Parking Brake
The parking brake functions by locking a pin into the
hydrostatic transmission pinion gear teeth. Moving
the lever FORWARD engages the parking brake;
moving the lever BACKWARD 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 po-
sition 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 axle drive.
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 release the
pin.
Transmission Lockout Levers
The transmission lockout levers disengage the hy-
drostatic transmissons. By lifting the lever on top of
the transmission and locking it into place with the
lockout cam, the hydrostatic transmissions are re-
leased to permit freewheeling. By releasing the cam
and lowering the lever, the transmissions are en-
gaged for normal operation. The transmission lever
in the LOCKOUT position is used to enable moving
the machine without the engine running (e.g., for ser-
vice). Refer to TRANSMISSION LOCKOUT in this
section for operating instructions.
Lockout Lever Location
NOTE: The transmission plunger on the side of the
transmission case (activated by the LOCKOUT LE-
VER) must be completely released during operation
of the mower, otherwise operation of the transmis-
sion will be erratic.
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.
Oil Pressure Warning Light
The oil pressure warning light indicates that engine
oil pressure is below the safe operating range [below
3 to 5 PSI (21 to 34 kPa)]. This light will come on
when the ignition is turned ON, but should go off after
the engine is started. If the light fails to come on when
the ignition switch is turned ON, it could indicate a
burned out bulb. If the light comes on during engine
operation, stop the engine immediately and correct
the source of the problem before further engine op-
eration.
IMPORTANT: Continued operation of the engine
with an illuminated oil pressure warning light MAY
cause severe engine damage (if a low oil pressure
condition exists).
Circuit Breaker (5 Amp)
A 5-amp, manual-reset circuit breaker is located be-
low the ignition switch. The button pops up if the cir-
cuit breaker trips. This circuit breaker protects the
circuits to the safety switch relays, time delay mod-
ule, and GHS.
Light Switch (For Optional Lights)
Operates headlights (when installed).
