I have an '07 Prairie 360. I've burned the belt on it when it was 2 months old simply towing two 10 year olds on a snow sled in the snow = glazed spot on belt = new belt at $100. ( I didn't think that 'low' was necessary in this situation but apparently it was. I always use 'low' now for any towing, but of a hassle thought because if you have to go any distance you have to do it slow. I've never burned the belt since and I've towed so heavy 4x8 trailers heaped with cord wood over rough terrain but the belt is fine....My question is this.... I was wondering about towing a small 5 wheel tractor disc to turn up some of the back field to plant feed for the local deer. In 'low' I think I can do this because I was recently at an ATV pull and most of the machines were CVT set on low. They pulled the sliding weighted sled until the weight moved so far forward that the ATV would come to a stop even though all 4 wheels were still spinning and apparently not damaging the CVT belt. This example gave me renewed hope for the ability of the CVT and now I'm considering towing this disker to plough a bit. Do you think that the belt will survive? Have any of you towed extremely with a CVT?

My worry is not just the burnt belt, but the more expensive aluminum converter sheaves that gets damaged as well in extreme case.
