Abstract: A control system for an unload drive system of a combine and a method for controlling an unload drive system of a combine by sensing a force on an unload auger. The combine includes a grain tank for storing grain and at least one auger for unloading grain from the grain tank. The combine includes at least one movable auger cover coupled to the grain tank for controlling the amount of grain to flow into the at least one auger. The control system includes at least one sensor for sensing a force on the unload drive system and a controller for receiving at least one force condition from the at least one sensor representing the sensed force on the unload drive system and causing the at least one movable auger cover to move based on the sensed force condition.

Abstract: A sheet material lifting and retaining apparatus including a shaft member having a longitudinal axis is described. A gas cylinder assembly is secured to the shaft member, the gas cylinder assembly having an axis of operation that is generally coaxial with the longitudinal axis of the shaft member. A sheet material contact member is secured to the gas cylinder assembly. The shaft member can include a length adjustment mechanism, which may be provided as a telescoping tube arrangement having a plurality of telescoping aluminum tubes. The gas cylinder assembly can include a self-contained gas cylinder. An end fitting can be secured to a first end of the gas cylinder, with a shaft attachment member secured to a second, opposite end of the gas cylinder. An actuator can be provided to selectively control actuation of the gas cylinder. The actuator of the gas cylinder assembly can include a rod portion extending generally parallel to the shaft member.
