Removing The Cutter Blade; Inspecting And Sharpening The Blade - Toro 30834 Operator's Manual

Removing the Cutter Blade

The blade must be replaced if a solid object is hit, the blade
is out of balance or if the blade is bent. Always use genuine
Toro replacement blades to be sure of safety and optimum
performance. Never use replacement blades made by other
manufacturers because they could be dangerous.
1. Raise cutting deck to highest position, shut the engine
off, and engage the parking brake. Block cutting deck to
prevent it from falling accidentally.
2. Grasp end of blade using a rag or thickly padded glove.
Remove blade bolt, anti-scalp cup, and blade from
spindle shaft (Fig. 13).

3. Install blade, sail facing toward cutting deck, with
anti-scalp cup and blade bolt (Fig. 13). Tighten blade
bolt to 85–110 ft.-lb. (115–149 N⋅m).
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.
• Never weld a broken or cracked blade.
• Always replace a worn or damaged blade.

Inspecting and Sharpening the
Blade
1. Raise cutting deck to highest position, shut the engine
off, and engage the parking brake. Block cutting deck to
prevent it from falling accidentally. On the
Groundsmaster 3500, secure cutting deck service latch.
2. Examine cutting ends of the blade carefully, especially
where the flat and curved parts of the blade meet
(Fig. 14-A). Since sand and abrasive material can wear
away the metal that connects the flat and curved parts of
the blade, check the blade before using the machine. If
wear is noticed (Fig. 14-B), replace the blade; refer to
Removing the Cutter Blade, page 13.
Danger
If the blade is allowed to wear, a slot will form
between the sail and flat part of the blade
(Fig. 14-C). eventually a piece of the blade may
break off and be thrown from under the housing,
possibly resulting in serious injury to yourself or
bystanders.
• Inspect the blade periodically for wear or
damage.
• Always replace a worn or damaged blade.

3. Inspect cutting edges of all blades. Sharpen the cutting
edges if they are dull or nicked. Sharpen only the top of
the cutting edge and maintain the original cutting angle
to make sure of sharpness (Fig. 15). The blade will
remain balanced if same amount of metal is removed
from both cutting edges.
