Work machines, fertilizer opener assemblies for work machines, and methods of operating work machines are disclosed herein. A work machine includes a chassis, a frame, and a fertilizer opener assembly. The frame is coupled to the chassis for movement relative thereto. 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 therein, and a transport position, in which the cutting implement is raised above the soil.

An agitation unit for use in a lawn spreader and other dispensing equipment, and oscillating agitation systems therefor comprising such an agitation unit. The agitation unit includes a hub, an arm extending from the hub, and an extension on the arm configured to project downwardly to an extent relative to the arm and the hub to protrude into, but not through, the outlet passageway of the hopper.

A material discharge system having at least one rotating member disposed within at least one chamber of a holding container. Each rotating member has a central hub with a plurality of arms that extend radially and transversely away from the central hub. The holding container has at least one discharge chamber.

The invention relates to a granule portioning device for an agricultural dispensing machine, comprising a portioning chamber for forming granule portions and a portioning rotor located in the portioning chamber and having at least one contact body, the contact body being designed to move along a circular path during a rotational movement of the portioning rotor and to combine granules located in the portioning chamber into a granule portion.
