Abstract: A wrap material dispensing system for a round baler includes a wrap material drive system for advancing wrap material from a supply roll to a wrap material feeding arrangement, and a selectively operable knife mechanism for severing the wrap material. The wrap material drive arrangement includes a pair of rollers that are driven by a motor. The knife mechanism is mounted to a pivotable shaft to which a one-way knife actuating clutch is mounted. A flexible drive member, such as a chain, is engaged with a rotatable output member of the drive motor, and with the one-way knife actuating clutch and a driven one of the wrap material drive rollers. Operation of the motor to rotate the motor output member in a first direction causes advancement of the wrap material, and the one-way knife actuating clutch is configured to maintain the knife mechanism in an inoperable rest position during advancement of the wrap material.

Abstract: An operation sensor for a wrap material dispensing system of a round baler. The operation sensor includes a rotatable member with which the wrap material is engaged, and which rotates along with the wrap material as the wrap material is fed to a wrap material feeding arrangement for introduction into the round baler. Rotation of the rotatable member is detected by a sensing arrangement, which is interconnected with a visual display for providing a user with a visual indication as to the rate of advancement of the wrap material.

Abstract: An overload and overfill protection system for a round baler includes a selectively engageable drive mechanism located between a rotary input member of the baler and an input driven member, such as a sprocket, which drives a pickup mechanism forming a part of the round baler. The selectively engageable drive mechanism includes a fixed drive member mounted to the rotary input member, and a shiftable engagement member mounted to the sprocket for movement between an engaged position for transferring power to the pickup mechanism, and a disengaged position in which power from the rotary input member is not transferred to the sprocket. The fixed drive member is in the form of a shear bolt, which is sheared by an overload force applied to the engagement member when the pickup mechanism is overloaded so as to disable the pickup mechanism. The overfill protection system is in the form of a clutching mechanism interconnected between a movable member of the baler, e.g.

Abstract: A crop material feeding and directing system for use with an agricultural implement having a crop pickup which is wider than a crop inlet associated with the agricultural implement. A lower roller member includes a central portion which extends across the crop inlet, and auger sections at its ends located outwardly of the crop inlet. A pair of upper stub augers are located above the end auger sections of the lower roller member. The stub augers and the end auger sections of the lower roller member cooperate to inwardly direct crop material which is supplied by the pickup mechanism to a location outwardly of the crop inlet, and the central portion of the lower roller member functions to move the inwardly directed crop material rearwardly into the crop inlet.
