I just put a 144" track on my MM 700. It had a 136" track on it before so I did a suspension set back and slightly dropped the suspension as well. I made sure that all of the mounting locations were at the exact distances as stock. When the track is off the ground, the track turns just fine. When I tried to load it onto my trailer, it smoked the belt and did not want to turn the track. Nothing is rubbing and everything free wheels fine without a load. Any ideas?
