More often in dusty, dirty conditions
Important Refer to your engine operator’s manual for additional maintenance procedures.
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 41). If the edges are not
sharp or have nicks, remove and sharpen the blades.
Refer to Sharpening the Blades on page 31.
2. Inspect the blades, especially the curved area (Fig. 41).
If you notice any damage, wear, or a slot forming in this
area (item 3 in Fig. 41), immediately install a new
blade.

Checking for Bent Blades
1. Rotate the blades until the ends face forward and
backward (Fig. 42). Measure from a level surface to the
cutting edge tip of the blades (Fig. 42). 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 3 mm (1/8 inch). If this dimension exceeds
