Over the last 50 years KUHN Group has contributed to the developments and innovations of disc mowers and mower conditioners, and continues to do so :
We offer mowers that have been designed, developed and produced entirely by KUHN...
...down to the finest details, to guarantee that the machine you buy is of the highest quality.
Producing good quality forage for a herd whilst reducing production costs is a key challenge for today’s farmers.
KUHN's product development teams are constantly working to find solutions that retain forage quality, using cutting edge technology, engineering and quality materials. 'Reducing forage contamination from 4% to 2% can save you £78/ha/year*

Oval discs facilitate forage flow to the rear, preventing overlapping which can lead to forage loss.
The OPTIDISC cutter bar optimises forage flow, especially with large volumes and at high speeds, due to wider spaced converging discs. This also contributes to improving mowing quality in difficult conditions. Reduced spacing between diverging discs increases overlap between the blades resulting in a cleaner cut.
The different suspension systems and clever kinetics of the disc mowers provide perfect ground contour following thanks to:
Mowers with LIFT-CONTROL hydro pneumatic suspension benefit from constant, easily adjustable ground pressure, keeping your forage clean from impurities.
The wide setting range of the rotor with fingers (multiple possibilities with rotation speed and comb position) makes it easier to adapt conditioning intensity to the type of forage, crop maturity and weather conditions.
For more delicate crops use the conditioning roller. It is pressure adjustable to preserve the leaves of leguminous plants.
Forage delivery can be adapted to suit humidity levels and weather conditions. Wide spreading aids faster drying and a narrow swath delivery prevents the wheels of the tractor flattening the forage.
Components such as discs and skids are essential for a high quality cut and therefore they are integrally manufactured at KUHN. Once shaped they undergo specific treatments to hardent hem to abrasion resistant standards, as well as prodcing the optimum anti-vibration shape. Knife features (quality of steel and treatments, shape, resistance to deformation due to violent impacts and wear) are also one of our priorities, for both your safety and profitability.
Once produced, individual parts undergo many checks before being sent to the assembly line. At the end of the line, each cutter bar is put through a functional check (operating temperature, bearing temperature, power requirement,…). At the end of the assembly line, powertrains and hydraulic and electric circuits are controlled on the machine and large sub-sections.
A fully assembled machine is pulled out of each series produced, to undergo intensive driving tests on the road, on pathways and in the field before being taken apart for appraisal.
The GIRODINE headstock that trailed mower conditioners and mowers are equipped with is the perfect illustration of this.
It enables you to work at high speeds in total safety. Even in the tightest of angles and at full speed, the main transmission is always aligned with the tractor and protected.
GMD mowers and FC mower conditioners with LIFT-CONTROL come with an active “NON STOP” safety system.
Should the machine meet an obstacle, the mower unit pivots upwards towards the rear, to avoid it. It then returns to the working position as soon as the obstacle has been cleared.
The FAST-FIT system is available on most KUHN mowers and mower conditioners. Changing knives safely takes no time at all!
The cutter bar is a genuine precision mechanism that is subjected to difficult conditions: intensive and long operations, high-powered tractors, highly uneven ground, mowing components very close to the ground and likely to meet obstacles... Cutter bars, disc bearings and gearwheels are essential parts that undergo high precision machining, various phases of heat treatment, followed by intense levels of quality control. For example, this has enabled us to offer the widest cutter bar on the current market (5.20m) that does not need oil changes.
In addition to the LIFT-CONTROL suspension system, other systems protect the vital components of the mower or mower conditioner to extend the life of your machine.
In case of a sharp impact between a disc and an obstacle, the disc shaft will shear just above the bearing, thanks to an integrated shear groove.
The PROTECTADRIVE system protects the gearwheels. The savings are huge: in less than 15 minutes the machine can be back up and running at a low repair cost.
Latest generation disc mowers are equipped with shock absorbers between the cutter bar and the chassis. They reduce vibrations effectively, especially at higher speeds and contribute to a longer machine life.
KUHN’s newest disc mowers and mower conditioners have FLEXPROTECT polythene side guards that bend without breaking and without damaging the machine if hit by an obstacle.
Having the foundry enables us to provide the farmer with innovative technical components. The chassis is linked to the cutter bar with a flat angle bracket in SG quality cast iron (spheroidal graphite, similar to steel) and equipped with silent-blocs to reduce vibrations caused by fast mowing on hard ground. It also reduces wear and constraints in the cutter bar support zone. A KUHN patent.
Mowing conditions vary throughout the world, therefore we need to be able to offer advanced technical solutions with components such as cutter bar bearings. Unlike many bearing manufacturers we are able to offer key elements including lubrication quality, better sealing, abrasion resistance, reduced clearance and high rotation speed.
The global population is ever increasing. By 2050, the worldwide population will have increased by 2 billion people, therefore agricultural production will have to double to keep up with the world demand.
At the same time, farms will only get bigger and be using more advanced technology. Advances in management are already starting to revolutionise farming businesses.
The key to meeting the challenges in mowing and other areas of agricultural production is developing technologies. Today, around 50 people work on electrical developments.
KUHN group continues to invest in research and development to meet your needs and requirements in terms of quality, performance, profitability, precision and connectivity.
To make your investment great and retain KUHN’s status as the world’s best-selling disc mower manufacturer!
In 1949, KUHN decided to move to mechanical traction and began to manufacture tailored machines. They soon became one of the first agricultural machinery manufacturers in France to modernise agricultural practices. The first mechanical traction mowers were side mounted, with finger bars.
Innovation and quality swere the main priorities whilst gaining recognition within the agricultural machinery sector.
More than 26,000 machines were produced each year in KUHN Saverne, France including:
- 12,000 side finger mowers.
- 9,500 tedders and rakes.
Benefit: this machine allowed increased working speed, improved operator comfort and maintenance..
The GMD 4 disc mower rapidly became the world leader.
Benefit: This enhanced forage quality, created more uniform swaths and improved the drying process.
Benefit: The FC 300 provided great maneuverability along with a high level of operator comfort.
Benefit: This machine also heled to support the demands of a high work output with a 5 metre working width.
- The KUHN LIFT-CONTROL system, found on both GMD mowers and FC mower conditioners was developed in 1994.
