Mistie detection and indication.

摘要

A microprocessor-based control circuit (26) monitors mistie switches (32) provided for the knotter mechanism of a rectangular baler. Each knotter has a switch which is actuated a first time when the knotter cycles and a second time if the knotter ties a knot in a loop of twine around a bale. The control circuit controls a visual display (28) to give an operator a first indication if the knotter does not cycle and a second indication if it fails to tie the knot.
