Self-propelled agricultural machine, e.g. sprayer for spreading fertilizer, in slope or irregular ground, has slave jack that is actuated based on plate of the chassis to maintain parallelism of spray boom relative to slope of ground

摘要

Self-propelled agricultural machine has a spray boom that is transversely disposed to direction of progression of the machine and that then remains parallel to slope of the ground during work of the machine. The boom is suspended to a chassis (1) and its orientation is modifiable by a slave jack (32) that corrects inclination of the boom. The jack is actuated based on a plate of the chassis to maintain parallelism of the boom with respect to the slope.
