The shaft has flanges disposed so that the movable frame may be raised or lowered relatively rela-tively to the stationary frame of a crank secured to the shaft. Journaled in bearings in the movable frame Is a longitudinally extending shaft, to the outer end of which Is secured a disk or colter to be ground, the longitudinal Holder for Disks and Colters. shaft being driven by gearing, which connects a transverse shaft, having a crank, with the longitudinal shaft. |
