Servicing Cutter Blade - Toro Wheel Horse 8-25 Operator's Manual

Maintenance

Servicing Cutter Blade

1. Shut off engine and remove wire from spark
plug. Remove ignition key.
IMPORTANT: To remove blade from spindle
shaft, the rider must be tipped on its rear end.
Before the rider is tipped, drain all gasoline
from fuel tank and oil from crankcase. Also
remove battery so acid does not spill onto the
rider. (ALL BAGGING ATTACHMENTS
MUST BE REMOVED BEFORE TIPPING
RIDER.)
2. Drain gasoline from fuel tank: refer to Draining
Gasoline From Fuel Tank, page 34.
3. Drain oil from crankcase: refer to Changing
Crankcase Oil, steps 1-6, page 29.
4. Remove battery from chassis: refer to Removing
the Battery, page 34
5. Shift transmission into 1st gear and engage
parking brake. Tip rider onto its rear end.
6. Grasp end of blade using a rag or thickly padded
glove; then remove blade bolt, washer and blade
(Fig. 16).
Note: Since blade bolt is tightened to 45-60
ft-lb (61-81 Nm) at the factory, it may
be difficult to remove. If the bolt
cannot be removed, contact an
Authorized TORO Service Dealer or a
"service station" for assistance.
7. Using a file, sharpen cutting edge at both ends of
the blade (Fig. 17).
IMPORTANT: Sharpen top side of the blade
and maintain original cutting angle to ensure
a sharp cutting edge. The blade will remain
balanced if same amount of material is
removed from both cutting edges.

8. Check balance of blade by putting it on a blade
balancer. (An inexpensive balancer can be
purchased at a hardware store.) A balanced
blade will stay in a horizontal position on the
balancer. By contrast, a blade that is not
balanced will settle to the heavy side. If blade is
not balanced, file more material off cutting edge
of the blade. Continue to file and check the
blade until it is balanced.
