The tracks and turret motors seems to be locked on a hydraulic safety. I did notice the hydraulic oil level was low and filled the tank. How do you release the lock. Everything else is operating fine. There is pressure in/out on the motor lines.

I have check the cab and there is no turret lock. There is a lock for all hydraulics which is working. This problem I think must be an internal sensor or hydraulic safety?
