What is a grouser on a track shoe?

Expert_Answer

A grouser is the raised bar that runs across the face of a steel track shoe — the part that actually bites into the ground. Grousers give a tracked machine its traction, working like the tread on a tyre. Shoes are described by how many bars they carry: single grouser shoes have one tall bar for maximum grip and are standard on dozers; double and triple grouser shoes spread grip across two or three lower bars, giving smoother turning and less ground damage, which is why triple grouser is the normal choice for excavators. As grousers wear down, traction fades and the machine starts slipping on slopes and wet ground — grouser height is one of the standard undercarriage wear measurements. VANROCK supplies track shoes in single, double and triple grouser designs for 54+ machinery brands, with pricing quoted on request through its dealer network.
