Adjusting Cutting Height - Walker T27i Operator's Manual

Operating Instructions
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 further opera-
tion of the mower. Contact your Walker
dealer, or refer to Clutch Disengagement/
Brake Action on page 89.
4. Slow the engine to idle, put throttle in IDLE
position; turn the ignition switch OFF.
Remove the key from the ignition switch
when leaving the mower unattended. This
will prevent children and inexperienced op-
erators from starting the engine.
5. Engage the parking brake.
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 trans-
missions, especially when transmission fluid is
warm. Also, engaging the parking brake is
recommended when stopping or parking the
machine in a confined space with little toler-
ance for movement.

WARNING
WARNING
CAUTION
An operator presence switch (seat switch)
will cause the engine to stop if the parking
brake is in the DISENGAGED position and
the operator is not in the seat. The function
of this switch should be checked by the op-
erator raising off the seat with the parking
brake lever in the DISENGAGED position
(tractor not moving and blade clutch disen-
gaged); the engine should stop. NOTE: Al-
low 1/2 second "off the seat" for the time
delay function. If the safety sys tem is not
working, it should be repaired or replaced
before operating the mower. DO NOT dis-
connect the safety switches; they are for
the operator's protection.
WARNING
In case either of the transmission drive
belts break during operation, and if the ma-
chine is on a slope, the machine will free-
wheel 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 ma-
chine is stopped or moving slowly, engage
the parking brake.
NOTE: The emergency stop procedure is
exactly the same procedure as used to nor-
mally stop and park the machine.

ADJUSTING CUTTING HEIGHT

WARNING
The engine must be stopped before adjust-
ing cutting height. Disengage the blade
clutch (PTO), engage the parking brake,
stop the engine, and remove the ignition
key. Wait for all move ment to stop before
getting off the seat.
