I show my way of making rolling snowblower shoes (skids) for a snowblower. I use sealed bearings as wheels for the front of the machine. The bearings I use are 1 3/4 in diameter, 1/2 in center hole and are 3/4 in over all width. 7508 DL made by General. Sold by Amazon. $14.54 each shipped with prime. Some people may have trouble with the Ariens auto turn feature, so this may be a way to help that condition out by reducing drag on the machine. The last minute of the video I show the machine in use clearing 6 inches of heavy snow. It runs perfectly! Enjoy and check out my other short videos.
