raid tracs and rattracks are different machines the raidtrack is about the size of a cushnan trickster mine has a 18 horse techumsa f head motor in it whitch is also an obsolete engine they are driven by a snowmachine clutch and belt system and use an open clutch and brake system to steer so like most older dozers they aren't going to steer well in deep soft snow especially when pulling weight a kolher engine from the old john deer 6x4 gators make a good conversion but have fun finding one there is a reason why mine is still sitting in the backyard.
