I fixed up a Cub Cadet 882 to plow with. Ive been doing the plow day thing for about 3 years now, and Ive never had to remove the rear wheels. Well I sold the 882, and was able to keep my tires. When I pulled the right side rear wheel off, I found a little more dirt than I expected. I usually would wash it after I got home from an event, so this was slightly un-expected. I guess Im not washing as good as I thought. Anyways, I just wanted yall to be aware of the dirt that can get packed in, on the furrow side, of the rim, on the axle and in my case, around the brakes. That makes sense as to why it wouldnt stay parked on a hill.
