  • Patent number: 11234432
    Abstract: Folding spray implements and agricultural work vehicle equipped with folding spray implements are provided. In embodiments, the folding spray implement includes a centerframe assembly, boom assemblies mounted to opposing sides of the centerframe assembly, and an actuation system coupled to the centerframe and boom assemblies. The boom assemblies include, in turn, inner wings pivotally joined to the centerframe assembly for rotation about frame-to-wing fold joints, as well as outer wings pivotally joined to the inner wings for rotation about wing-to-wing fold joints.
    Type: Grant
    Filed: July 10, 2019
    Date of Patent: February 1, 2022
    Assignee: DEERE & COMPANY

  • Patent number: 5609523
    Abstract: A telescoping cotton harvester basket includes latches adjacent the four corners of the basket and spring loaded to automatically lock a basket extension in position as the extension moves from a retracted storage position to an extended harvest position. The latches are connected by fore-and-aft extending linkages and a transverse shaft for operation in unison from a single location to release the basket extension for movement back to the retracted storage position. A reset mechanism automatically moves the latches to a closed or locking position in preparation for the subsequent movement of the basket back to the extended harvest position so that only one manual activation of the latches is required for a complete basket extension-retraction cycle.

  • Patent number: 5407390
    Abstract: A cotton basket is pivotally connected to a harvester frame for rocking about a fore-and-aft extending axis located a substantial distance above the basket floor on the side of the basket opposite the dump side. Simple single beam mast structures at the front and rear ends of the basket replace more conventional and massive multi-element mast structures typical in previously available harvesters. Cylinders connected near the center of gravity at the basket ends rock the basket upwardly and outwardly about the axis to a position above the wagon or module builder. The pivot angle through which the basket is rocked is substantially less than 30 degrees for minimal shifting of the center of gravity during dumping. Dump height is controlled by cylinder extension. The main conveyor floor has front and rear conveyors which move cotton to an independently controlled conveyor built into a fold-down door. The door conveyor can be emptied independently of the main conveyor operation for a partial dump.
