Abstract
A tread assembly has front and rear main idler wheels supported by a frame. An assembly is provided to permit the front idler wheels to pivot laterally as the cart encounters uneven ground, in order to improve weight distribution across the tread and the idler wheels. The rear idler wheel also has an assembly to permit the rear idler wheel to pivot laterally. An alignment feature is incorporated into the front idler wheel assembly to permit adjustment of the alignment of the front idler wheel relative to the rear idler wheel. A tensioning mechanism is provided at the rear idler wheel to maintain the tread in tension. A bogie wheel structure is pivotally connected to the frame and positioned between the front and rear idler wheels.
