  • Patent number: 4738092
    Abstract: An apparatus selectively operable either to invert and laterally displace the windrow from its original position or merely to laterally displace the windrow without effecting an inversion thereof is disclosed wherein a first discharge chute can be utilized to effect an inversion of the windrow while a second discharge chute can be utilized for merely shifting the windrow without inversion. The discharge chute is positioned laterally of and adjacent the discharge end of a cross conveyor conveying an elevated windrow of crop material laterally of its original path of repose upon the ground. The first discharge chute redirects the flow of crop material forwardly and over a discharge edge whereupon the forward motion of the apparatus will effect an inversion of the windrow into a second path of repose laterally spaced from its original path.

  • Patent number: 4736577
    Abstract: Apparatus for moving hay and turning it over from a first swath to a second swath, comprising a movable platform disposed in a substantially horizontal plane and having a generally semicircular shape, the platform having an upstanding curved wall on the outer edge of the curved side and rear portions thereof. A device is mounted on one side of the front portion of the platform for picking up hay in the first swath and depositing it on the adjacent portion of the platform as it is moved forwardly. A plurality of radially outwardly extending arms with depending tines are mounted on the platform for rotation in a substantially horizontal plane above the platform. The tines engage the hay deposited on the platform and move it along the platform in an arcuate path of approximately 180.degree. to the opposite side of the platform and over the front edge thereof to deposit the hay in an inverted position in a second swath laterally spaced from the first swath.

  • Patent number: 4366666
    Abstract: A haymaking machine has a substantially horizontal main frame beam with lateral carriers which are pivotable upwardly and downwardly relative to the main beam. The pivots define horizontal axes and pivoting takes place between a working position in which the beam and carriers are substantially horizontally aligned, and an inoperative transport position in which the carriers are turned upwardly relative to the frame beam through 90.degree. or more. Breakage of, or other serious damage to the drive transmission to rotary rake members of the machine is prevented by drivingly connecting a rotary shaft within the main frame beam to the rotary shaft segments housed within the carrier by double universal couplings which still allow the shaft segments to be driven when they are inclined to the main beam at 90.degree. or more. Also, the carriers mount crop guides that can be pivoted about horizontal axes and/or displaced relative to the rake members so as to function during either tedding or swath forming.

    Abstract: A haymaking machine has at least one rake member, preferably two members, with tine groups that are rotatable about an upwardly directed axis. Adhesion of hay and/or other crop to the tine groups is greatly reduced, as compared with conventional constructions, by arranging fastening spoke ends between the helical coils of each tine group. A spring-loaded setting device is arranged to co-operate with a retaining bracket of each tine group to retain the tines, and corresponding tine carrier portions, in either a position suitable for swath formation or a position suitable for tedding operation. Each spoke end is substantially rigidly clamped between the corresponding turnably mounted coils of the tine groups and the spokes extend directly away from their connections between the coils towards the axis of rotation of the rake member. Guides at the rear of the machine assist to deposit the crop in swaths or the guides can be set to ted the crop.

  • Patent number: 4274248
    Abstract: A hay harvesting machine contains a rake wheel whose housing is formed by an upper housing portion non-rotatably connected with a vertical upright shaft and a lower driven housing portion rotatably mounted at such upright shaft. In bearing bushings rotatably mounted at the lower housing portion there are retained tine supports provided with raking tines or prongs. These tine supports extend in an essentially horizontal plane and, by rotating the bearing portions, can be selectively shifted from a first operating position into a second operating position. In the first operating position the tine supports extend approximately in tangential direction and in the second operation position they protrude essentially in radial direction from the upright shaft. Each tine support is connected with a control lever engaging, by means of a control head or follower, into a control track or cam. This control track is located in a plane extending essentially perpendicular to the upright shaft, i.e. horizontally.

  • Patent number: 4254609
    Abstract: An agricultural implement for carding, combing and/or teasing crop lying on the ground by receiving same from the ground by comb-like structures and then engaging and conveying the crop through the implement by a rotating drum with tines extending therefrom or rotating discs which have substantially vertical axes, the crop being restrained as it is engaged to impart somewhat of a combing action. In embodiments having a rotary drum with tines which rotates about a horizontal axis, further rotating tines in the path of the conveyed crop tend to comb and disentangle the crop further. The latter such tines may be close to or actually within the cylinder of rotation traced by tines extending from the drum although direct contact between the two sets of rotating tines is avoided.

  • Patent number: 4208863
    Abstract: An agricultural machine, such as a haymaker, for the displacement of stalks, comprising a movable air-permeable screen and air displacing means arranged to induce a pressure difference across the screen thereby to cause stalks to adhere to the screen under the effect of suction. In a preferred embodiment, a blocking member is disposed to prevent the application of suction at one region of the screen to allow stalks adhering to the screen to be deposited. The air displacing means may be arranged to provide an air cushion under the machine to support the machine above the ground.

  • Patent number: 4166352
    Abstract: A hay-making machine having a plurality of rotary rakes thereon which are rotatably driven about generally vertical axes or rotation. The hay-making machine is supported by a plurality of wheels to facilitate its movement relative to the ground. The hay-making machine is connected by a hitch mechanism to a tractor and the rotary rakes are driven by a shaft connection to the power take-off equipment on the tractor. The hay-making machine is comprised of a main frame and auxiliary frames. The main frame is pivotally secured to the hitch and the auxiliary frame is connected pivotally to the main frame to compensate for variations in ground irregularities. Telescoping shafts are utilized on the machine to facilitate a change in length between the rotary rake members and the hitch as the hay-making machine moves relative to the ground.

Each member has horizontally extending tine carriers, the outer ends of which have holders with tines and a swash plate is mounted on the respective shaft of each member. A rotatable ring on the plate is connected to each carrier via a corresponding universal pivoted lever that turns the tines to a downward crop engaging position when in their foremost positions to raised crop disengaging positions in their rearmost positions, considering the direction of machine travel. Each carrier is a hollow beam and the beams of each member cross one another adjacent the shaft that defines the axis of rotation of the rake member.

  • Patent number: 4157644
    Abstract: A haymaking machine has at least one, but preferably two, tined raking heads that are driven to rotate about upwardly extending axes from respective mountings. The mountings are connected to the rear of beams that converge forwardly to a right angled junction and a common gear box. Crop passing between the rake heads is thus unobstructed by an overhead frame. A coupling near the junction is connectable to a three point lifting hitch and a pair of spaced apart plates form a pivot connected at one side of the plates adjacent the junction. A retaining element secures the beams in operative positions about the pivot. Each rake head has one, but preferably two, ground supporting cylinders that are positionable around the rake head's axis of rotation. A rear crop guide is pivoted to each rake head near its mounting by a quadralateral linkage that can be set in any one of plurality of guide positions.
