Blade Service (Fig. 7, 8, 9)
The blade must be replaced if a solid object is hit, the
blade is out of balance, worn or bent. Always use
genuine TORO replacement blades to ensure safety
and optimum performance. Never use blades made by
other manufacturers because they could be dangerous.
Do not try to straighten a blade that is bent,
and never weld a broken or cracked blade.
Always use a new TORO blade to assure
continued safety certification of the product.
1 . Raise cutting unit to highest position, shut the engine
off and engage parking brake. Block cutting unit to
prevent it from falling accidentally.
2. Grasp end of blade using a rag or thickly padded
glove. Remove special screw, belleville washer and
blade from spindle assembly.
NOTE: The special screw has left hand thread.
3. To install the blade, assemble parts in reverse order,
and make sure the blade sail is facing up. Tighten
special screw to 75 to 100 ft-lb.
