Abstract
A harvester platform is suspended from the implement main frame by a linkage including a pair of lower transversely spaced links each having rear and front ends respectively pivotally attached to the main frame and the platform. Associated with each lower suspension link is a hydraulic float cylinder coupled between the main frame and the associated link so as to exert a lifting force on the link. The amount of lifting force exerted by each float cylinder may be varied by adjusting the location of the anchor pin connecting the cylinder to the main frame through means of an adjustable bracket that carries the anchor pin. Side-to-side float balance of the platform is achieved through properly adjusting the anchor pin locations so that the float cylinder at the heavier end of the platform exerts a greater lifting force than the float cylinder at the lighter end of the platform.
