Fits snugly on my Husqvarna 48 inch mower. NOTE: The grease nipple is mounted on the same side as the valve stem! Wonderful! Updated 03/17/20. Third wear in a season. Not a good buy. I now have 3 acres. At least twice a month. Sometimes weekly. There is no tread on one tire and almost no tread on the other. I will buy another brand next time.
