ABSTRACT:
An automatic twine-wrapping mechanism for a large round baler. The mechanism comprises (1) a twine dispensing mechanism for dispensing twine into the bale-forming chamber of the baler, (2) a reversible hydrualic drive means for cycling a twine arm of the dispensing mechanism back and forth in front of the chamber, (3) a twine wrapping control mechanism (a) for initiating a twine wrapping cycle by sensing the growth of a bale to a predetemined diameter by automatically actuating a pump drive means for driving a hydraulic pump and by positioning a hydraulic control valve to condition the hydraulic drive means to cycle the twind arm and (b) for terminating a twine wrapping cycle by deactivating the hydraulic drive means following the wrapping of twine around the bale. The twine is automatically severed by a twine cutter responsive to the movement of the twine arm following completion of the wrapping of the twine around the bale. The baler operator actuates a bale ejection mechanism following the cutting of the twine. Following bale ejection, the twine wrapping cycle is terminated by the twine wrapping control mechanism sensing that the bale chamber is empty. The baler is now ready to begin the formation of another bale therein. The wrapping control mechanism may be preset to the diameter at which it is desired to initiate the wrapping mechanism. The wrapping control mechanism also includes a manual override control linkage for initiating a twine wrapping cycle a bale diameter different from the preset diameter and for recycling the wrapping mechanism, if necessary, prior to ejection of the bale.
