Operating Instructions

Parking Brake
The parking brake functions by locking a detent arm
into the transaxle outer control gear teeth. Moving
the lever BACKWARD engages the parking brake;
moving the lever FORWARD releases the brake.
IMPORTANT: Stop the tractor completely before
engaging the parking brake. The parking brake uses
a positive mechanical lock similar to the PARK posi-
tion on an automotive automatic transmission. If the
tractor is moving when the brake is engaged, it will
result in sudden stoppage and possible internal
damage to the transaxle.
NOTE: If pressure on the parking brake pin (e.g.
parked on a hill) makes it impossible to release the
parking brake with the parking brake lever, move the
mower gently forward or backward to allow the brake
detent to set into the teeth.
Transaxle Lockout Rods
The transaxle lockout rods disengage the transax-
les. By lifting the rods up and locking them into place
with the shoulder on the rod in the chassis notch, the
transaxles are released to permit freewheeling. By
releasing the rods and recessing them back toward
the chassis, the transaxles are engaged for normal
operation. The transaxle rods in the LOCKOUT
position are used to enable moving the machine
without the engine running (e.g., for service). Refer
to TRANSAXLE LOCKOUTS in this section for
operating instructions.
NOTE: The transaxle lockout rods ends should be
completely retracted against the body, otherwise
operation of the transaxle may be erratic.
Hydro Lockout Rod Location
Hourmeter
The hourmeter, which is located on the left front of
the body, displays operating time accumulated
while the ignition switch is in the ON position.
The hourmeter provides maintenance reminders
after certain hours of operation. The hourmeter
screen will start flashing the reminder one hour prior
to the recommended interval and will continue until
one hour after the recommended interval (two
hours). The hourmeter does not have a manual
reset function.
* These intervals reflect the actual time that the
reminder will flash (one hour prior to and one
hour after the recommended interval).
** This reminder is only used one time.
*** In normal operating conditions, oil changes in
100-hour intervals are acceptable. Walker and
the engine manufacturers recommend engine
oil changes every 50 hours in extremely dirty
or dusty conditions or for units with less than
100 hours annual use.
NOTE: The blinking hour glass on the display
means that the meter is operating properly.
