Operating Instructions

Engine Choke

The choke control lever (black knob) is located on
the left side of the seat. To start a cold engine, move
the choke control forward to the

position. After

engine starts, move the choke control toward the

OFF

position, keeping enough choke to allow the

engine to run smoothly as it warms up. As soon as
possible, move the choke to the

OFF

position. A

warm engine requires little or no choke for starting.

IMPORTANT:

Make sure the choke is in the

OFF

position during normal engine operation; running
with the choke in the

position

CAN

damage the

engine.

Engine Throttle

The throttle control lever (red knob) is located on the
left side of the seat and is used to control engine
speed. Moving the lever

forward

toward the

FAST

position

increases

engine speed; moving it

back-

ward

toward the

IDLE

position

decreases

engine

speed.

Choke and Throttle Location

Forward Speed Control (FSC)

Forward Speed Control (FSC) has two functions:
One is to set forward travel speed, and the other is
to establish the

NEUTRAL-PARK

position. When

the FSC lever is moved into the

FORWARD

posi-

tion, a friction lock holds any forward speed setting
from 0 to 8 mph (0 to 12.9 km/h). The ground speed
is proportional to the lever position; the further the
lever is advanced forward, the faster the tractor
moves. It is not necessary to hold the FSC in posi-
tion since the friction lock maintains the selected
lever position. Pulling back on the steering levers
overrides the FSC setting and slows or stops for-
ward travel. Releasing the steering levers allows
the tractor to resume forward travel at the speed set
by the FSC lever. To stop and park the machine, the
FSC lever is moved backward to the

NEUTRAL-

PARK

position.

Steering Levers

Each drive wheel is controlled by its own indepen-
dent steering lever, for both steering function and

FORWARD/REVERSE

motion. The FSC lever sets

the maximum forward speed, and also sets the for-
ward position of the steering levers. The steering
levers operate

only with a backward pulling

move-

ment of the lever, which causes the drive wheel for
that lever to first slow down, stop, and then reverse
with a full backward lever stroke. The levers are
released to the

FORWARD

position for “straight-

ahead” ground travel.

NOTE:

Pushing forward on the steering levers will

not cause

any

change in tractor motion - there will

be no steering lever reaction and there will be no
machine damage.

Blade Clutch (PTO)

The blade clutch lever is located on the right side of
the seat behind the right fender and is used to en-
gage and disengage the mower blades. The blade
clutch lever has two positions. Pushing the lever

DOWN engages

the PTO that drives the mower

blades. Pulling the lever

UP disengages

the PTO

and engages the blade brake.

Circuit Breaker

One manual reset circuit breaker is located on the
right front of the body. It has a button that pops out
if the circuit breaker trips. The 20 amp circuit break-
er protects the safety and ignition switch circuits.
