Just picked up a used 09 800 h.o. with rebuild,tracks,heated cab etc… However 314 miles in we were in were playing in the sand dunes off Lake superior and heard a noise from the rear end. Wifey was driving… Now the machine won’t go forward or reverse in awd or in rwd. The rear tires "ratchet" fronts don’t engage. Had to get towed out by our 16yo sons big bear ( embarrassing). I’m hoping it’s the diff and not the transmission. Maybe coupling? Fork?
I’ve dug thru the threads forhours trying to find an exact relation and came up more confused.
BTW we sold off out Tractor supply Massimo msu 500. Was a great trouble free machine but too darned slow…
