ABSTRACT:
The present machine peels strips of sod from the ground and conveys them upwardly and rearwardly to power driven horizontal rollers. Cutting knives just ahead of these rollers cut the sod strips transversely into pieces of a predetermined length. At the same time, a horizontal platform is raised below the rollers, and upwardly projecting fingers on this platform pass between the rollers and lift the cut pieces of sod off the rollers. During the up and down movement of the platform the oncoming sod strips are held back on the conveyor. A transfer apparatus moves horizontally between a position overlying the rollers, where it receives the sod pieces after they are lifted off the rollers, and a stacking location at one side of the rollers, where it releases the sod pieces to drop by gravity into neighboring stacks. The timing of such release is varied periodically so that the stacks of sod pieces will overlap laterally at intervals.
