Abstract: A corn snapping header for a forage harvester is provided with corn snapping units of the snapping plate type which are disposed with their crop passages converging to a single rear outlet. A single transverse drive line with flexible drive means is provided to drive the snapping units.

Abstract: An adjustable drawbar, which is capable of longitudinal adjustment to accommodate implements having power lines of different lengths, having a hitch pin hole at one end to permit attachment of an implement and a plurality of bores through its other end. A bracket having aligned apertures is affixed to the tractor and supports the other end of the drawbar. A pin carried by a bell crank assembly mounted on the tractor is movable by means of a control rod between an adjust position in which the pin is extracted from at least one of said apertures and a hold position in which the pin extends through both apertures and an aligned one of the plurality of bores.

Abstract: A corn snapping header frame having transverse beam assemblies pivotally mounted at each end of a transverse main frame, the transverse beams being forwardly offset from the frame and having corn snapping units mounted thereon.

Abstract: Gathering unit attaching apparatus is provided for a forage harvester of the type having a basic processing unit and a crop gathering unit which articulates in a vertical plane relative thereto. The attaching apparatus includes an attaching yoke pivotally mounted on a fixed transverse axis provided on the basic unit in proximity of the feed rolls. The attaching yoke provides a movable auxiliary axis about which the gathering unit pivots during the attaching process and securing elements for locking the gathering unit to the yoke for field operation. Apparatus is provided on the basic unit for pivoting the yoke about the fixed axis between a lowered generally forwardly extending pickup position and raised operating and transport positions.

Abstract: A forage harvester of the type having a rotary reel cutterhead and a feed roll mechanism for feeding crops to the cutterhead is provided with improved drive means for the feed roll mechanism including a forward chain drive arrangement incorporating intermediate shafts and an electromagnetic clutch and a reverse chain drive arrangement incorporating a second electromagnetic clutch, both drive arrangements being driven from the cutterhead drive and driving a common output shaft operatively connected with the feed roll mechanism. An electrical remote control switch operates the electromagnetic clutches for mutually exclusive engagement, or with neither clutch engaged, to produce remotely controlled shifting of the mechanism between forward, idle and reverse drives.
