3.
Sit on the seat, start the engine and lower the
cutting unit so the castor wheels just clear the floor.
4.
Remove the height-of-cut pin from the right castor
wheel arm. Insert it and the left height-of-cut pin in
the proper height-of-cut holes in the castor arms and
cutting unit.
BLADE BOLT TORQUE
Check blade bolt torque daily or after blade strikes a solid
object. However, if a solid object causes the blade to be
damaged or bent to a degree it is unusable, replace it; refer
to Removing The Cutting Unit Blade, below.
1.
Raise the cutting units to the transport position,
engage the parking brake, shut off the engine and
remove the key from the ignition switch.
2.
Using a torque wrench and cloth or thickly padded
glove to hold the blade, torque the blade bolts on all
cutting units to 190–224 Nm.
REMOVING THE CUTTING UNIT
BLADE
Replace the blade if a solid object is hit, the blade is out of
balance 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.
1.
Raise cutting unit to transport position, engage
parking brake, shut the engine off and remove key
from ignition.
2.
Using a rag or thickly padded glove, grasp end of
blade. Remove blade bolt, lockwasher, anti-scalp
cup and blade from spindle assembly (Fig. 59).
Do not try to straighten a bent blade. Never weld a broken
or cracked blade. Always use a new TORO blade to assure
continued safety certification of the product.

3.
When re-assembling, make sure the blade sail is
facing up. Torque the blade bolt to 190–224 Nm.
INSPECTING AND SHARPENING
THE BLADE
1.
Raise the cutting units to the transport position,
engage the parking brake, shut off the engine and
remove the key from the ignition switch.
2.
Carefully examine the cutting ends of the blade,
especially where the flat and sail (curved part) meet
(Fig. 60 A). Since sand and abrasive material can
wear the metal connecting the flat and sail portions,
check the blade before using the machine. If any
wear is noticed (Fig. 60 B), replace the blade: refer
to Removing The Cutting Unit Blade above.
