SUSPENDED FLOATING SPRAYER BOOM

摘要

An applicator boom apparatus comprises an applicator boom extending laterall y from a vehicle, and pivotally attached to the vehicle such that the boom can pivot up and down with respect to the vehicle. A gauge member is adapted to ride along a surface of the ground and support an outer portion of the boom such that the boom moves up and down wi th the gauge member as the gauge member rides along the ground. A bias element is attache d to the vehicle and exerts an upward force on the boom such that a downward force exerted on the gauge member by the boom is reduced. The bias element can be conveniently provided by a hydraulic cylinder supplied from an active hydraulic source such that the cylinder and attached boom can float with changes in the terrain. A kit is provided to improve performance of prior art applicators.
