Abstract
U-shaped cushions, also known as shanks or spring members, resiliently support a gang of disks on the frame of a disk harrow. The agricultural disk cushion is manufactured from a round section of raw material which is lighter and more resistant to torsion related failure than traditional rectangular section shanks. Two leg portions are each tapered to have flat surfaces on opposite sides for flush fitting with mounting elements, while a central portion connecting them remains circular in cross section. The round cross section in this critical area can withstand severe omni-directional loading, as its resistance is equal in all directions The spring rate the leg portions of the disk cushion can be tailored individually to meet the requirements of the application.
