cutting unit while mowing, regulate traction pedal to
keep engine rpm high and somewhat constant. A
good rule to follow is: decrease ground speed as the
load on the cutting blades increases; and increase
ground speed as the load on the blades decreases.
This allows the engine, working with the transmis-
sion, to sense the proper ground speed while main-
taining the high blade tip speed necessary for good
quality of cut. Therefore, let the traction pedal to
move upward as engine speed decreases, and depress
the pedal slowly as speed increases. By comparison,
when driving from one work area to another—with
no load and cutting unit raised—have the throttle in
the FAST position and depress the traction pedal
slowly but fully to attain maximum ground speed.
CAUTION: This product may exceed noise levels
of 85 dB(A) at the operator position. Ear protectors
are recommended for prolonged exposure to reduce
the potential of permanent hearing damage.
Another characteristic to consider is the operation of
the brakes. The brakes can be used to assist in turn-
ing the machine; however, use them carefully, espe-
cially on soft or wet grass because the turf may be
torn accidentally. The brakes can be used to great
advantage to control the direction of the cutting unit
when trimming along fences or similar objects.
Another benefit of the brakes is to maintain traction.
For example; in some slope conditions, the uphill
wheel slips and loses traction. If this situation
occurs, depress the uphill brake pedal gradually and
intermittently until the uphill wheel stops slipping,
thereby increasing traction on the downhill wheel. If
independent braking is not desired, engage the lever
on the left brake pedal with right pedal. This pro-
vides simultaneous braking at both wheels.
Before stopping the engine, disengage all controls
and move the throttle to SLOW. Moving the throttle
to SLOW reduces high engine speed, noise and
vibration. Turn the ignition key to OFF to stop the
engine.
PUSHING OR TOWING THE
TRACTION UNIT
In an emergency, the traction unit can be pushed or
towed for a very short distance. However, Toro does
not recommend this as standard procedure.
IMPORTANT: Do not push or tow the traction
unit faster than 2 to 3 mph (3.2 to 4.8 Km/hour)
because transmission may be damaged. If the
traction unit must be moved a considerable dis-
tance, transport it on a truck or trailer. Whenever
the traction unit is pushed or towed, the by-pass
valve must be open.
1. Remove the hair pin and pivot the seat platform
forward and locate seat support rod in the detent
notch.
2. Depress and hold the pins located in the center
of the two (2) check valve assemblies in the top
of the transmission (Fig. 11) while pushing or
towing the machine.

1. Transmission check valve bypass pins (2)
3. Start the engine momentarily after repairs are
completed and make sure the pins are in the
fully disengaged (fully up) position.
IMPORTANT: Running the machine with by-
pass valve open will cause the transmission to
overheat.

Operating
Adequate rear weight is necessary to prevent
the rear wheels from leaving the ground. Do
not stop suddenly while cutting unit or imple-
ment is raised. Do not travel down hill with the
cutting unit or implement raised. If the rear
wheels leave the ground, steering is lost.
