Disengaged 

Position

Blade Clutch Disengaged

STOPPING THE MACHINE

1.  Pull the steering levers to the 

NEUTRAL-PARK

 

posi tion  and then move the FSC lever backward 
to the 

NEUTRAL-PARK

 position.

2.  Slow the engine to a fast idle; put the throttle in 

the 1/2 throttle position.

3.  Disengage the blade clutch.

IMPORTANT:

   

DO NOT

 disengage the blade 

clutch with high engine speed (above 1/2 throt-
tle) since the brake action on the blade drive will 
cause increased wear of the brake band.

  WARNING

A brake stops the cutter blades (and 
blower on GHS equipped models) from 

freewheeling within five (5) seconds after 

disengaging the clutch.  If the brake sys-
tem malfunctions and the blades do not 

stop  within  five  (5)  seconds,  the  brake 

should be adjusted or repaired before op-
erating the mower.  Contact your Walker 
dealer.

4.  Turn the ignition switch 

OFF.

  When stopping 

the engine, do not reduce the throttle below 1/2 
speed.  Since the engine is equipped with a 
shutdown solenoid, stopping at low idle may 

cause engine run-on or backfiring.

  WARNING

Remove the key from the ignition switch 
when leaving the mower unattended.  This 
will prevent children and inexperienced 
operators from starting the engine.

5.  Engage the parking brake.  Also, engaging the 

parking brake is recommended when stopping 

or parking the machine in a confined space with 

little tolerance for movement.

IMPORTANT:

   The hydrostatic transmissions 

lock to prevent the mower from rolling freely with 
the engine stopped.  However, if the mower is 
parked on a slope, it is necessary to 

ENGAGE

 

the parking 

BRAKE

 to prevent the mower from 

creeping.  This is due to a small amount of slip-
page in the hydrostatic transmissions, especially 

when transmission fluid is warm.

  WARNING

In case the transmission drive belt breaks 
during operation, and if the machine is on 
a slope, the machine will freewheel down 
the slope. To maintain control, immediately 
(1) Release the steering levers and 
simultaneously (2) Move the FSC to the 
NEUTRAL-PARK position.  When the 
machine is stopped or moving slowly, 
engage the parking brake.

NOTE:

   The emergency stop procedure is ex-

actly the same procedure as used to normally 
stop and park the machine.
