  • Patent number: 7712297
    Abstract: A single action hydraulic cylinder is utilized to rise a rake arm from the operating position to the transport position. An elastic mass is provided between the outer body of the hydraulic cylinder and an adjusting device, such as a nut on the stem of the cylinder. When the cylinder is actuated to rise the rake arm, the stem extends out of the cylinder body, thus freeing the elastic mass from the contact with the cylinder outer body. When lowering the rake arm to its operative position, the stem retracts and the elastic mass comes in contact with the cylinder, thereby acting against the retracting action and limiting the downward movement of the rake arm. The elasticity of the elastic mass permits small vertical movements of the rake arm to accommodate unevenness of the ground.

  • Patent number: 7040079
    Abstract: A rake has two side members attached perpendicularly to the rake so as to form an H-shaped frame system. A swivelable wheel is mounted at each corner of the frame. The frame fully stabilizes the rake in a position approximately level with a ground surface as the rake is pulled across the ground by a tractor or other vehicle. The wheels are adjustable both vertically and horizontally by inserting or removing rings on a shaft holding each wheel, and by telescoping parts of the frame into each other. The invention is useful either as a combined rake/stabilizer system, or as a kit for retrofitting existing rakes.

  • Patent number: 6250058
    Abstract: An implement for displacing crop lying on the ground comprising at least one rake member which is driven so as to be rotatable about an upwardly orientated axis and which is provided with a plurality of outwardly extending arms, each of which pivots in upward direction about a pivot axis. Each arm has a pair of outwardly extending tines connected pivotably thereto. The pivotal connections of the arms to the rake wheels and the tines to the arms of each assemble of arms and tines is such that the center of gravity, when the implement is operating, is so disposed that the resultant of the gravitational and centrifugal forces urge the arms and the tines towards the underlying ground. The rake wheels can be folded upwardly about their pivot axes into a transport position wherein the arms are received in a locking device which comprises a resilient member having a recess for receiving each arm. The resilient member may comprise a spring or be composed of an elastic material such as plastic or rubber.

  • Patent number: 5862659
    Abstract: A haymaking machine including at least one windrowing rotor which is articulated to a bearing structure in such a manner that it can pivot about at least one axis which is substantially horizontal and perpendicular to the direction of travel. The at least one rotor can be driven in rotation about a central spindle which is substantially vertical and which is fitted at its lower end with a support equipped with several bearing wheels at least one of which is situated behind the central spindle. The bearing wheel which is situated behind the central spindle of the rotor is connected to an arm of the support which includes a mechanism pressing the bearing wheel against the ground during windrowing work in such a way that it is constantly bearing against the ground and tends to cause the rotor to pivot downward on its front half about the articulation to the bearing structure.

  • Patent number: 5548949
    Abstract: A hay making machine including a carrying structure which can be attached to a tractor such that the carrying structure can travel with the tractor in a forward direction. A substantially vertical support axle is mounted to the carrying structure and supports a rotor having hay making tools. A girder is attached to the support axle. A support structure is articulated to the girder via one substantially vertical pivot spindle positioned forward of the support axle. Two beams, each carrying two carrying wheels, are connected to the support at opposite sides. At curves and turns of the trajectory of the tractor, all of the carrying wheels will pivot together with their beams and the support structure around the pivot spindle. The wheels will therefore be oriented together, without skidding, in the forward direction.

  • Patent number: 5025616
    Abstract: A second hayrake hitch for use with a tractor is disclosed. The hayrake hitch includes a generally U-shaped main frame of size and height to overfit a forward hayrake which is directly connected to the tractor. The main frame includes a main beam and a wheeled rear support bar which is pivotally interconnected relative to the main beam. A second hayrake is connected to a hitch bar secured to the rear support bar to enable the tractor to simultaneously pull the two hayrakes. A hydraulic cylinder extends between the rear support bar and a leg connected to the main beam and hydraulic lines interconnect the cylinder with the hydraulic coupling of the tractor. By hydraulically functioning the cylinder while the tractor is moving, the rear support bar can be pivoted relative to the axis of the main beam to thereby move the rear hayrake to the right or to the left relative to the front hayrake to simultaneously rake two hay windrows or one large combined windrow.
