The FX-520 heavy duty rotary Cutter is designed primarily for weed, grass, and brush up
to 2" (51 mm) diameter and consists of a center unit with two variable position wings
together having a cutting width of 240 inches (6.10 m). Wing operating angles and
machine cutting height are independently controlled using hydraulic cylinders. A self-
leveling linkage maintains a level cutter at all cutting heights. Power from the tractor PTO
is split at the power divider gearbox and supplied to each of the blade gearboxes. Each
blade gearbox has two free-swinging uplift blades designed to cut grass, corn stalks and
light brush. Free-swinging blades reduce the shock of impact when a stationary object is
hit. Slip clutches are installed on each gearbox for additional protection. Front and rear
discharge shields are included as standard equipment.
