The GDX Series Centre Mount Topper is a fully gear driven machine fitted with high speed rotors completed by twin cut swinging blades.
The contra-rotating swinging blades are timed ensuring a stripe free cut. Cutting height is easily adjusted by resetting the skids and castor wheels (optional) at the desired height. Twin cut blades are fitted as standard offering finer cut and better spread than competitors.
The geared blades are timed to prevent blade collisions. To ensure there is no striping, the blades overlap by a minimal 78mm (3”).
The 909HD Topper is a heavier duty version of the 9FTGDX toppers. A new blade design has a quicker flick back reducing shock loading onto gearboxes. This machine is powered by rotor gearboxes through a large horsepower splitter gearbox.
A V rated PTO shaft is supplied as standard for best power transfer. It has an overrun and slip clutch to protect the tractor PTO. Both models are robustly constructed and the free swinging blades ‘twin cut’ system gives precision cutting and greater spreading.
