Knew there was something wrong when we bought the tractor but it drove out fine and previous owner said he had the tractor for over two years and it was that way when he bought it...course he also said the pedal was that way because the tractor has the Reverser...didn't believe that but didn't argue with him. We are waiting on the tech manuals but would like to proceed with some maintenance issues if we can. The illustration in JDParts shows the handle which is clearly broken off on our tractor. We tried to gently lift the pedal but it doesn't move easily, so we have left it alone pending repair decision. We will not be using the tractor for any serious ground engaging work so the loss of the differential lock should never be a problem... at least it wasn't with my old Massey 65. My concern is that there could be something broken internally that could cause a real disaster if we don't address it right away. I have attached photos to show the problem. Any insight into this will be greatly appreciated.
