the inside of the mower deck. Figure 46 1. Idler plate 2. Nut Figure 45 1. Bolt 2. Locknuts 3. Idler adjustment 3. Pivot brackets 4. Spring 5. Hold the torque against the belt and tighten the 2 nuts so that the idler plate is held securely in place. Release the idler adjusting nut. 5. Position the deflector mounts on the pivot brackets and secure the parts together with the bolts, locknuts, and springs. Both locknuts must face each other.
Replacing the Drive Belt The blade drive belt, tensioned by the adjustable idler, is very durable. However, after many hours of use, the belt shows signs of wear. Signs of a worn belt are: squealing when belt is rotating, blades slipping when cutting grass, frayed edges, burn marks, and cracks. Replace the belt if any of these conditions are evident. 1.
Troubleshooting Problem The mower deck not cut or cuts poorly. Possible Cause Corrective Action 1. The blades are dull. 1. Sharpen the blades. 2. One or more blades are bent or damaged. 3. The spindle bolts are loose. 2. Replace the blades. 4. The mower deck belts are loose or broken. 5. The gearbox pulley is loose. 6. A gearbox shaft is broken. 7. The PTO belt is broken. 8. The PTO pulley is loose or broken. 9. The PTO shaft is broken. 10. The pulley on the engine output shaft is loose or broken.
