Cutting down the lugs of a snowmobile track-Take 2

This is the latest video of cutting down track lugs. Since the first time we did this we learned that if you use a piece of flat stock instead of a pipe the lugs are even more straight and even. We made this Challenger 153 into a 1.625 height and then used a notcher to cut new teeth in the track. The notcher was made from a slip joint pliers and has a utility knife blade heated and bent into a U-shape and then welded to the end. No heat was needed to nip or saw the lugs. One side of the back edge of the sawzall blade for cutting the lugs down was ground on a bench grinder to a knife edge.

I get cutting lus down..Why the silver dollar sized holes in track.?

@maxwwell20  Was like that when we got the track for cheap. Porting for lighter weight, less rolling resistance ect.

@quader99 not much, 1/8 will do nothing. This is done to give better traction for stopping and going on trails (which is all we have around here) less track overheating which will cause lugs to break off, and better slide life. If we lived in the mountains 24/7 we would have no need to do this.

@SNOMAN1174 Afer reading that comment, it makes alot of sense now. I just got a 2010 rmk not to long ago and the lugs rounded already a bit but if i was to cut down 1/8 how much would it stiffen it up

@iwant2partywitu You cut the lugs down to stiffen them. This is very common on tracks like the 5.1 series polaris track. From the factory the are so soft and will "fold over". people cut them down about 1/8th inch and sometimes even put in traction screws. The stiffer lug will perform much better in set up snow

why would you want to cut down the lugs:?
