Round drums do not transport well. That is why KUHN uses drums with two flat sides for optimal crop transport without the risk of blockage. Movement of the crop has an impact on the mowing quality. The exchangeable transport strips enable you to adjust the amount of strips to the conditions and protect the drums from wear.
The continuous cutting height adjustment on top of the mower, with an increased range of up to 45 mm, allows you to set the optimum cutting height in changing conditions in an easy and safe way. This allows you for example to mow a little higher in the autumn in order to reduce soil contamination in your forage.
The freely rotating saucers have a major advantage. In uneven ground conditions, the saucer ‘rotates’ over the ground rather than sliding, thus protecting the stubble and reducing PTO power requirement. The positive effects of reduced crop contamination will be particularly noticeable on sensitive soils such as boggy land.
The typical PZ ‘big & small’ what is this? knife plate layout provides a narrow swath, secured via the standard swath discs. This narrow swath fits within the tractors tyres and prevents damage and contamination of the cut crop. Another advantage of this typical layout is the very low power requirement thanks to the large throughput opening between the drums.
The PZ 2721 F and 3021 F models are equipped with a set of swath discs as standard. An extra pair of swath discs are available on request. This allows you to deposit the grass in an optimum swath for any following machinery.
Using the special hook shaped tool, you can push the knife holder down and simply replace the knifes. A quick and secure system which is not compromised by crop build-up.
Damage to the side covers is now a thing of the past. The KUHN FLEXPROTECT flexible side covers add a new dimension to mowing with their design made of polythene. On encountering any obstacles, the material of the side cover bends, without breaking or damaging the mower. The material then returns back to its original shape. This is especially useful when mowing around poles or along around the edges of a field.
Optionally available are hydraulically foldable side covers, which offer a high level of operator comfort.
The foldable front and side protective covers can be lifted upwards, convenient for daily inspection and blade exchange.
The front cover can be folded 90° upwards, allowing easy access to the blades. This is perfect for daily inspections and mower maintenance.
The reliable V-belt driveline protection ensures an easy start-up of the machine. The V-belt drive with large bearings and shaft can transfer 30 % more power than previous models. This makes the mowers suitable for both regular and larger tractors.
Robust drive units with spiral-toothed gears give maximum power transfer at a comfortable sound level, a benefit for both the driver and the environment.
The modern design of the mower features standard integrated warning signs and road lights for maximum visibility and safety on the road.
Thanks to the specific set-up of the drum configuration, a very narrow swath is formed, which makes the use of double swath discs in many cases unnecessary. As a result, the mower is mounted closer to the tractor. Consequently, its already excellent weight distribution and centre of gravity is enhanced even further.
The PENDELFLEX oscillating headstock enables ground contour following in the lateral and longitudinal directions for superior ground adaption in hilly conditions. Moreover, the PENDELFLEX headstock ensures reduced wear, a lower power requirement and a preserved grass stubble.
The fixed headstock is a simple and economical solution for slightly hilly grounds. The flexible top link FLEXTOP (A) or telescopic top link FRONTFLEX (B) are optionally available.
