Abstract
An agricultural forage box includes an infinitely positionable variable speed drive system and an improved trip mechanism. The variable position drive system utilizes a drive belt for driving the floor conveyor of the forage box, which is driven in response to rotation of a pair of sheave sections. One of the sheave sections can be moved relative to the other, and a sheave positioning mechanism provides adjustment in the position of the movable sheave section. The variable position mechanism includes a yoke which is movable in response to operation of an actuator plate and linkage mechanism, which in turn is interconnected with a control lever. The improved trip mechanism includes a trip bar mounted to the forage box for pivotal movement about its longitudinal axis. A trip lever is located adjacent a declutching tab associated with the power train. A pair of cables extend between the trip bar and the trip lever, and are connected one on either side of the trip bar longitudinal axis. With this construction, pivoting the trip bar in either pivoting direction tensions one or the other of the cables to move the trip lever into its operative position to stop operation of the unloading components of the forage box.
