hydraulic pump and pushing or towing the machine.
Do not push or tow the machine for more than 1/4
mile (0.4 km).
Important: Do not push or tow the machine
faster than 2-3 MPH (3-4.8 km/h) because internal
transmission damage may occur. The bypass valve
must be open whenever the machine is pushed or
towed.
Important: If the machine must to be pushed or
towed in reverse, the check valve in the four-wheel
drive manifold must also be bypassed. To bypass
the check valve, connect a hose assembly (Hose
Part No. 95-8843, Coupler Fitting No. 95-0985
[Qty. 2], and Hydraulic Fitting No. 340-77 [Qty. 2])
to the reverse traction pressure test port and the
reverse four-wheel drive pressure port.
1. Open hood and remove the center shroud
2. Rotate the bypass valve 90° (1/4 turn) in either
direction to open and allow oil to bypass internally
(Figure 15 ). Because fluid is bypassed, the machine
can be slowly moved without damaging the
transmission. Note the position of the valve when
opening or closing.

3. Close the bypass valve before starting the engine.
However, do not exceed 5-8 ft.-lb. (7-11 N·m)
torque to close the valve.

Operating Characteristics
Practice driving the machine because it has a hydrostatic
transmission and its characteristics are different than
many turf maintenance machines. Some points to
consider when operating the traction unit, cutting
units, or other implements are the transmission, engine
speed, load on the cutting blades or other implement
components, and the importance of the brakes.
To maintain enough power for the traction unit and
implement while operating, regulate the traction pedal
to keep the engine RPM high and somewhat constant.
A good rule to follow is to decrease the ground speed
as the load on the implement increases, and increase
the ground speed as the load decreases.
Therefore, allow the traction pedal to move backward
as the engine RPM decreases, and depress the pedal
slowly as the RPM 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.
Another characteristic to consider is the operation
of the pedals that are connected to the brakes. The
brakes can be used to assist in turning the machine.
However, use them carefully, especially on soft or
wet grass because the turf may be torn accidentally.
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 turn pedal gradually and intermittently until
the uphill wheel stops slipping, thus, increasing traction
on the downhill wheel.
Use extra care when operating the machine on slopes.
Make sure that the seat latch is properly secured and the
seat belt is buckled. Drive slowly and avoid sharp turns
on slopes to prevent roll overs. For steering control,
the cutting unit must be lowered when going downhill.
This product is designed to drive objects into the
ground where they lose energy quickly in grass
areas. However, careless operation, combined
with terrain angle, ricochets, or improperly
positioned safety guard can lead to thrown
object injuries.
•
When a person or pet appears suddenly in or
near the mowing area, stop mowing.
•
Do not resume mowing until the area is
cleared.
Important: Allow engine to idle for 5 minutes
before shutting it off after a full load operation.
