As reliable and economical as the big mowers

Suitable for small and medium-sized farms, these PZ mowers build on a legacy that goes back over 50 years to the introduction of the world’s first drum mowers. They have been refined through the years without changing what made them great.

With the three models of drum mowers PZ 170, PZ 190 and PZ 220, KUHN provides high-quality technology at working widths of up to 2.10 m. These KUHN drum mowers are suitable for small and medium-sized farms. Their long-life and easy and safe operation are the key attributes of these machines.

The PZ 220 can be retrofitted with a conditioner which can be removed without any tools thanks to a carefully designed centre section and practical quick-locking mechanisms.

Cleverly designed components for optimal performance

Flat sided drums

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.

Height adjustment

The cutting height can be adjusted by adding or removing the optional spacers. This can be easily reached and infinitely adjusted.

Freely rotating saucers

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 saucers of the drum mower can rotate freely

Quick knife exchange

Using the special tool, you can push the knife holder down and simply replace the knifes. It is a quick and secure system.

Using a hook shaped tool, you can simply replace the knifes.

Perfect swath formation

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.

The big size knife plates create a clean swath formation.

Safety and comfort when you need it

Compensation springs

Compensation springs are fitted as standard to transfer the weight from the mower unit to the tractor in order to keep ground pressure as low as possible.

Safety break back system

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.

Quick and easy maneuverability

Easy hitching

The PZ 170, 190 and 220 can be hitched easily to every tractor with Cat. 1 or 2 linkage pins. KUHN can provide a special adapter to fit wider tractors.

Working-transport position

Without leaving the tractor seat, the PZ mower units can easily be folded into the transport position behind the tractor. An optional hydraulic folding cylinder is available for improved weight distribution during transport.
