Tractor
5225 & 3720
this tractor is open station and i assume it is ehydro but i sure can`t tell by reading the manual. this tractor has one toggle switch on the right fender which is the cruise control. It works part time. so what is wrong? yesterday would not work at all.

I'd start with the service tech manual for the 3720, if me.
Or hope that someone has one that can chime in on trouble shooting this problem. Suspect it is ehydro. My toggle switch on the 4300 just clamps (magnetic) onto the forward pedal at whatever it is at. Simple and easy to trouble shoot.
Might be more involved with the 3720.

I had a 2004 4720 cruise become unstable, sometimes it would work but would not maintain a steady speed & it was a mfwd sensor. If you are in the seat it was on the left side of transmission, JD had to order it and I think it was $65 about 5 years ago, it is the one held in by a bolt you can see a partial number on pigtail also I would get an error code of 06 sometimes.
