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 41). 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 43 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 47 2 1. Opposing blade edge, in position for measuring Figure 45 2. Level surface 3.
