Moving Mower with Stalled Engine
Refer to Figure 2-7
The mower hydro-drives are equipped with bypass valves
for moving the mower when the engine is inoperable. The
valve stems to the bypass valves are located near the top
of the hydraulic pumps and are identified as a hex stud.
Before moving the unit, turn each bypass valve stem
counter clockwise one-half to one revolution and place the
control levers in neutral position.
Do not tow the machine. Move it by hand or use a winch to
load it on a trailer for transporting.
When transporting on another vehicle, the tractor should
be facing forward and it must be secured.

Driving the Mower
!
DANGER!
Never make sudden stops or sudden reversing of direction,
especially when going down a slope. The steering is designed
for sensitive response. Rapid movement of the control levers in
either direction could result in a reaction of the mower that can
cause serious injury.
Steering
Refer to Figure 2-8 on page 12
After starting engine, engage the control levers and steer
as follows:
•
To Go Forward:
Push control levers forward an equal distance.
•
To Go in Reverse:
Pull control levers rearward an equal distance.
•
To Turn Left:
Move the right control lever farther forward from neutral
than the left control lever.
•
To Turn Right:
Move the left control lever farther forward from neutral
than the right control lever.
•
To Pivot Turn:
Move one control lever forward and the other control lever
back of neutral, this will allow the drive wheels to counter-
rotate.
Controlling the Speed
!
WARNING!
In the event of a system failure while mowing, engage both
parking brakes to stop or slow mower. Refer to Figure 2-5.
!
DANGER!
When going in reverse push forward gently on control levers
and avoid sudden movement. Any sudden movement could
cause the front of the mower to come off of the ground resulting
in possible loss of control.
To Stop or decrease speed:
Move control levers to neutral. When going forward pull
back gently on control levers. When going in reverse push
forward gently on control levers.
To Increase Speed:
Increase control levers equal distance from neutral. The
farther forward control levers are from neutral, the faster
the mower will travel forward. The farther back the control
levers are from neutral, the faster the mower will go in
reverse.
IMPORTANT: The engine starter should not be
operated for periods longer then 30 seconds at a time.
An interval of at least two minutes should be allowed
between such cranking periods to protect the starter
from overheating and burn-out.
