  • Patent number: 4172500
    Abstract: Immediately rearwardly of the peanut combine pickup head, a plowshare supported by gage wheels delivers fallen loose peanuts to an inclined conveyor having rearwardly moving paddle bars which sweep the loose peanuts rearwardly and upwardly over a rod grate through which small debris is sifted. At the rear of the conveyor and grate, the loose peanuts are delivered into a cross auger having a trough formed by additional grate bars and from this auger trough the loose peanuts and remaining lightweight debris are blown pneumatically into the combine for final cleaning and separation. Heavier debris in the auger trough is forced through a spring loaded trap door at one end of the trough by the action of the auger.

  • Patent number: 4015410
    Abstract: A floating cylinder or roller attachment for mobile pick-up balers is positioned slightly ahead of the rotating pick-up teeth and is held somewhat above the ground while being freely rotatable on a cross shaft. The cross shaft is held on a pair of support arms which may swing vertically and whose rear ends are pivoted to the top of the auger hood. Intermediate support for the pivoted cylinder support arms is afforded by an existing transverse bar on the baler. The attachment prevents hay or other crops in a windrow from being rolled or kicked forwardly by the baler pick-up mechanism and thus prevents loss of hay while promoting an even flow into the feed auger of the baler.
