Hoping other owners can help.
My EHSS jerks into gear like you are popping the clutch when using the inching pedal/clutch pedal. If you start from neutral and move the FWD/REV lever into FWD and do not use the clutch the machine makes a smooth take-off. Same for REV.
It may be the pedal position potentiometer of the EHSS module. I measured the pin voltage on the EHSS in order to test the pot and there was no voltage. Is there another way to test the pot itself. Is this just a wire wound pot that I can measure resistance on?

Waiting on suggestions/answers.

There are some related threads listed down along the bottom of this page. I remember some of the discussions, and it is usually a frayed or poorly adjusted inching pedal cable, or a bad potentiometer. Also could be moisture and/or corroded connections on the potentiometer.

Turns out the potentiometer is just a 3 wire, pot that can be measured with a Ohm meter.

Did you get it figured out Shaley? I have this same tractor, I had to replace the cable and potentiometer several Yrs ago but it's been good since (I hope 🙀)
