OK, this is my first post. Have had my 4610 for several years. It just started lurching and stopping, and lurching again in all drive gears, in 2 or 4wd, forward and reverse. Starts after it gets a little warm (i.e. 15-20 minutes). Dealer has had it for 2 weeks now and can't seem to diagnose the problem. Tried changing both filters and replaced 8 gallons of fluid; no help. Only has 600 hours on it. Anyone have similar problems with JD ehydro lurching when it warms up??

Welcome to GTT,
Two common problems is the wiring under the pedals, it's easily damaged but that does not sound like your issue. Next is the engine speed/MFWD speed sensor, when they fail lots of weird things can happen.
