Abstract: A stackable pallet system comprises a plurality of pallets used for holding and transporting various items, including potted plants such as potted trees, flowers, bushes, etc. When the pallets are to be stacked, two pairs of spacer pipes can be used on a first pallet extending upwardly therefrom. Two elongated saddles are then coupled, one to each pair of spacer pipes, such that the saddles extend between and unite the upper ends of the pairs of spacer pipes. The saddles comprise an upwardly facing, shallow channel which is sized to be slightly larger than at least a portion of the fork pockets contained on the pallet. A second pallet can be lowered down onto a first pallet with the fork pockets, or at least a portion of the fork pockets, being received in the saddle channels. Various containment rings can be coupled to the pipes, in place of or in addition to the saddles, to allow longer trees to be carried on the pallets or to allow double stacking of potted plants on a single pallet.

Abstract: A dump wagon for transporting potted plants from one location to another and for unloading the potted plants. The dump wagon includes a wagon bed that tilts between a horizontal transport position and a tilted or inclined unloading position. A pusher at one end of the wagon bed is movable towards the other end of the wagon bed to push potted plants off the wagon as the wagon is slowly moved forwardly. The pusher is chain driven and automatically disengages the chains when the pusher reaches the other end of the wagon bed and the unloading operation is complete. Side rails prevent the potted plants from falling off the sides of the wagon, the side rails being movable out of the way for the purpose of loading the dump wagon.
