<p>An agricultural baler comprises : - a bale case (1) having an inlet opening (55) in one side wall thereof; - a plunger (5) mounted for reciprocation within the bale case (1) and back-and-forth across the inlet opening (55); - a feeder duct (52) communicating at one end with the inlet opening (55) in the bale case (1) and curving forwardly therefrom; the feeder duct (52) comprising a pair of curved opposed wall means (53, 54), one (53) of which is movable relative to the other; and - feeder means (38, 39) cooperable with the feeder duct (52) to accumulate a charge of crop material therein and then stuff that charge into the bale case (1), The movable wall means (53) is movable relative to the other wall means (54) along substantially its entire length such that one cross sectional dimension of the feeder duct (52) is variable along substantially the entire length of said feeder duct (52) to ensure that, in use and as a charge of crop material is being accumulated in the feeder duct (52), said opposed wall means (53, 54) generally maintain contact with said crop material.</p> |
