I have a 450H dozer and the dozer tracks more to one side then the other, and sometimes it locks up and if you turn the dozer off and then start it it run ok but still tracks to one side sometimes. what could that be? Wondering if anyone else is having these issues?
Track sensor, usually opposite side of the side thats giving you trouble. switch them and see if the problem switches sides. thats a low cost check, track sensor around 3 hundred and most times need to be calibrated.
