Measure the right blade at the B location, from a level surface to the cutting edge of the blade tip (Figure 92). 3. Record this measurement.
Adjusting the Compression Spring 1. Raise the mower lift lever to the transport position. 2. Check the distance between the 2 large washers, it needs to be 28.2 cm (11-1/8 inches) for 52 inch mower decks, 26.7 cm (10-1/2 inches) for 60 inch mower decks, or 29.2 cm (11-1/2 inches) for 72 inch mower decks (Figure 95). g001041 Figure 94 1. Measure here from blade to hard surface 2. Measure at A and B 2.
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 Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade.
Sharpening the Blades Note: The difference between the dimensions obtained in steps 4 and 6 must not exceed 3 mm (1/8 inch). 1. Note: If this dimension exceeds 3 mm (1/8 inch), the blade is bent and must be replaced. Use a file to sharpen the cutting edge at both ends of the blade (Figure 99). Note: Maintain the original angle. Note: The blade retains its balance if the same amount of material is removed from both cutting edges.
Installing the Blades 1. Replacing the Grass Deflector Install the blade onto the spindle shaft (Figure 101). Important: The curved part of the blade WARNING must be pointing upward toward the inside of the mower to ensure proper cutting. 2. An uncovered discharge opening could allow the machine to throw objects toward you or bystanders, resulting in serious injury. Also, contact with the blade could occur. Install the spring disk and blade bolt (Figure 101).
Cleaning Cleaning under the Mower Deck Service Interval: Before each use or daily 1. Park the machine on a level surface, disengage the blade-control switch (PTO), and engage the parking brake. 2.
