Abstract
A roadable track assembly (12) includes a plurality of track shoes (14) having a roadable grouser (20) bar attached to each shoe (14). The grouser bar (20) is of a size, shape, and material to provide good penetration and traction in most soils and also provides acceptable wear life. A vehicle (10) equipped with an endless track assembly (12) having the subject grouser bars (20) can travel on asphalt type roadways without causing permanent damage to the roads. Track-type vehicles having conventional metal track shoe grousers often cause permanent damage when traveling upon asphalt roads. The subject roadable track shoe grousers (20) have sufficient surface area and resilience to produce low ground pressure on the roads and eliminate damage while providing sufficient traction for agricultural work.
