how thick is the material you're using for your squeegee? it should be 3/4". It should hang down approximately 3/4" below the were bar. with the squeegee your skid shoes should be lifted up to the highest position and not even touch the ground. I suspect that the $7 strip that you got from tractor supply is way too flimsy to be used as a squeegee. others have posted on the forum their experience with thinner pieces of rubber or conveyor belt, the consensus seems to be that the horse stall mats are the best way to go. Do a search of the forum for squeegees and you will find pictures of what others have done. The horse stall mat available at tractor supply works very well. one horse stall mat will last you a lifetime.
