case/ingersoll 7020, Deere GT235
I have a ingersoll 7020 that has no reverse at rear wheels.I have been reviewing all the forums I could find on this.
I replaced the balljoint,banana plate,most of the drive control linkage that looked worn. With it jacked up,I have forward at rear wheels,
but no reverse.with it in 4wd I only have rear wheel spine in foward and only front wheel spin in reverse. I changed the fluid and filter,everything else
works great,backhoe ,loader ,steering ,so pump pressure shouldnt be a issue.It has 500Hrs.Its a great tractor. Im getting frustrated :confused2:any Ideas ? Thanks

No work done to the diff. Reverse at the rear wheels is a low power,almost none. In 4wd just the fronts work in reverse not in forward. Any problems with control valves ?
