Over-the-tire rubber tracks add traction and flotation to John Deere 200 and 300 Series skid-steer loaders. The tracks can be mounted over 10- and 12-inch pneumatic tires, including standard, extra-wall and hauler models. No special tires are required. Track length is adjusted by selecting rubber joints of varying length. A skid-steer with over-the-tire rubber tracks can travel up to 12 miles per hour with two-speed option.
