Abstract: A work machine having a belt tensioning system is described. A belt is engaged with an engine drive sheave and a driven sheave of a rotor having a plurality of cutting tools configured for reducing wood infeed material. An idler pulley is mounted to an idler arm that is hinged to the machine frame. An actuator is hinged to the idler arm and the frame. The actuator may be extended and retracted in order to press the idler pulley into stronger and weaker engagement with the belt in order to set the desired amount of tension in the belt. One or more sensors may be used to sense the amount of tension in the belt, and the one or more sensors may be in communication with a control system that controls the actuator to monitor and adjust the belt tension so that it is maintained within desired limits.

Abstract: A rail mounting system may have a rail and a slide member. The rail has a base, two sidewalls, lip portions and ribs. Channels are formed by portions of the rail. The slide member has tabs with grooves that define legs. The lip portions and the ribs are slidably located within the groves and the legs are slidably located within the channels for selective movement of the slide member with respect to the rail.
