tn85a lost fwd

[sammyd]

was out moving snow and all of a sudden the tractor couldn't pull itself off the road. Looks like the front wheels are not trying to move. Switch is on and the light is on in the dash. Operators manual is less than worthless. I found a picture of a fuse and relay panel but it doesn't tell you where it is and nothing about the fwd in the troubleshooting section. I have part of the lower dash removed from another issue and I don't see it there. This has the 16x16 with electric shuttle. Any hints or clues....Where are my fuses and relays? Is there a solenoid somewhere that needs some attention?
thanks

Start to check the mechanical bit, it's common to use oil pressure to disengage 4WD on tractors so a dead solenoid should get you permanent 4WD. But of course not all uses this way of doing it but a basic mechanical check is quick to do.

Evidently there is a coupling held in place with some snap rings and the snap rings let go. Dealer said it is not too uncommon.
