Abstract
Work machines, fertilizer opener assemblies for work machines, and methods of operating work machines are disclosed. A work machine includes a chassis, a frame, and a fertilizer opener assembly. The frame is coupled to the chassis for movement relative to the chassis. The fertilizer opener assembly is coupled to the frame to selectively form trenches in the soil for the deposition of fertilizer. The fertilizer opener assembly includes an actuator that is extendable and retractable to vary a length of the actuator and a cutting implement coupled to the actuator. Operation of the actuator drives movement of the cutting implement between a cutting position, in which the cutting implement makes contact with the soil to form trenches in the soil, and a transport position, in which the cutting implement is raised above the soil.
