Hi Dan, My name is***** is your serial number? Also have you lost all travel and steering in all gear positions?

check the oil level and condition as well as your filters for signs of metal/debris indicating internal mechanical problems. If clean then testing your pressures will be the next step. Let me know

Serial number *CAL005333*I have lost all travel and steering in all gear positionsit appears to be electrical to me!
Mechanic: Dan, Technician replied 6 years ago

Thanks for the info. Cut open the hydrostatic drive filters with a non abrasive filter cutting tool or equivalent to check for fine metal. If clean then check and verify the pump drive coupling between the engine and pumps has not failed.

Are you getting any warning indicators?

There is just a green light that shows on the instrumet panel that looks like gear.I talked to a friend and he said it sounds like a sensor.I'm signing off for now. It is late.
Mechanic: Dan, Technician replied 6 years ago

This model has a common failure of the joystick control usually throwing fault codes 4532 and 4531 if the harness checks ok..... Let me know what codes you are getting. i am off for the night myself.... we can follow up as needed.
