Abstract: A planter is moved through a field to place two rows of four plants on the top of a planting bed between adjacent irrigation furrows. Plants ready for transplant are disposed in trays within polymerized cast soil plugs. Each plug is disposed within the tray in a hole. Each tray has rows and columns of plant receiving holes extending through each tray. The planter carrying the plugs moves in increments and sets the planter mechanism in a stationary position over the top of the planting bed prior to plug planting. The tray carrying the transplants is registered horizontally and vertically to a plug receiving cylinder by respective cams and a supporting chain. Upon registry, polymer plugs containing sprouted plants therein are ejected, typically eight at a time, by ejecting fingers penetrating the plant receiving holes. Ejection occurs with the plants horizontally disposed into receiving concavities defined within a rotating cylinder.

Abstract: A planter is moved through a field to place two rows of four plants on the top of a planting bed between adjacent irrigation furrows. The tray carrying the transplants is registered horizontally and vertically to a plug receiving cylinder by respective cams and a supporting chain. Upon registry, polymer plugs containing sprouted plants therein are ejected, typically eight at a time, by ejecting fingers penetrating the plant receiving holes. Ejection occurs with the plants horizontally disposed into receiving concavities defined within a rotating cylinder. Rotation of the cylinder drops the ejected plants into receiving funnels, one for each plant. Plant downward travel halts at a reciprocating plate. Insertion of the plug into the ground begins with penetration of the ground by a dibble spike followed by circumscribing penetration of a dibble tube around the spike.

Abstract: A carton supporting platform mounted on a vehicle for rotative movement about a vertically extending axis. Rigid side walls are provided on two opposite sides of the platform and are movable between an upright position and an outwardly diverging retracted position. In the upright position the side walls retain parallelepiped produce cartons placed on the platform in a unitized entity during transportation of the same. In order to unload the unitized entity from the carton supporting platform without adversely affecting the integrity of the unitized entity, the platform is pivoted 90.degree. to permit access by a fork lift truck from the side of the vehicle and the side walls are pivoted outward to release the unitized entity. Mechanism for locking the rotative position of the platform and for moving the side walls is provided. Also provided is a method for effecting formation of the unitized entity and for transporting the same without adversely affecting the integrity of the unitized entity.

Abstract: The flatbed of a truck that is geared for traverse of an agricultural field is provided with at least one pair of longitudinally extending tracks. Disposed in the tracks for rolling movement thereon is a plurality of roller supported assemblies which are adapted to support pallets of more or less conventional form. The roller supported assemblies are arranged to retain a plurality of pallets consolidated into a single group. An over-the-road carrier, such as a trailer or a semi-trailer, has a similar pair of longitudinally extending slots so that after the agricultural truck is loaded during transverse of the field, it can be backed adjacent to the carrier so that the tracks on the vehicle and the tracks on the carrier are in registry. A winch carries a cable which is attachable to the grouped pallets to effect transfer of the pallets from the truck bed to the carrier bed.

Abstract: A method and apparatus for harvesting and processing head lettuce wherein the lettuce is shredded immediately upon harvesting and before deterioration occurs. The shredded lettuce is retained in an insulated or refrigerated enclosure and then promptly transported to a mobile processing trailer where it is further cleaned and chilled and finally packaged for shipment. The practice of the method and apparatus permits the lettuce to be on its way to the consumer on the same day that it is harvested from the field.A method and apparatus for simultaneously chilling, washing and adding preservatives to the chilled lettuce in a continuous fashion. A mobile enclosure embodying the apparatus and adapted to perform the method wherein the lettuce is maintained at a reduced temperature throughout all stages of processing.

Abstract: A palletizing system for a plurality of generally parallelepiped cartons containing crushable products such as heads of lettuce. A pallet dimensioned to receive thereon a plurality of uniform size cartons in a rectangular pattern whereby orthogonal vertical confronting zones are formed intermediate the cartons. Two or more thin elongate compression resistant members and means for supporting the members on the pallet and within the zones. A rigid plate substantially congruent to the pallet for placement in bearing relation at the upper extremities of the compression resistant members so that the load from a plurality of cartons stacked on top of the plate will be transferred to the pallet and will not unduly compress or damage the cartons disposed below the plate.
