Still have the 2 speed hydrostatic rear end I wouldn't mind selling (funny that this one DOES NOT have a oil filter on it).? Also, I recently saw a youtube video about this style Jacobsen tractor stating the rear end has a limited slip differential - not sure if I believe that cuz I am pretty sure if I throw a tire chain when I'm snowblowing that I stop like RIGHT NOW and spin a tire. Anybody know for sure?? I guess I could try not being lazy about it and dig out my owners manual and see if it says anything about it.
