Tractor spray cylinder attachment

摘要

A spray attachment for a tractor to disperse and spray liquid pesticides, fertilizers, or the like. The spray attachment includes a cylindrical tank having a pair of wheels secured to each end thereof. Each wheel includes a series of pistons spaced about its circumference in communication with the interior of each wheel and the tank for sequentially pressurizing the tank as each wheel rotates into contact with the ground surface. Liquid from the interior of the tank and each wheel is dispensed under pressure in a spray through a series of spaced orifices extending about the side wall of each wheel adjacent its outer periphery.
