Abstract
A shank mounting arrangement for a disk hiller or similar implement which provides simple and precise angular adjustment of the shank independently of vertical adjustment. An upright slotted tube is fixed to a support beam and an upright apertured shank is slidably received in the tube. An adjustable collar including a plurality of holes adapted for alignment with the slots in the upright tube is mounted for rotation with respect to the upright tube, and a pin is inserted through the holes, slot and an aperture in the shank for retaining the shank in a preselected one of a plurality of vertical positions relative to the support beam. The collar may be rotated independently of vertical adjustment to change the angle of the shank.
