Abstract

Abstract A horticulture apparatus for handling plants within a greenhouse, or the like, in which the plants and containers are loaded upon pallets which in turn are loaded upon wheeled carts and moved to supporting racks within a greenhouse. The pallets are then transferred from the carts to the racks. The carts and racks each have parallel roller tracks spaced at a predetermined distance for the pallets to roll upon. The pallets each have cylindrical runners on the bottom thereof in parallel spaced relationship to ride in the parallel spaced tracks of the carts. The pallets can be easily slid from the carts to the support racks and back onto the carts and the carts also have a locking system for preventing the pallets from rolling off the cart tracks during movement of the carts and the cart and rack tracks have arcuate end portions for aligning the pallets when shifting the carts therebetween. The cart frame may also be divided with the top part and cart tracks for the runners to slide in so that a more precise alignment can be had between the cart pallet tracks and the support rack tracks. The carts are made to be spaced uniformly with a plurality of carts pulled by a single vehicle which can stop at marked points for unloading a plurality of pallets onto a plurality of spaced and marked off support racks for each stop of the towing vehicle.
