A guy on another forum sent me a PM, that included the following advice:
"One final point. brand such as Polaris and can-am don't work well with tracks because they don't have locking front differentials or in Polaris's case if the rear wheels stop spinning in 4wd the power to the front wheels/tracks is cut off and you go back to 2wd. Which for tracks is a big problem. I found out the hard way and on top of all this it's written in the manual (small print)."
