Fuel filter 2.
Servicing the Cutting Blades 1. Disengage the PTO and move the control levers to the neutral locked position and apply the parking brake. Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3.
Checking for Bent Blades Warning 1. Disengage the PTO and move the control levers to the neutral locked position and apply the parking brake. A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. • Always replace bent or damaged blade with a new blade. • Never file or create sharp notches in the edges or surfaces of blade. 3.
Sharpening the Blades 4. Check the air pressure of all four tires. If needed, adjust to the recommended inflation; refer to Tire Pressure, page 30. 1. Use a file to sharpen the cutting edge at both ends of the blade (Fig. 37). Maintain the original angle. The blade retains its balance if the same amount of material is removed from both cutting edges. 5. Set the height-of-cut at 3 inch (76 mm). 6. Carefully rotate the blade(s) from side to side (Fig. 39).
Adjusting the Front-to-Rear Blade Slope 2 Front 1078 Check the front-to-rear blade level any time you install the mower. If the front of the mower is more than 5/16 inch (7.9 mm) lower than the rear of the mower, adjust the blade level using the following instructions: 1. Position the mower on a flat surface. 2. Disengage the PTO and move the control levers to the neutral locked position and apply the parking brake. 3 1 3.
13. Recheck the side-to-side level of the mower; refer to Leveling the Mower from Side-to-Side, page 32. 1 4 5 3 14. Check the height of the anti-scalp rollers; refer to Adjusting the Anti-Scalp Rollers, page 18. 7 Inspecting the Belts 6 Inspect all belts every 100 hours. Check the belts for cracks, frayed edges, burn marks, or any other damage. Replace damaged belts.
9. Slide the mower out from underneath the tractor. 3. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. Note: Retain all parts for future installation. 4. Lower the height-of-cut lever to the lowest position. Installing the Mower 5. Remove the hairpin cotter and clevis pin from the front trunnion yokes (Fig. 46). 1. Park the machine on a level surface. 2.
Replacing the Grass Deflector 1 Warning 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. 3 2 Never operate the lawn mower unless you install a cover plate, a mulch plate, or a grass chute and catcher. 1. Remove the locknut, bolt, and spring holding the deflector to the mower brackets (Fig. 49). Remove the damaged or worn grass deflector. m–5173 Figure 48 1.
