Hi my name is***** will be glad to try to help. There is also a seat belt switch and door switch if you have the enclosed cab option. Check all your fuses and check the seat, seatbelt, and door switch if equipped.
Testing Safety Systems
c CAUTION: Avoid injury! Engine exhaust fumes can cause sickness or death:
· Catalytic mufflers reduce emissions. The effectiveness depends upon engine load and exhaust temperature levels that are not always present in skid steer operations. Catalytic mufflers will not provide fume-free exhaust for confined operations.
· If it is necessary to run an engine in an enclosed area, use an exhaust duct system to remove the fumes.
· Always work in a well ventilated area.
NOTE: If the skid steer is equipped with auxiliary hydraulics be sure the control valve is in neutral. The park brake switch must be engaged before engine will crank.
Use the following checkout procedure to check for normal operation of machine.
If there is a malfunction during one of these procedures, Do not operate machine. See your John Deere dealer for service.
Perform these tests in a clear open area. Keep bystanders away.
Testing Park Brake Switch

2. Sit on operator's seat, buckle seat belt, and disengage park brake switch.
3. Turn the key to the start position.
