1. Upper frame
2. Clevis pins
3. Carefully lower the frame downward until it rests
on the stops.
4. Insert the clevis pins in the lower holes and
secure them with the snap pins to support the
upper frame in its lowered position.
5. To raise the frame, follow these instructions in
reverse order.
WARNING
The ROPS protection system may not be
effective if the ROPS retaining bolt assemblies
are loose, which may cause serious injury or
even death in the event of a rollover.
When in the raised position, both retaining
bolt assemblies must be installed and fully
tightened to ensure full ROPS protection.
WARNING
When lowering and raising the roll bar, fingers
may get pinched between the machine and
the roll bar.
Use caution when lowering and raising the
roll bar to prevent entrapment of fingers
between the fixed part and the pivot part of
the structure.

Checking the Interlock
Switches
Service Interval: Before each use or daily
CAUTION
g200378
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.
The machine has interlock switches in the electrical
system. These switches are designed to shut off the
engine when you rise from the seat while pressing the
traction pedal. However, you may rise from the seat
while the engine is running and the traction pedal is in
neutral. Although the engine continues to run if you
disengage the PTO switch and release the traction
pedal, shut off the engine before rising from the seat.
To check the operation of the interlock switches, do
the following steps:
1. Drive the machine slowly to a large, relatively
open area.
2. Lower the cutting units, shut off the engine, and
engage the parking brake.
3. Sit on the seat and press the traction pedal.
4. Try to start the engine.
Note:
The engine should not crank. If the
engine cranks, there is a malfunction in the
interlock system; correct it before operating the
machine.
5. Sit on the seat and start the engine.
6. Rise from the seat and move the PTO switch
to the On position.
