Summit Supply LLC carries a full line of sprockets for Bobcat Skid Steers. In stock are sprockets for Bobcat T250, Bobcat T300, and Bobcat T320 as well as the other models of Bobcat Skid Steers with rubber tracks. There are two different styles of sprockets for Bobcat skidsteers, a deep dish and a shallow dish. The easiest way to find the difference is to get the casting number off the outside of the sprocket. This will be a seven-digit number starting with a "6" or a "7".
If you cannot get the casting number, you can measure the height of the dish.
