Abstract: One or more techniques and/or systems are disclosed for leveling a rotary cutter that includes a center cutting portion, a first cutting wing pivotally coupled to the center cutting portion, a second cutting wing pivotally coupled to the center cutting portion, and an actuator system having a center leveling sub-system, a first wing leveling sub-system, and a second wing leveling sub-system. The actuator system is configured to synchronously adjust the height of the center cutting portion, the first cutting wing, and the second cutting wing. The first wing leveling sub-system is configured to adjust the height of the first cutting wing independent from the center cutting portion and the second cutting wing, and the second wing leveling sub-system is configured to adjust the height of the second cutting wing independent from the center cutting portion and the first cutting wing.

Abstract: An actuator assembly having an end guide with a first end and a second end, the end guide defining an axis passing through the first and second end, a rod having an outer surface, the rod being movable along the axis through the end guide, a wiper disposed outwardly of the rod and within the end guide, a scraper disposed outwardly of the rod and within the end guide and spaced axially from the wiper towards the second end, a cavity defined between the wiper, the scraper, the outer surface of the rod, and the end guide, and an orifice defined in the end guide between the wiper and the scraper, the orifice defining a flow path for a lubricating fluid to flow into the cavity, wherein, the wiper and the scraper are disposed in contact with the outer surface of the rod for removing debris therefrom.
