Hi all, I'm thinking of a new project that being a set of half tracks on one of the Power King tractors, would use a set of old snowmobile tracks my friend has a couple of 121's he'd let me try, for the boggy wheels I'm thinking a set of front turf wheels and tires from a lawn tractor, the tracks would go forward from the rear tires vs going to the rear, the thing I'm trying work out is how to attach the boggy wheel assembly should I go with a ridged forward axle and a center arm under the tractor with a system to put tension on the tracks and them springs on the axle to keep the boggy wheels down or would individual support arms be better? What do you all think?? Here's a Bombardier manual showing their system
