  • Patent number: 7823372
    Abstract: A mower-conditioner is equipped with a double windrow attachment comprising a longitudinal conveyor which receives crop delivered rearwardly by a rotary conditioner. A side conveyor is located rearward of the longitudinal conveyor and is mounted for movement between a lowered operating position, wherein it is positioned for receiving crop conveyed rearwardly by the longitudinal conveyor, and a raised inoperative position wherein it permits the rearwardly conveyed crop to freely fall to the ground. The longitudinal conveyor is a roller conveyor with the rollers axes in a first embodiment comprising three sets of right- and left-hand rollers with the rollers of each set being skewed relative to a line extending perpendicular to a forward direction of the mower conditioner such that the axes of each set of rollers diverge rearwardly. In a second embodiment the rollers of each set are skewed such that their axes diverge forwardly.

  • Publication number: 20090320432
    Abstract: A windrow merger lift mechanism having on a pair of rotational axes, skewed with respect to each other, to manipulate a merger apparatus between working and non-working positions. When the merger apparatus is in a first, or working position, the lift mechanism positions it to receive crop material from the conditioner rolls with minimal losses. When the merger apparatus is in a second, or non-working position, the lift mechanism positions the merger apparatus to allow crop material to be discharged from the header/conditioner with the same efficiency as a windrower having no installed merger attachment. The skewed axes of the merger lift mechanism optimize the merger position in both the working and non-working positions by moving the merger apparatus in four distinct, but related degrees of motion as the merger apparatus is moved between the positions.

  • Publication number: 20090313964
    Abstract: A floating swathgate for a cutting and conditioning header for a frame-supported tractor in which the angular attitude of the swathgate relative to an airborne stream of crop material being ejected from conditioner apparatus is varied as the header moves vertically with respect to the tractor to optimally direct the crop material toward a rearwardly disposed crop merger conveyor. As the header moves vertically, changes in the angular attitude of the swathgate direct the airborne crop material to generally the same location on the merger conveyor to minimize crop losses that typically occur with a fixed swathgate when the crop trajectory varies directly with the header vertical movement.

  • Publication number: 20010045087
    Abstract: A pull-type mower-conditioner has a windrow grouper mounted to its main frame by a mounting frame that is swingable between lowered working and raised non-working positions. The grouper includes a conveying arrangement defined in part by a belt conveyor mounted to the mounting frame for free pivotal movement, between angularly spaced stops, about a transverse horizontal axis. When the mounting frame is in its working position, the crop-receiving surface of the conveyor is inclined at a slight angle downward toward the rear of the mower-conditioner with gravity holding the conveyor in position against one of the stops. When the mounting frame is in its non-working position, gravity holds the conveyor in a position rotated against the other of the stops, the crop-receiving surface then being almost vertical so that the grouper is almost within the length of the mower-conditioner.

  • Patent number: 6145289
    Abstract: A mower for harvesting crop includes windrow forming housing where crop is discharged after being cut. A windrow grouper attachment includes a crop conveyor attached to the main frame of the mower by a vertically swingable support which is selectively disposable in a lowered working position where it intercepts crop exiting the windrow forming housing and transfers it side ways and in a raised non-use position wherein it permits crop exiting from the mower to be deposited into a windrow directly behind the mower. The vertically swingable support for the crop conveyor is mounted to a slide that is in turn mounted for shifting laterally on a transverse beam of the mower main frame. By selectively manipulating the conveyor among its working, non-use and shifted positions, it is possible to deposit three windrows alongside each other for being subsequently picked up together for processing by another machine, such as an ensilage harvester, for example.

  • Patent number: 5930988
    Abstract: The swathboard of a windrower can be remotely adjusted from the tractor seat and on-the-go using an electromechanical actuator or other remotely operated actuating device. When the swathboard is adjusted to its fully raised position, the stream of crop materials issuing from the conditioner rolls bypasses the swathboard and engages the forming shields to be converged into a windrow having a width determined by the outlet formed between the rear ends of the shields. At the other extreme, when the swathboard is fully lowered, the stream impinges against the swathboard and drops to the ground in a wide swath without ever engaging the forming shields. In any one of a number of intermediate positions, the swathboard can be used by the operator to deflect the stream to engage wider or narrower portions of the forming shields, thus controlling the width of the windrow.
