  • Energy absorber for hubs of agricultural disc drive
    Patent number: 6604347
    Abstract: A disc cutterbar with at least one cutterhead having a two-piece mounting hub, one piece rotatably driven and the other supporting a knife for severing standing crop material, with an epoxy layer bonding the two pieces together and forming a shear device therebetween. A brake is associated with the knife-supporting piece whereby upon failure of the shear device, the knife-supporting piece is stopped from rotating within one revolution. The brake includes upper and lower locking blocks having generally mating teeth. Upon failure of the shear device, the teeth of the upper and lower locking blocks engage, thereby stopping the rotation of the mounting hub.
