ABSTRACT:
A potato or other root crop harvester having a shock absorbing primary bed is disclosed. The primary bed is held in normal digging position by high pressure fluid cylinders. A shock to the shovels attached to the forward edge of the primary bed causes the fluid pressure to rise within the cylinders, thereby exceeding a relief valve setting and allowing the fluid to discharge from the cylinders to permit the primary bed to move rearwardly, absorbing the shock and preventing damage to the harvester. A further unique feature of the potato harvester is the presence of three shovels attached to the primary bed to harvest three rows simultaneously. The primary bed discharges tubers onto a secondary bed which transports them to lateral transport means to discharge them into trucks or other carriers. A devining chain encompasses the secondary bed, allowing potatoes to fall through onto the secondary bed while carrying vines to the rear of the harvester to discharge them.
