This is a track drive wheel for MTD, Yardman, and other track series snow blowers. This is the rear drive wheel assembly on the track snow blowers and the hub size is 3/4. It was originally made out of plastic with a metal center hub, but MTD has decided not to make this part no longer. I got tired of junking good track series snow blowers just because I needed drive wheels for the track. So I have designed and welded this all metal part. It is made to exact specifications as the original part except it is all metal and will last longer than the cheap plastic ones. So this part will work on the rear track drive system of MTD and Yardman snow blowers. This part is laser cut and welded by a professional welding team so it will probably last longer than your snow blower will. Again I designed this because I could not find anything on the internet and no obsolete parts to fix a snow blower that I was working on for a good customer and it is crazy that MTD no longer makes th part. I have added a picture of the 1 that i installed on a snowblower so you can see what it will look like. 7 1/2 outside diameter.
