switched power circuits will be on.

position. The engine will continue to run.
Using Mower Engagement Switch
• To Engage Mower - Pull mower engagement knob up.
• To Disengage Mower - Push mower engagement knob down.
Using the Hour Meter
• The hour meter shows the number of hours the engine has run. The hour
meter does not accumulate hours with the engine off when the key is in
the run position. Use the hour meter to determine when your machine has
reached the recommended service intervals.
• Turn the key to STOP position when not using the machine.
• Hour meter cannot be reset.
Using the Motion Control Levers
Before using the machine, become familiar with the motion control levers
and how they respond. It is essential to know how the machine
accelerates, steers and stops.
The functions of the motion control levers are:
• Dual function neutral position.
• Steering.
• Acceleration.
• Braking.
Start/shutdown Position
MX37896
• Motion control levers must be in the start/shutdown position (A) and the
park brake locked (B) to start the engine.
• Forward and reverse movement of the motion control levers is prevented
when levers are moved to the start/shutdown position.
• Operator can exit mower with the engine running when the mower
engagement switch is disengaged, the motion control levers are in the
start/shutdown position and the park brake is locked.
• Motion control levers must be in the start/shutdown position to safely
enter and exit the operator seat.
Neutral Position
MX37897
• Machine speed, motion, and direction can be controlled when the engine
is running, motion control levers are in the neutral position (C), and the
park brake is unlocked (D).
• To stop the machine for an emergency, move the motion control levers
quickly back to the neutral position.
Forward and Reverse Travel
Straight forward and reverse travel takes practice. If the machine does not
track in a straight line when going forward or reverse, the motion control
lever tracking may need adjusting.
1. Move throttle lever to the fast position.
2. Unlock park brake.
3. Move both motion control levers from the start/shutdown position inward
to the neutral position.
c
CAUTION: Avoid injury! Learn use of the motion control
levers and practice at half throttle until becoming proficient and
comfortable with the operation of the machine.
Do not move motion control levers from forward to reverse or
reverse to forward position rapidly. Sudden direction changes
could cause loss of control or damage the machine.
