  • Patent number: 10080322
    Abstract: A flexible cultivator implement frame includes a center section and two wing sections. The center section has a main portion and two side portions supported at opposing sides of the main portion for pivotal movement relative to the main portion about respective flexing axes. The flexing axes of the center section are sloped to extend forwardly and laterally outwardly relative to the forward working direction. Each wing section has an inner portion and an outer portion pivotally coupled to the inner portion about a respective flexing axis. The flexing axes of the wing sections are sloped to extend forwardly and laterally inwardly relative to the forward working direction so as to be oriented transversely to the flexing axes of the center section of the frame such that the flexible frame follows ground contours while minimizing undesirable stresses in and twisting of various pivots and frame members.

  • Patent number: 9949432
    Abstract: A vegetation chopping roller for an agricultural land roller implement including a drum body having an outer periphery which is generally cylindrical about a drum axis of rotation and a plurality of protruding mounting flanges upon which chopping blades are mounted using threaded fasteners. A seating surface is fixedly supported in relation to the drum body in association with each blade which receives the inner edge of the associated blade abutted thereon such that the threaded fasteners are substantially isolated from shear forces by the abutment of the blades with the seating surfaces.

  • Patent number: 9839171
    Abstract: A land roller implement includes a main frame section, two intermediate frame sections extending laterally outward from opposing sides of the main frame section in a trailing relationship therewith in a working position, and a pair of outer frame sections extending laterally outward from respective intermediate frame sections in a leading relationship therewith in the working position. The outer frame sections are coupled to the intermediate frame sections by readily removable outer brace portions to reduce the transport width if required. Inner brace members are coupled between the main frame section and the intermediate frame sections by coupling to the outer brace portions at the outer ends and by pivoting on the main frame section about a floating axis which is coaxial with floating movement of the intermediate frame sections relative to the main frame section.

  • Patent number: 9826671
    Abstract: A tillage implement includes a main frame with adjustable toolbar sections thereon which each support respective tillage units thereon for engaging the ground. Each toolbar section has a first end portion coupled to the main frame by a first mounting assembly and an opposing second end portion which is coupled to the main frame by a second mounting assembly. Each one of the first and second mounting assemblies comprises a track and each of the first and second end portions of each toolbar section comprise a follower in mating engagement with the corresponding tracks. The track of the first mounting assembly is oriented closer to the lateral direction than the track of the second mounting assembly such that each toolbar section is pivotal about a respective upright axis generally at the first end portion when the toolbar section is displaced in the forward working direction at the second end portion.

  • Patent number: 9763378
    Abstract: In a winged agricultural implement having two wing frame sections pivotal relative to a center frame section between a laterally extending working position and a rearward trailing transport position, two brace members are pivotally supported on the center frame section to selectively retain and support the wing frame sections in the working position. A hydraulic actuator pivots each brace member between a latched position and a released position relative to the wing frame section. A biasing linkage is provided in series with each hydraulic actuator to provide positive pressure to retain the brace member in a latched position as the wing frame section pivotally floats relative to the center frame section during movement across an agricultural field in a forward working direction.

  • Patent number: 9408338
    Abstract: In a disc assembly for supporting a ground engaging disc on a respective support arm of a vertical tillage implement, the disc supporting hub has an annular body rotatably supported on a shaft. The outer end of the annular body is enclosed by a cap and the inner end of the annular body is enclosed by an end plate fixed on the shaft relative to which the annular body is rotated. First and second annular flanges on the inner end of the annular body receive a tongue portion of the end plate therein so as to define a sinuous, narrow clearance gap where the annular body of the hub and the end plate of the shaft are in a non-contacting, rotatable relationship with one another. The sinuous, narrow clearance gap minimizes penetration of soil and residue therethrough to the interior of the hub where bearings are located.

  • Patent number: 9155240
    Abstract: A tillage implement includes a main frame with adjustable toolbar sections thereon which each support respective tillage units thereon for engaging the ground. According to one aspect of the invention, the toolbar sections are angularly adjustable about a pivot head at one end thereof while also being slidable in a longitudinal direction of the toolbar section to maintain alignment of the tillage units. The pivot head is elongate in a direction transverse to the toolbar section to resist moments applied to the toolbar section by the tillage units engaging the ground while the toolbar section remains adjustable. In another aspect of the invention, the tillage units each comprise a trailing arm supporting the respective coulter disks thereon. The trailing arm is pivoted between two side plates fixed to the toolbar section and biased downward by a spring enclosed between the side plates to resist debris catching on the spring.

  • Patent number: 8684649
    Abstract: A grain cart includes front wheels steerable about respective upright and rearwardly inclined steering axes arranged in a trailing self-steering configuration and rear wheel assemblies which are fixed in a forward working direction. The front wheel assemblies are fixed to the main frame of the cart except for the pivotal movement about the steering axes. The rear wheel assemblies are supported on a rear axle support member coupled by a rear suspension to the main frame so as to be arranged for rocking movement about a forward longitudinal axis. The grain cart optionally incorporates a load scale integrally into the main frame, as well as a hitch arm actuator to transfer of some of the load from the grain cart wheels to the towing vehicle by actuating the hitch arm to pivot the hitch arm downward relative to the main frame.

  • Publication number: 20100278621
    Abstract: A bulk material container suitable for handling with a pallet mover includes a hopper portion which tapers downwardly to a discharge gate which is in an upright orientation offset to one side of the container. When several containers are supported on a flat deck vehicle or trailer, the gates of all of the containers can be oriented to discharge to the sides of the deck. A discharge apparatus supported on the deck comprises a track supporting a discharge conveyor for displacement along the sides of the deck such that an inlet hopper of the conveyor can be aligned with respective ones of the side discharging gates of the containers supported on the deck.
