I have a 05 Polaris 6x6 with big tires in front and tracks. When I try to clime out a deep mud hole or go up a steep hill (> 100%) in low and 6-wheel drive my machine tried to roll over backward. The problem appears to be the front end is so light that the tires it will not stay down. Last week I made a rack so I could put a 5 gal gas can in front of the of the front rack to help weight down the front end. This help but not as much as I would have like. Do other people have the same problem?
