My T2334 will not go into 4x4 is this an electrical or a mechanical problem? this happened all of a sudden. the 4x4 worked when I pareked it on my trailer but when I tried to get it off the trailer to plow with itfor the blizzard here in Massachusetts it would not go into 4x4. I could not get it to come off te trailer without getting stuck! Could someone please lead me in the right direction. Thank you.
