Patent abstract
A turf device driven by a traction drum. The traction unit is connected to the tool by an articulable joint which allows the traction unit to rotate horizontally (yaw) and vertically (pitch), as well as roll side-to-side in relation to the tool. The articulation allows the tool and the traction unit to follow undulations in the terrain separately and allows the mobile object to turn by yawing the traction member in relation to the tool.
