Kuhn unveils 14.5m mower for high HP harvesters
With most forage harvester manufacturers offering machines touching 1000hp, the logistics puzzle has always been ‘dropping” grass and pulling into a swath big enough to feed the “beast”.
Developed through farmer testing in paddocks around the world, the cutter-bar design has an even lower profile, while retaining the performance and reliability features of the original Optidisc design.
The design is said to create a smooth, clean cut with minimal ash incorporation due to a very flat cutter-bar angle even at low cutting heights. Additionally, differential disc spacing utilises narrower spacing at the diverging discs for extra knife overlap to create a clean cut even when the grass is short or light. Wider spacing of the converging discs provides more space for the crop to pass from the cutting area; improving the cut quality, while free-rotating Fast-Fit knives also help enhance cutting quality and provide longer knife life.
Reliability is retained through Kuhn’s patented Protectadrive disc bearing stations, that upon striking major obstacles, are designed to shear outside the gear case protecting the components within the cutter-bar.
The equal sized gears allow maximum power transfer with even torque loads across the full cutting width. Maintenance and downtime are minimized with a lubricated-for-life design requiring no routine oil changes.
