Abstract
In a harvester wherein the frame is raised relative to ground wheels for roading purposes and such elevation of the frame stretches flotation springs to thereby lift the harvesting header off the ground, the amount of flotation force exerted by the springs on the header can be quickly and easily adjusted by only partially raising the frame and then inserting mechanical stops which prevent retraction of hydraulic lifting cylinders when pressure is relieved therein. By inserting a variable number of such stops in a stack, the flotation force can likewise be adjustably varied.
