<p>An agricultural baler operable to produce square bales and comprising a bale case (12) having an inlet opening (70) formed therein, a feeder (54) communicating at one end (68) with the inlet opening (70) in the bale case (12) and feeder means (80) operable to feed crop material into the feeder duct (54) to form a wad of crop material for subsequent transfer to the bale case (12), a wall (58) of the feeder duct (54) being provided with movable means (90-96) operable to assist in the movement of crop material within the feeder duct and contactable by the crop material as it passes through the feeder duct, whereby the frictional forces produced by the passage of the crop material over that wall of the feeder duct are reduced. Alternatively, a fixed further wall member 181 may be provided inwardly of a bottom wall 180; said further wall member 181 being provided with elongated slots through which the feeder tines 82, 84 penetrate whereby wedging of crop material inbetween the feeder tines and the bottom wall 180 virtually is eliminated.</p> |
