the vehicle. Grousers are typically made of metal, such as forged steel, and are not designed for use on paved roads. Various devices, with names such as road bands, have been developed to temporarily cover grousers/cleats in order to allow a vehicle to travel on paved roads.
Grousers have been used in such exotic environments as the deep sea floor, and the surfaces of the Moon and Mars. Snowmobiles once used cleated tracks, but racing snowmobiles are banned from using cleated track for safety reasons and instead

Grousers are devices intended to increase the traction of continuous tracks, especially in loose material such as soil or snow. This is done by increasing contact with the ground with protrusions, similar to conventional tire treads, and analogous to athletes' cleated shoes. On tanks and armoured vehicles, grousers are usually pads attached to the tracks; but on construction vehicles they may take the form of flat plates or bars.
Similar traction-improving patterns have been implemented on the surface of the wheels on tractors. These include
