I have a JD 4200 HST that will not move forwards or backwards and the PTO will not function. I was brush hogging (just grass, not clearing woods or anything) and my forward function quit working as did my PTO. I didn't 'feel' anything give or hear anything break. I found a thread for a 4310 discussion where the range selector shaft broke; but mine seems to be intact. It will go through the different gears just fine and you can feel them changing. The PTO light comes on but the shaft does not spin. I checked the fluid levels and all seem to be just fine. Is there an electrical component that would affect forward/backward and PTO functions? I'm not getting the hydrostatic 'whine' when pressing the pedals like maybe a switch isn't getting hit or something. Thanks.
