The truck-mounted, adjustable platform shown in photos was developed for use in spraying, pruning, and harvesting of small-scale plots. It might also be adapted to a number of other farm operations. A hundred-gallon spray rig can be carried in the bed of the truck plus a generator for electricity or a pump to supply hydraulic pressure. This low-cost unit was designed for a half-ton pickup and with slight modifications will fit almost all makes. It also can be modified for use on tractors or trailers.
