Abstract:
An agricultural baler having an hydraulic actuator and accumulator being interconnected such that the upward force of the hydraulic actuator on a bale chute in a first position of the bale chute is smaller than the downward force generated by the combined weight of the bale chute and a completed bale on the bale chute but in a second position of the bale chute is larger than the downward force generated by the weight of the bale chute to cause a completed bale to slide under the action of gravity along the bale chute and to fall onto the field from a trailing end of the bale chute.
Abstract:
A method for controlling a braking mechanism for a supply roll with wrapping material for a round baler that passes through a first phase wherein, after detection of sufficient crop material in the baling chamber, wrapping material is brought up to the baling chamber and introduced into the baling chamber. The braking mechanism provides a higher braking force during the wrapping operation than the first phase. The wrapping operation is started on detection of movement in the wrapping material. This prevents the braking mechanism from being activated prematurely and leaves sufficient time to deactivate the braking mechanism after the wrapping operation.

Abstract:
An agricultural harvesting machine, such as a baler, is provided with a pick-up assembly and a feeder mechanism for picking up crop material from a field and feeding it to the inlet of a baling chamber. A crop retainer mechanism, such as a windguard, are mounted above the feeder mechanism for engaging the upper portion of said crop material whilst it is being fed to said inlet. The retainer mechanism is movable between a lower position assumed when no crop material is present on said crop intake apparatus and an upper position when a considerable amount of crop material is present on said crop intake apparatus. The harvesting machine is also provided with a dampening mechanism for damping the motion of said crop retainer mechanism. Advantageously, the motion is damped by a pair of gas springs mounted to the transverse rod of the windguard. This arrangement precludes sudden movements of the windguard and ensures a regular flow of the picked up material to the baling chamber.
