Update on tires don't spin. I have done some more testing and changed hydro filter. It will spin in low gear if you jerk it around and drive like an idiot. Overall I think it is performing as it is supposed to. Traction is just not a problem. I kind of miss the old gear drive...This video link...
I've had it about 2 months it's about 4 year's old. It doesn't load up or stall it just stops moving forward..it will stall out if you hold the brakes.. 330 hours.
Rear tires are liquid filled. No weights. Loose dirt . 2wd. Or 4wd. No squealing from hst relief valve. It will not spin at all. Rpm from idle to wide open. It's the same no matter what I do.
