If you want to mow wide working widths of up to 8.84 m, then the PZ 8831 is the right drum mower combination for you. Farms with tractors as from 85 kW (116 hp) can now achieve maximum mowing widths, and therefore the highest work rates.

With the legendary drum design of more than 25,000 front and rear mounted mowers sold worldwide; these mower units have proven themselves in real, tough operating conditions. One special feature is its arrangement of mower drums: large outer drums and small inner drums produce a swath form to match the intake and follow the contours of the land perfectly. The freely rotating saucers make this mower very easy to tow.

The PZ 8831 is fitted as standard with LIFT-CONTROL. This hydro-pneumatic suspension system continually ensures a uniform ground pressure, lower pulling power requirement and non-stop mowing.

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 uneven sized diameter knife plates create a clean swath formation.

Safety and comfort when you need it

On encountering any obstacles, the material of the side cover bends, without breaking or damaging the mower.

FLEXPROTECT side covers

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.

LIFT-CONTROL

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.

The clear benefits of the KUHN LIFT-CONTROL are: Constant ground pressure
Excellent terrain following
Non-stop safety breakaway
Less crop contamination
Minimal damage to the turf

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.

LIFT-CONTROL is a suspension system with a nitrogen accumulator replacing the traditional spring. The system is making use of the kinetic forces that act on the mower unit.

Easy access to the drums

The front cover can be folded away, allowing easy access to the blades. This is perfect for daily inspections and mower maintenance.

The foldable front and side protective covers can be lifted upwards, convenient for daily inspection and blade exchange.

Detachment in folded-up position

The PZ 8831 mower can be detached and stored in folded-up position on the integrated supports. This saves considerable space in your shed or yard when storing the mower.

Quick and easy maneuverability

The PZ 8831 mower combination ensures an excellent weight transfer for the best maneuverability on sloping terrain.

Compact design for best weight transfer

The PZ 8831 has a weight of 2000 kg. With one front mounted mower and two mowers attached to the rear of the tractor, this mower combination ensures an excellent weight transfer for the best maneuverability on sloping terrain.

Adjustable working width and overlap

The working width of the mower can be adjusted to three widths: 8.30 m, 8.54 m and 8.84 m. This enables you to work with front mowers of different working widths and allows you to choose the right overlap when working on slopes.

The working width of the mower can be adjusted in three levels.

Reverse drive combination

With minor adjustments and an attachment kit for the front mower, it is possible to use the triple mower in a reverse drive combination.
