  • Patent number: 4368003
    Abstract: A front foldable farm implement and hopper-feeding auger comprising an elongated hopper-supporting frame in three separable sections in end-to-end relation. A drawbar is secured to and transversely extends from the central portion of the intermediate section. First means pivotally connects the opposite ends of this central portion to the adjacent ends of the outboard sections, respectively, whereby the outboard sections may be pivoted between a first position in which the three sections are aligned and a second position in which the outboard sections are generally parallel to the drawbar. A plurality of hoppers is carried by the sections. An elongated tubular conveyor in two separable length portions is carried by the two outboard sections, respectively, these length portions being disposed above and in feeding registry with the hoppers. Further, the conveyor extends parallel to the frame sections when the outboard sections are in the first position.

  • Patent number: 4137852
    Abstract: A forwardly foldable agricultural planter includes a hitch shiftable as wing sectons are moved between transport and operational configurations. Rigid link tow bars pivot about centrally positioned pivots permitting the hitch to be horizontally shifted between transport and operational positions to thereby realize positive drawn implement control in both configurations. A telescoping drawbar provides further implement support and control and either manual or automatic latching mechanisms can be provided to secure the folded wing sections in position.

  • Patent number: 4137853
    Abstract: A pull type folding grain drill driven by the gauge wheels including pivoting legs carrying the gauge wheels which drive a clutch shaft through a first chain and sprocket drive, the clutch shaft axis being offset from the pivoting leg axis. A second chain and sprocket drive between the dispensing seed shaft and the clutch shaft including an idler pulley having cam means on the end thereof for disengaging a clutch on the clutch shaft when the pivoting legs are rotated to lift the planter out of the ground in the transport position.
