Abstract
A rectangular baler has a density control for controlling the density to which crop material is compacted by a cyclically operating plunger, and a cyclically operating tying mechanism for tying loops of binding material around successive lengths of the compacted crop material to form bales. In order for the tying mechanism to function properly the binding material must slide between a tied bale and the crop material being compacted against the tied bale. If the sliding friction is too great, the binding material breaks or is pulled free of the tying mechanism thus resulting in failure of the tying process. To reduce the sliding friction, the compaction density is reduced for an interval of time following each cycle of the tying mechanism. The interval of time may be tolled by counting a number of plunger cycles immediately following a cycle of the tying mechanism, the density control being set for reduced compaction density until the number of plunger cycles has been counted.
