I was reading through the service manual for the 140 (30,000 and up) got to the section on power train and so I went out to look over my tractor and make sure I could find everything and I certainly cannot find the throwout arm and bearing.
I've searched here and on WFM and cannot find anything definitive. Did JD get rid of the engine disconnect on the later model 140's? Any body know why?
I'd say your right my 1974 only has the return to neutral feature which is fine I use it as a speed control often so I only need to advance the hand control in either direction and use the pedal to slow and stop.
