We have 2 9500 combines a early one and a late one. The early one has the 2 position throttle idle and wide open. I was wondering if there was a way to make the early one a 3 position throttle? Thanks for any help
I do not believe it can be done easily. Along with the toggle switch, there is a difference in the injection pump that cannot be upgraded (without changing the whole pump). The 2 position throttle was very unpopular here and when they introduced the 3 position throttle in 1992 the first thing JD told us at their service school was "NO, older models cannot be upgraded". A quick call to your JD service department will confirm.
