Inspecting And Sharpening The Blade - Toro Groundsmaster 200 Series Operator's Manual

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.
Do not try to straighten a blade that is bent.
Never weld a broken or cracked blade.
Replace a worn or damaged blade with a new
Toro blade to ensure continued safety
certification of the product.

3. Install the blade—sail facing toward the cutting
unit—with the anti-scalp cup and blade bolt. Tighten
the blade bolt to 85–110 ft.-lb. (115–149 N m).
Inspecting and Sharpening the
Blade
1. Raise the cutting unit to the highest position, shut the
engine off, and engage the parking brake. Block the
cutting unit to prevent it from accidentally falling.
2. Examine the cutting ends of the blade carefully,
especially where the flat and curved parts of the blade
meet (Fig. 35-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. 35-B), replace the
blade; refer to Removing the Cutting Blade, page 23.

3. Examine the cutting edges of all blades. Sharpen the
cutting edges if they are dull or nicked. Sharpen only
the top side of the cutting edge and maintain the
original cutting angle to ensure sharpness (Fig. 36). The
blade will remain balanced if the same amount of metal
is removed from both cutting edges.
Warning
If the blade is allowed to wear, a slot will form
between the sail and flat part of the blade
(Fig. 35-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.
Replace a worn or damaged blade with a new
Toro blade to ensure continued safety
certification of the product.

4. To check the blade for being straight and parallel, lay
the blade on a level surface and check the ends. The
ends of the blade must be slightly lower than the center,
and the cutting edge must be lower than the heel of the
blade. This blade will produce a good quality of cut and
