ABSTRACT:
An adjustable shearbar apparatus for a forage harvester is disclosed wherein a pair of levers pivotally supported to effect positional adjustments of the shearbar are mounted such that the pivot axis is located in an offset relationship relative to the axis of the shearbar. An upper clamping member detachably connected to a lower support mechanism by a threaded member positioned in line with the shearbar axis to clamp the shearbar therebetween connecting apparatus detachably affixing the shearbar to each of the levers includes a threaded fastener received through an opening extending through each lever and threadably engaged with the shearbar. The connecting apparatus also includes cupped washer assemblies to create a ball joint effect to facilitate the relative movement between the levers and the corresponding fasteners, permitting the shearbar to be moved linearly by a pair of pivotally movable levers.
