ABSTRACT:
An apparatus for coordinating the operation of the bale tying mechanism with the feeding apparatus of a baler. The baler (10) includes a bale chamber (16), feeding means (26) including a pair of feed rollers (36) which are moved back and forth across the inlet end by reciprocating means (46, 48) including a hydraulic cylinder. The bale tying means includes a knotter (64), a pickup needle (110), and a knotter shaft (76) capable of driving the knotter and the needle. The actuating means which is capable of actuating the bale tying means includes a bale length metering mechanism (202 to 218), a constantly driven sprocket (230), and a single revolution clutch (220), the actuating means being capable of initiating the operation of the clutch (220) to cause rotation of the knotter shaft (76) when the bale length has been achieved. The coordinating apparatus of this invention which is capable of preventing the operation of clutch (220), except when the pair of rollers (36) have been reciprocated to their desired position, includes a bell crank (238) and a slidable link (236), both normally spring biased to a stop position but capable when one end of the bell crank is engaged by the reciprocating means to enable operation of the single revolution clutch (220).
