Abstract
In a rectangular baler provided with a reciprocating plunger that compacts each new charge of crop materials against previously compacted material and incrementally advances the compacted charge toward a restricted discharge opening at the rear of the baler, the compressive load in the connecting rods of the plunger is sensed during each compaction stroke and is compared with a preselected value to determine whether the size of the discharge opening should be increased or decreased in order to maintain the selected load value. A sensor in each of the connecting rods is in the nature of a transducer that causes a change in the frequency of an output signal in accordance with the compressive loading in the connecting rod, such output signal being delivered to a controller which in turn regulates the operation of hydraulic mechanism to increase or decrease the size of the discharge opening.
