before initial operation because it has a hydrostatic
transmission and its characteristics are different than
some turf maintenance machines with which you may
be familiar. Pay attention to the transmission, engine
speed, load on the cutting blades, and the importance
of the brakes.
To maintain enough power for the traction unit and
cutting unit while mowing, regulate the 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 load on the blades decreases. This
lets the engine—working with the transmission—
sense the proper ground speed while maintaining the
high blade speed necessary for good quality of cut.
Therefore, allow 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 the
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 machine produces sound levels in excess of
85dBA at the operator's ear and can cause hearing
loss through extended periods of exposure. Wear
hearing protection when operating this machine.
You can use the brakes to assist in turning the
machine; however, use them carefully, especially 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. The
other benefit of the brakes is to maintain traction. For
example; in some slope conditions, the uphill wheel
may slip and lose traction. If this occurs, depress the
uphill brake pedal gradually and intermittently until
the uphill wheel stops slipping. If you don't want
independent braking, engage the lever on the left
brake pedal with the right pedal. This provides
simultaneous braking at both wheels.
Before stopping the engine, disengage all controls and
move the throttle to SLOW. Moving the throttle to
SLOW reduces 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 you can push or tow the traction
unit 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 3.2 to 4.8 kmh because transmission may
be damaged. If you want to move the traction unit a
considerable distance, transport it on a truck or trailer.
Whenever the traction unit is pushed or towed, by-
pass valve must be open.
1.
Remove the hair pin, pivot the seat platform
forward and locate the 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. 14) while pushing or
towing the machine.
1. Transmission check valve by-pass pins (2)
3.
Start the engine momentarily after completing
repairs and make sure the pins are in the full,
disengaged (fully up) position.
Important
Running the machine with the by-
pass valve open will overheat the transmission.
