Servicing The Cutting Blades - Toro 74255 Operator's Manual

2. Check the distance between the two large
washers, it needs to be 10-1/2 inches (26.7 cm)
(Figure 72).
3. Adjust this distance, by loosening the spring
jam nut and turning the nut in front of each
spring (Figure 72). Turning the nut clockwise
will shorten the spring; counter-clockwise will
lengthen the spring.
4. Lock the nut into position by tightening the
spring jam nut (Figure 72).

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.
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. For convenient
sharpening and replacement, you may want to
keep extra blades on hand.

A worn or damaged blade can break, and a
piece of the blade could be thrown into the
operator's or bystander's area, resulting in
serious personal injury or death.
• Inspect the blade periodically for wear
or damage.
• Replace a worn or damaged blade.
Inspect the blades every 8 hours.
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the
blade control (PTO), and set the parking brake.
Turn the ignition key to Off. Remove the key.
Inspecting the Blades
1. Inspect the cutting edges (Figure 73). If the
edges are not sharp or have nicks, remove and
sharpen the blades. Refer to Sharpening the
Blades.
2. Inspect the blades, especially the curved area
(Figure 73). If you notice any damage, wear,
or a slot forming in this area (Figure 73),
immediately install a new blade.
