  • Patent number: 9220188
    Abstract: A latch to secure folding implements in a transport configuration. The latch is constructed so as to permit selective disengaging of the latch to allow the folding implement to be configured for operation. A latching mechanism with a pivoting portion engages a crossbar in latching. One of the latching mechanism or pivoting portion is suspended on an extension bar which is cantilevered and suspended from either a main frame or a folding arm. The latching system tolerates misalignment of the main frame and folding arms through the suspension system.

  • Publication number: 20120103208
    Abstract: A baler with a pickup and a baling chamber with an inlet, the bale forming chamber having a first and second side panel, a plurality rollers rotatably disposed respectively about parallel axes. A bale edge engaging member is rotatably attached to the frame about an axis of rotation substantially parallel to said axes of the rollers, the bale edge engaging member being disposed adjacent an inside portion of one of the side panels in overlapping arrangement with a bale being formed in the baling chamber at least at times when a bale is being formed. The bale edge engaging member is spaced from the inlet to the bale forming chamber so as to not impede material entering the bale forming chamber from a pickup. Alternate embodiments have the rotatable bale edge engaging member/disc on a fixed axis adjacent the baling chamber when the bale is almost completed.
