I own a Kubota B2650 Snowblower. The skid shoes are located in the rear and have been troublesome over the years (always slipping down). I would like to mount some skid shoes on the left/right side as is how Kubota is doing now. I've identified part numbers 70060-70289 (Left Skid Shoe) and 70060-70300 (Right Skid Shoe) as a possible solution. I need the skid shoe to be at least 15 3/4" in length to fit on the sides of my 50" unit. I've talked with 2 parts depts and googled for the specs of these shoes but cannot determine the length. Anyone know if these shoes will fit my needs?
