Abstract
A pair of guide rollers contact the side surfaces of the guide blocks of an endless elastomeric track belt and guide the guide blocks into a space formed between a pair of spaced apart idler wheels. The guide rollers prevent undesirable frictional contact between the guide blocks and the idler wheels, thereby increasing the useful life of the idler wheels and the guide blocks.
