Drive System Maintenance 2. Rotate the shaft forward to release the brake. Checking the Tire Pressure Service Interval: Every 25 hours—Check tire pressure. Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut. Check the pressure at the valve stem (Figure 42). Check the tires when they are cold to get the most accurate pressure reading. Refer to the maximum pressure suggested by the tire manufacturer on the sidewall of the caster wheel tires.
Mower Maintenance Servicing the Cutting Blades 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. Figure 44 Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary.
3. Measure from the tip of the blade to the flat surface here. 1 1 G014973 3 2 G014973 3 Figure 48 2 1. Opposing blade edge, in position for measuring Figure 46 2. Level surface 3.

Measured distance between blade and surface (A) WARNING A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. 4.
Leveling the Mower Deck Check to ensure the mower deck is level any time you install the mower or when you see an uneven cut on your lawn. The mower deck must be checked for bent blades prior to leveling; any bent blades must be removed and replaced. Refer to the Checking for Bent Blades procedure before continuing. The mower deck must be leveled side-to-side first then the front to rear slope can be adjusted. Figure 49 Requirements: • The machine must be on a level surface.
Note: Avoid placing the supports under any anti-scalp rollers if present on the deck. Use the notches on the welded bracket to measure the amount of adjustment. Each notch surface is equivalent to 0.25 inch, while a single side is 0.125 inch (Figure 55). Adjust the height of the mower deck to the desired height. 7. Move to the left side of the machine. Check if the side carriage bolt is in the fixed or slotted position (Figure 53). 8.
