I've been having an issue since day 1 with my h12. The machine drives fine when you first start it up, but once the hydro oil gets around 110f the tracks stop working independently. It has no problem driving straight, but i can't turn. The engine just revs and strains and i won't get any movement unless both tracks are moving the same speed and direction. After turning the machine off and letting it cool it works fine again. I just purchased the oil cooler kit and I'm hoping it helps. Any idea where this problem is coming from?
