  • Patent number: 5829940
    Abstract: The bale handler attachment (10) has a frame (26) with a base member (26), an upper member (30) parallel to the base member and a pair of connecting members (32 and 34). A pair of connector assemblies (118 and 120) are connected to the frame (26). A plurality of parallel straight tines (36) are connected to the base member (28). A right shaft (42) and a left shaft (54) are pivotally attached to the frame (26) for pivotal movement about parallel axies that are perpendicular to the axies of the straight tines (36). Arcuate tines (74 and 78) are attached to the right and left shafts (42 and 54) and are pivoted into and out of engagement with bales by a hydraulic cylinder (82). A tiebar (72) connects the upper ends of the shafts (42 and 54) and are pivoted into and out of engagement with bales by a hydraulic cylinder (82). A tie bar (72) connects the upper ends of the shaft.

  • Patent number: 4911491
    Abstract: Bale handling apparatus comprises a main frame including transverse supports and devices mounted on the main frame for picking up bales. These bale pick-up devices comprise a plurality of substantially identical modules which are transversely adjustably mounted on the transverse supports of the main frame so that the number and position of the modules can be varied. The bale pick-up devices each have movable tines which, in an operative position, engage a bale and, in an inoperative position, are retracted clear of a bale, and actuators associated with each respective bale pick-up device operable to move the movable tines thereof to and from the operative position. The actuators of the respective bale pick-up devices are connectable in parallel to a common drive and releasable locking devices are associated with the movable tines of each bale pick-up device for locking the movable tines in the inoperative position.

  • Patent number: 4548535
    Abstract: A pick-up claw apparatus connectible to a farm truck for handling baled material, in particular baled roughage, comprising a carrier beam which when the apparatus is coupled to the truck, is at right angles to the direction of travel of the vehicle. The carrier beam is connected to one or more hydraulically operated claw members, which are connected to the carrier beam in parallel and laterally reciprocating relationship, in a direction at right angles to the beam.

  • Patent number: 4545189
    Abstract: An attachment to a conventional rake having a grasping head pivotally attached to a link which is pivotally attached to the rake head such that an operable clamp is formed, the grasping head being operated by a lever attached to the rake's handle. The pivotal link separates the upper portions of the two heads such that the capacity of the "grasp" is greater than that of conventional rakes with grasping apparatus.

  • Patent number: 4264252
    Abstract: A large crop material bale handler mountable to a prime moving vehicle operable to retrieve, transport and discharge large crop material bales is provided with a main support frame, a traveling load support with material engaging elements fastened to the lower portion thereof, power lifting apparatus to raise and lower the load support, and grappling members pivotally affixed at a pivot point to the load support and extending outwardly and downwardly therefrom. The grappling member has a material engaging end and an opposing end. The pivot point further overlies the plane of the material engaging elements such that when the grappling member is in the engaged position the material engaging end, in combination with the material engaging elements, exerts a grappling and lifting force on a bale.
