CHECK MOWER BLADES
Service Interval: Before each use or
daily
Stop engine, wait for all moving parts to stop,
and remove key. Engage parking brake.
1. Lift deck and secure in raised position as
stated in the Clean Grass Build-Up Under
Deck section.
2. Inspect blades and sharpen or replace as
required.
3. Reinstall the blades (if they were removed)
in the following order:
A. Install bushing through blade with
flange on bottom (grass) side of blade.
B. Install the bushing and blade onto
spindle.
C. Apply lubricant to threads of blade bolt
as needed to prevent seizing. Copper-
based anti-seize preferable. Grease
acceptable substitute. Install blade bolt
finger tight then torque the blade bolts to
50-60 ft-lb (68-81 N-m).
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 use original equipment, i.e. blades,
blade bushings, and blade bolts as shown.
WARNING
Blades are sharp. Protect your hands
with gloves and/or wrap blades with a
heavy cloth when handling.
CHECK SAFETY INTERLOCK SYSTEM

daily
CAUTION
It is essential that operator safety
mechanisms be connected and in proper
operating condition prior to use.
Do not tamper with the interlock
switch.
Check the operation of the interlock
switches daily and replace any
damaged switches before operating
the machine.
Note:

terrain the seat kill switch has a 1/2 second
delay.
