Round drums do not transport well, that is why KUHN uses drums with two flat sides for optimal crop transport without the risk of blockages. Movement of the crop has an impact on the mowing quality. It is for this reason that KUHN has chosen to use screw-on transport strips.
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.
Using the special tool, you can push the knife holder down and simply replace the knifes. It is a quick and secure system.
The proven design with its uneven sized diameter knife plates has great benefits for the front mower: a clean swath formation, less crop contamination, perfect ground following and high throughput with a low PTO power requirement.
The arrangement of the drums has the added advantage that it is fuel-saving. Swath discs are available as an option.
Damage to the side covers is now a thing of the past. The KUHN FLEXPROTECT flexible side covers add a new dimension to these mowers 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.
Improve the quality of your forage and reduce downtime by using the exclusive LIFT-CONTROL suspension system. LIFT-CONTROL is much more than just a suspension system with a nitrogen accumulator replacing the traditional spring. It is an active and dynamic hydro-pneumatic suspension system making use of the kinetic forces that act on the mower unit.
It is when mowing on slopes that the LIFT-CONTROL system shows all its advantages and is reflected in a distinct reduction of fuel consumption and higher working rate.
Because time is money, adjusting the weight-reducing pressure takes just a few seconds! Through the accumulators, the ground pressure can be adjusted with great precision to adapt to the harvesting conditions, easily from the tractor seat. Therefore, on wet land minimal pressure on the ground prevents crop contamination. Lateral force, wear on the drums and tensile strength will be significantly reduced. As the force on the mower unit increases, the LIFT-CONTROL system automatically raise the unit. The greater the force, the lighter the mower unit gets.
The front cover can be folded away, allowing easy access to the blades. This is perfect for daily inspections and mower maintenance.
The PZ 320 mower articulates for excellent ground contour following on uneven terrain at all times. This makes the mower suitable for mowing on slopes and banks up to 30°.
For stable transport the machine has a folding transport position of 120°, the weight of the machine is placed more evenly between the rear wheels. This increases the safety and comfort in transport significantly and the tractor lights are always visible. A renewed geometry between the frame enables a low transport height of 3.6 m, with a ground clearance of 40 cm.
