The drawing-in and mowing drums are disposed in the transverse direction on either side of the vertical longitudinal center plane of the machine centrally ahead of a chopper which has an insertion duct which takes up the cut, harvested crops. The insertion duct is bounded above and below by two insertion rollers disposed at a height from one another and laterally by two conveying drums which are at a transverse distance from one another. The conveying drums transport the cut, harvested crops along and rotate about vertical axes.

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.

Abstract: A method and apparatus for controlling movement of a work implement movably connected to a work machine. Movement of the work implement is controlled by manual and automatic control valves that are associated with “manual” and “automatic” modes of operation. The manual and automatic control valves are connected between hydraulic motors for controlling movement of the work implement and a hydraulic fluid supply. Each of the manual and automatic control valves governs hydraulic fluid flow to the hydraulic motors. A pressure sensing device is associated with the manual control valves to detect operator modulation of the manual control valves and thereby alter operation of the automatic control valves in the “automatic” mode on the same side of the implement.

Abstract: A harvesting of fruit from trees utilizing a harvesting machine which continuously advances along the row is explained. The harvesting machine utilizes a canopy penetration, fruit engagement and pressure severing method of mechanical harvesting. A plurality of arm members are held by an arm housing in either a single vertically disposed row or in a plurality of vertically disposed rows. During a harvesting procedure the arm housing undergoes a series of motions including rearward and forward on the harvesting machine as well as outward and inward therefrom. These motions may be controlled in an endless number of combinations to produce a desired harvesting action. One such harvesting action involves isolating to eliminate influence of the forward motion of the harvesting machine from the arm members during an extension motion and a retraction motion into and out of the canopy of the tree so that the arm members may enter the canopy with minimal resistance.
