Abstract
A sweeper chain support system for allowing efficient removal of debris between a sweeper chain and a digger chain. The sweeper chain support system includes a rear roller supporting a rear portion of a sweeper chain, a pair of rear arms attached to the rear roller in a pivoting manner, a front roller supporting a front portion of the sweeper chain, a pair of front arms attached to the front roller in a pivoting manner, and a link member connected between the front arms and the rear arms. When the front arms are lifted, the rear arms are simultaneously lifted causing the front roller and the rear roller to lift upwardly thereby removing the weight of the lower run of the sweeper chain to allow for the removal of lodge debris (e.g. rock).
