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 blade bolt through blade with washer
on bottom (grass) side of blade.
B. Install blade spacers onto bolt.
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.
CHECK SAFETY INTERLOCK SYSTEM
Service Interval: Before each use or 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
switched.
•
Check the operation of the interlock
switches daily and replace any damaged
switches before operating the machine.
Understanding the Safety Interlock System
The safety interlock system is designed to prevent
the mower blades from rotating by killing the engine
unless:
•
Operator presence is detected when either
motion control lever is moved to the center
operating position.
•
The blade control switch (PTO) is pulled on.
The safety interlock system is designed to kill the
engine if you move or release both control levers
while the PTO switch is in the engage position.
Checking the Safety Interlock System
1. Set control levers to neutral, push PTO switch
to “OFF”, Park Brake to “OFF”.
2. Turn key switch to start, engine should not start.
3.
Set Park Brake to “ON”, pull PTO switch to
“ON”
4. Turn key switch to start, engine should not start.
5.
Push PTO switch to “OFF”, bring left control
lever out of neutral position.
6. Turn key switch to start, engine should not start
7. Return left control lever to neutral, bring right
control lever out of neutral position
8. Turn key switch to start, engine should not start.
9. Return right control lever to neutral position,
turn key switch to start, engine should start.
