Disc mower upgrade

Kuhn disc mowers are getting an upgrade. Kuhn disc mowers are getting an upgrade.

The mowers will soon start rolling so it’s timely for CB Norwood Distributors to announce upgrades to its Kuhn disc mowers.

The new GMD 240, 280 and 310 units, with 6, 7 and 8 discs respectively, replaces the GMD600-800 GII series. 

It has a new linkage frame claimed 70% stronger than the previous version, and more adaptable to a larger number of wheel spacings and tyre widths. This takes the form of a hexagonal sliding bar at the lower link point. There is also a strengthening of the link between the bevel gearbox, where drive enters, and the cutter-bar unit.

The 100 series cutter-bar has a low profile disc, with two blades for a clean cut, and can be specified with standard bolt up blades, fast-fit for quick blade changes or the heavy duty system suited to arduous use particularly in stony conditions. 

The cutter-bar has the maker’s Protectadrive system which upon impact allows the shaft to shear along a pre-machined groove, protecting the main drive components and allowing quick replacement.

The mower has adjustable suspension by means of a pressurised hydraulic cylinder, and adaptability to deal with slopes up to 35 degrees above, and 25 degrees below horizontal, while ensuring the ground pressured is maintained to avoid ground damage, and to ensure quick re-growth

The new series also has a reinforced guard frame to promote good crop flow and increased forward speed, and uses a rotary swath former on the outer edge of the bar to form a manageable swath for following operations.
