Claim Text:
1. An agriculture baler of a rectangular type comprising: a wheeled frame; a baling chamber mounted to said frame and extending generally fore-and-aft with respect to an intended direction of movement of the baler and having an inlet opening in a lower wall thereof; a compressor mounted for reciprocation within the baling chamber over the inlet opening for compressing successive charges of crop material fed through said inlet opening into said baling chamber to form a bale thereof; a feeder duct communicating at one end with the inlet opening in the baling chamber and curving downwardly and forwardly there from and terminating in a lower, forwardly facing open crop receiving mouth; this feeder duct comprising upper and lower curved walls of which the upper wall comprises slots, extending generally from said crop receiving mouth to said inlet opening in the baling chamber for cooperation with feeder tines; a feeder comprising a feeder fork with feeder tines, wherein the feeder is configured to move the feeder tines along two distinct trajectories, a packing trajectory for accumulating a charge of said crop material in the feeder duct, and a stuffing trajectory for stuffing said charge of said crop material into the baling chamber, wherein: the movement of the feeder is directly derived from and synchronized with the movement of the reciprocating compressor through a linkage spanning between the feeder fork and a pivot point where a pitman arm attached to the compressor, and the feeder fork comprising at a first rearmost end for cooperating with the feeder duct a series of laterally spaced-apart elongated feeder tines, and at a second rearmost end is rotably attached to the linkage, the linkage comprising a pair of cranks connected through pivots, and wherein the fulcrum of the feeder fork is rotably coupled to a first end of a spacer rod and the spacer rod is rotably coupled at a pivot point at a second rearmost end to the wheeled frame.
