The PZ 270 and 300 models have a proven and tested drum design with over 25,000 units sold worldwide. Large outer drums and small inner drums offer benefits such as perfect ground contour following, clean swath formation and large throughput.

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 cutting height can be adjusted by adding or removing the optional spacers. This can be easily reached and infinitely adjusted.
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.
On hitting an obstacle, the mower unit pivots backwards, thus absorbing the impact. Reversing the tractor re-engages the safety system, and the mower unit is set back into the work position.
The front cover can be folded away, allowing easy access to the blades. This is perfect for daily inspections and mower maintenance.
The adjustable 3-point linkage enables you to shift the machine to the left or right. When using front and rear mower units in combination, this ensures that overlap is always at its optimum even when cutting round corners.
Without leaving the tractor seat, the PZ mower units can easily be put into the transport position behind the tractor. This function can be upgraded with a hydraulic cylinder. Furthermore, an optional hydraulic folding cylinder is available for improved weight distribution during transport.
The optional headland cylinder improves operator comfort across the larger widthed machine and gives the PZ 270 and the PZ 300 sufficient ground clearance when turning on the headlands
