We have a 4440 and a John Deere 4640 with Quad Range transmissions. Sometimes we have problems entering or exiting the park. What causes this and what is the solution?
If parked on a slope, they tend to get stuck in the park.
Shifting the second lever to 1 or 1R, whichever is opposite to the way the tractor is trying to roll, and CAREFULLY depressing the clutch a little while pulling the lever out of the stop will release it each time.
I THINK it is described in the user manual!
