Tractor-Mounted Fenceline Mowers and Trimmers cut underneath one's fenceline (as driver travels parallel to it), keeping it free of overgrown grass and weeds. Attached to the tractor's three-point hitch and using its PTO and hydraulic lift, these devices automatically maneuver around each fence post (or any other obstacle) then reposition themselves (i.e., snap back) once past it. Both the "mower type" (rotating blades) and the "trimmer type" (thick cutting cords) mount/operate/perform similarly and are also used for grass/weed-clearing at ditch banks, in tree orchards, around buildings, etc.
