Abstract

A crop sprayer includes a number of wheels, a chassis supported by the number of wheels, a boom frame supported by the chassis, and a boom arm segment. The boom arm segment operates in a first mode of operation in which the boom arm segment is maintained at a fixed position relative to the boom frame and a second mode of operation in which the boom arm segment is allowed to freely pivot relative to the boom frame. The crop sprayer further includes an actuator supported on the boom arm segment. The actuator is movable between a pivot-preventing position and a pivot-enabling position. The boom arm segment operates in the first mode of operation when the actuator is positioned in the pivot-preventing position. Movement of the actuator from the pivot-preventing position to the pivot-enabling position causes the boom arm segment to operate in the second mode of operation. A method of preventing damage to a boom arm assembly during a collision between the boom arm assembly and an obstruction is also disclosed.
