Drive System Maintenance Mower Maintenance Checking the Tire Pressure 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. Servicing the Cutting Blades 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.
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. Figure 37 1. Cutting edge 2. Curved area 3. Wear/slot forming • Never file or create sharp notches in the edges or surfaces of blade. Checking for Bent Blades Removing the Blades 1. Raise the height-of-cut lever to the transport position, cutting height position G (also the 4-1/2 inch [115 mm]).
5. Carefully rotate the blade(s) side to side (Figure 42). Measure between the outside cutting edges and the flat surface (Figure 42). If both measurements are not within 3/16 inch (5 mm), an adjustment is required; continue with this procedure. Figure 40 G005278 1. Sharpen at original angle 2. Check the balance of the blade by putting it on a blade balancer (Figure 41). If the blade stays in a horizontal position, the blade is balanced and can be used.
6. Measure from the tip of the front blade to the flat surface and the tip of the rear blade to the flat surface (Figure 44). If the front blade tip is not 1/16-5/16 inch (1.6-7.9 mm) lower than the rear blade tip, adjust the front locknut. 3 4 1 2 3 6 1 2 3 2 5 3 G005074 G005279 Figure 44 1. Blades front to rear 2.
