  • Cutting angle adjustment mechanism for crop harvesting machines
    Patent number: 4473993
    Abstract: A mechanism for changing the cutting angle of the cutterbar on a crop harvestng machine, such as a mower-conditioner or windrower, relative to the ground is disclosed wherein the cutting angle can be changed while the harvesting machine is being operated. This on-the-go adjustment mechanism includes a hydraulic cylinder positioned as the top link between the frame of the harvesting machine and the header in which the cutterbar is mounted. Changes in the length of the hydraulic cylinder affect a pivotal movement of the header about the lower links interconnecting the frame and the header to change the angle of the cutterbar relative to the ground.
