Traction Deere 4710 MFWD not engaging

mfreund · Nov 29, 2014

If you had a bad soleniod, the MFWD would be engaged. When the circuit looses power to it the MFWD soleniod defaults to engaged MFWD.

If you have a tech manual, you have the test.procedure. follow it with a volt meter.

Have you got this problem solved?

I thought I'd go ahead and provide an update to this issue just in case someone has the same problem down the road. I just got it fixed today. The problem was, in fact, a stuck solenoid. I checked all the electrical connections following the procedure in the manual and everything checked out there. So I decided to bite the bullet and call my closest dealer.

Sure enough, while he said that my case is unusual, a solenoid can be stuck in either direction, power flowing to it or not. Therefore, it's not necessarily true that a bad solenoid will default the tractor to 4WD. In most cases, that would be true, not here. Mine was stuck almost fully extended whether the switch was on or off, which did not let the hydraulics engage the pin to lock into 4WD. Had it been stuck in the other direction, I would not have been able to disengage it which is the most common issue I found when searching for my problem.

So, problem solved. Hope the price of my service call helps out someone one day.

Now bring on the snow... or not.

I have a 4710 and had the same issue. Called the dealer for a service call and my problem was the small piston underneath the tractor was not moving when the MFWD switch was pressed. I guess that mud and crap encased it as I wasn't using MFWD very often. I now make sure to lubricate this piston at least twice a year. No problems since.
