Mower Deck 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. g006530 Figure 52 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 (Figure 54). g009680 Figure 56 1. Opposite blade edge (in position for measuring) g009680 Figure 54 2. Level surface 3. Second measured distance between blade and surface (B) 1. Blade (in position for measuring) 2. Level surface 3. Measured distance between blade and the surface (A) 4. A. Rotate the same blade 180 degrees so that the opposing cutting edge is now in the same position (Figure 55).
3. Repeat this procedure until the blade is balanced. Installing the Blades 1. Install the blade onto the spindle shaft (Figure 57). Important: The curved part of the blade must be pointing upward toward the inside of the mower to ensure proper cutting. g010341 3. Curved washer 4. Blade bolt 3. Torque the blade bolt to 135 to 150 N•m (100 to 110 ft-lb). Ensure that the mower deck is level any time you install the mower deck or when you see an uneven cut on your lawn.
