The Safety Interlock System

Caution
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
mower from starting unless the control bar is in the neutral
position and to prevent the blades from rotating when the
blade control is released.
Testing the Safety Interlock System
Test the safety interlock system before you use the machine
each time. If the safety system does not operate as
described below, have an Authorized Service Dealer repair
the safety system immediately.
1. Set the machine on a flat, open area.
2. Push the control bar full forward.

3. Rotate the ignition key to the start position and slowly
move the control bar back to neutral. The engine should
not crank until control bar is within 5 degrees of neutral
position.
4. Start the engine; refer to Starting and Stopping the
Engine, page 16. With engine running and control bar in
neutral position, squeeze control bail against control bar
(Do not press deck engagement switch), clutch should
not engage and blades must not rotate.
5. Continue holding the blade control bail and press the
rocker switch forward to on and release. The clutch
should engage and the mower blades begin rotating.
6. Release the blade control bail. The clutch must
disengage and the blades stop rotating.
7. Release the blade control bail (PTO), then push the
blade control switch (PTO) to the on position without
holding the blade control bail. The clutch must not
engage and the blades must not rotate.
8. If all the above conditions are not met have an
Authorized Service Dealer repair the safety system
immediately.

Driving Forward or Backward

The Enhanced T–Bar control system is designed to provide
easy and comfortable operation of the hydrostatic drive.
The control regulates ground speed, as well as forward,
reverse and neutral functions, as well as steering direction.
The throttle control regulates the engine speed as measured
in rpm (revolutions per minute). Place the throttle control in
the fast position for best performance.
Operate the machine with the engine speed set at slow or
medium when learning how to use the controls. Practice
driving the machine in a level open area.
Selecting Ground Speed
1. Place the quick release levers in the unlock position
(Fig. 14).
2. Move the reference bar forward or backward to set the
desired forward speed. The pointer indicates
approximate ground speed (Fig. 14). When the bar is in
the full forward position the ground speed is
approximately 6 mph. When the reference bar is in the
middle position the ground speed is approximately
3 mph.
Note: In normal conditions, a 2.5 to 3.0 mph ground speed
(middle position of the reference bar) is best for cutting
performance. Use a faster ground speed for light cutting or
transport. Use a slower ground speed in heavy cutting
loads.
3. Place the quick release levers in the lock position
(Fig. 14).
