ABSTRACT:
A method and apparatus for harvesting and stacking sod is disclosed. A reciprocating cutter bar cuts strips of sod while a vertically moveable blade cuts these strips into blocks of the desired length. The blocks of sod are guided onto an inclined conveyor which carries them to the top of a sod stacker having a plurality of normally closed trap doors. The blocks of sod are guided onto the stacker in alignment with the trap doors and are moved across the upper surfaces of the doors by means of sod advancing chains until they are in position to be stacked. A trip mechanism responds to the position of the sod blocks to release the trap doors, causing the blocks to drop downwardly through the doors onto a pallet supported on a fork lift immediately below the trap doors. As the sod falls through the trap doors, a hydraulic lift recloses them for receipt of the next block. The pallet is adjustable to maintain the desired spacing between the top of the stack of sod and the trap doors and is removed from the stacker when full. In a preferred embodiment, the apparatus cuts and stacks three adjacent strips of sod, and means are provided at the stacker for securing the resulting three stacks together to retain them in position on the pallet.
