Caution
If you leave the key in the ignition switch, someone could accidently start the engine and
seriously injure you or other bystanders.
Remove the key from the ignition and disconnect the wire(s) from the spark plug(s) before you
do any maintenance. Set the wire(s) aside so that it does not accidentally contact the spark
plug(s).
Servicing the Cutting Blades
To ensure a superior quality of cut, keep the blades sharp.
For convenient sharpening and replacement, you may
want to keep extra blades on hand.
Danger
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.
Blades must be replaced if a solid object is hit, if the blade
is out of balance or is bent. To ensure optimum
performance and continued safety conformance of the
machine, use genuine TORO replacement blades.
Replacement blades made by other manufacturers may
result in non-conformance with safety standards.
Important
Always check gearbox output shafts for
straightness after impacting solid objects with blades.
Severe damage could result if gearbox is operated with
bent output shafts
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 and disconnect the spark plug
wire(s) from the spark plug(s).
Inspecting the Blades
1. Inspect the cutting edges (Fig 43). If the edges are not
sharp or have nicks, remove and sharpen the blades.
Refer to Sharpening the Blades on page 33.
2.
Inspect the blades, especially the curved area (Fig. 43).
If you notice any damage, wear, or a slot forming in
this area (item 3 in Fig. 43), immediately install a new
blade.

Checking for Bent Blades
1. Rotate the blades until the ends face forward and
backward (Fig. 44). Measure from a level surface to
the cutting edge tip of the blades (Fig. 44). Note this
dimension.
2.
Rotate the opposite ends of the blades forward.
Measure from a level surface to the cutting edge tip of
the blades at the same position as in step 1 above. The
difference between the dimensions obtained in steps 1
and 2 must not exceed 1/8 inch. If this dimension
