  • Publication number: 20100293915
    Abstract: The present invention relates to an economical wheel rake having two arms that adjust from transport position to an operating position using a combination of an actuator and a dual axis articulating joint. The hay rake apparatus having a wheeled frame, a rake arm having a trailing end and a leading end, an intermediate arm having a first end connected to the frame and a second end which is fixed to the rake arm, a dual axis articulating joint connecting the frame to the intermediate arm, a telescoping actuator attached to the wheel frame using a first actuator joint and to the intermediate arm using a second actuator joint. The dual axis articulating joint is pivotable on a horizontal and a vertical axis when the telescoping actuator extends or retracts causing a longitudinal and a latitudinal angle between the intermediate arm and the frame to change. The rake arm and rake wheels are therefore moveable from an inoperable transport position to an operable position.

    Abstract: A hay harvesting machine including a frame with several windrowing rotors, the frame including a draft beam and a connecting beam which is articulated with respect to the draft beam, at least the rotor of the connecting beam located farthest back being equipped with a windrowing deflector. The machine includes a retractable stop for the movement of the connecting beam about its axis of articulation, and a device for shifting the deflector notably with respect to the corresponding rotor. A device controls the stop, which device is actuated by the shifting device. The stop prevents the connecting beam and the corresponding rotor from moving from a first work position into a second work position as long as the deflector can collide with the rotor which precedes it. When the deflector is shifted into a position where the risk of collision is eliminated, the stop is retracted and the change in position is possible.

    Abstract: A windrow turner is described in which a wheeled frame is provided including a forward and a rearward end. A windrow pick-up on the frame adjacent the forward end, and a substantially upright helical auger flight is situated rearwardly adjacent the windrow pick-up. A drive is connected to the auger flight and is selectively operable to rotate the auger flight about an auger axis in a lifting mode such that material engaging the rotating auger flight is lifted upwardly by the auger flight. A guide between the windrow pick-up and auger leads angularly from the windrow pick-up to the auger flight. The auger flight rotates about the auger axis to engage the windrow lifted by the windrow pick-up and progressively inverts the windrow by turning the windrow laterally where a discharge chute on the frame receives and guides the inverted windrow back to the ground surface.

  • Patent number: 5918451
    Abstract: A hay raking machine of the present invention for attachment to a tractor with a single point hitch has a lifting mechanism for lifting the hay raking machine above cut hay laying on the ground while keeping the rake arms substantially level to the ground. The lifting mechanism employs two hydraulic cylinders working in tandem, with one cylinder located at the rear of the machine below the cam assembly for the rake arms, and the other cylinder located at the front of the machine which attaches to the single point hitch. The front cylinder cooperates with an assembly of four hitch arms in a parallelogram configuration for raising and lowering the front of the machine in unison with the rear of the machine. A farmer therefore has control over the height of the hay raking machine and its raking arms both during raking operations and during transport over roads or other potentially damaging surfaces.

  • 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: 4249367
    Abstract: A brush windrower for accumulating brush and trimmings from under orchard trees, in which a main frame extends rearwardly from a tractor which is driven between the tree rows, and a rake bar extends outwardly from the main frame and passes underneath the overhanging branches to gather the brush. The rake bar is pivotally attached to the main frame and a hydraulic cylinder swings the rake bar around the pivot point to move the accumulated brush into the drive middles of the orchard. The rake bar is hinged to permit the rake teeth to tilt, thereby fully releasing the brush. Depth of extension of the rake bar is regulated hydraulically or by adding extensions to the rake bar. The rake bar also can be tilted to sweep evenly across sloping ground.

  • Patent number: 3975892
    Abstract: A haying machine has a plurality of rotary rakes spaced apart transverse to its travel direction. Each rake has a plurality of tines extending through a housing rotatable about an upright axis and each having an inner end secured in a ball rotatable about an element nonrotatable in the housing but axially displaceable therein. The times each have an upper section about which they may be twisted by cam action, and a lower section that normally extends at a right angle to the ground. When the element in which the balls are carried is lifted all the way up control arms on the rake elements ride a cam to orient these elements with respect to the ground with the orbits of adjacent rakes spaced from each other, and when this bearing plate is lowered the control arms are moved out of contact with the cams in the housing and the rake elements are lifted so as to define an orbit of larger diameter that overlaps with the orbit of the neighboring rake.

  • Patent number: 3948028
    Abstract: The disclosure is of an agricultural hay-making machine for both tedding and windrowing, comprising at least two rotors, means mounting said rotors on said machine for rotation, each rotor comprising tool-carrier arms articulatedly connected to cranks which cranks are articulatedly connected between an annular support and push-rods, the push-rods being articulatedly connected to a hub for transposition of the annular support and the tool-carrier arms between two positions of which one is a low swathing position and the other is a higher tedding position.
