This question has probably been asked before but here goes. Is a Deere auto steer steering motor, the kind that fits beneath the steering wheel compatible with a Trimble 750? I have Trimble easy steer now, with the little wheel that turns the steering wheel and it works OK for me but sometimes that little wheel is in the way. Today someone offered to sell me a used Deere unit that fits under the steering wheel. This is only the steering wheel unit and nothing else. Is this unit compatible with my easy steer 750? Thanks.
