Mower Deck
Maintenance
Blade Safety
A worn or damaged blade can break, and a piece of
the blade could be thrown toward you or bystanders,
resulting in serious personal injury or death.
•
Inspect the blades periodically for wear or damage.
•
Use care when checking the blades. Wrap the
blades or wear gloves, and use caution when
servicing the blades. Only replace or sharpen the
blades; never straighten or weld them.
•
Always inspect the machine to ensure that the
blades and blade bolts are not worn or damaged.
Replace worn or damaged blades and bolts in sets
to preserve balance.
•
On multi-bladed machines, take care as rotating 1
blade can cause other blades to rotate.
Checking the Mower Blades
1.
Park the machine on a level surface, disengage
the PTO, and engage the parking brake.
2.
Shut off the engine, remove the key, and
disconnect the spark-plug wires from the spark
plugs.
3.
Lift the deck and secure it in raised position as
stated in the
Clean Grass Build-Up Under Deck
(page 42)
section.
4.
Inspect the blades and sharpen or replace as
required.
5.
Reinstall the blades (if they were removed) in
the following order:
A.
Install the bushing through blade with the
bushing flange on bottom (grass) side of
blade.
Figure 29
1. Install bushing in blade prior to installing bushing in spindle.
B.
Install the bushing/blade assembly into the
spindle.
1. Use wrench here for blade installation. This nut has been
torqued to 176 to 217 N∙m (130 to 160 ft-lb)
2. Torque to 68 to 81 N∙m (50 to 60 ft-lb) Apply lubricant
to threads as needed to prevent seizing. Copper-based
anti-seize preferable. Grease acceptable substitute.
C.
Apply lubricant to the threads of the
blade bolt as needed to prevent seizing.
Copper-based anti-seize is preferable.
Grease is an acceptable substitute. Install
the blade bolt finger tight. Place wrench on
the top spindle nut then torque the blade
bolts to 68 to 81 N∙m (50 to 60 ft-lb).
WARNING
Incorrect installation of the blade or
components used to retain the blade can
be dangerous. Failure to use all original
components and assembled as shown
could allow a blade or blade component
to be thrown out from under the deck
resulting in serious personal injury or
death.
Always install the original Toro blades,
blade bushings, and blade bolts as
shown.
Leveling the Mower Deck
Note:
Small adjustments can be accomplished by
increasing the tire pressure in the tire on the low side.
1.
Park the machine on a level surface, disengage
the PTO, and engage the parking brake.

2.
Shut off the engine, remove the key, and
disconnect the spark-plug wires from the spark
plugs.
3.
Check the tire pressure in drive tires and
pneumatic front caster tires (if equipped). Proper
