Over 50 years of expertise
Created in 1828 by Joseph Kuhn as a modest village forge, KUHN was an early specialist in the production of scales and weighing apparatus. In 1949 a decisive step was taken: by converting to mechanical traction in that year, KUHN became one of France's leading agricultural machinery manufacturers.
It was the start of a terrific period of development! With growing mechanisation and modernisation of the countryside, KUHN multiplied its new machines.
Innovation, quality: these were the company's keywords, leading it to a position as a reference trademark in agricultural machinery. Discover here the history of over 50 years of expertise.
In the mid-1960s, the first KUHN Gyrotedders with two or four rotors enter the market.

With the GMD 4, KUHN presents the first disc mowers. The new technology immediately proves itself as it performs well and cuts smoothly in difficult conditions with lodged forage. The daily process of sharpening the knives of finger bar mowers becomes a thing of the past; and the great advantage of the GMD 4´s oval discs? They actively assist crop flow to the back of the swath, regardless of whether working on flat land or hillsides.

With the GA 230 and GA 280, KUHN introduces the first Gyrorakes on the market and thereby starting a new era in raking technology.

The mid-1970s mark the start of combined mowing and conditioning for KUHN and machines which perfectly complement the existing conventional mowers are offered. On the new FC 44, steel finger rotors condition the cut crop and send it through an adjustable comb. The swath boards then ensure an airy and regular swath is created. This new technology is especially beneficial for the quality of the forage as it accelerates the drying process.
The start of combined mowing and conditioning
Introduction of tangential tine arm control on the GA 402: the new position of the tine arms considerably enhance the delivery and shape of the windrow.

With the FC 300, KUHN launches its first trailed mower-conditioner.

KUHN files a patent for the double-curved tine arms on Gyrorakes. They provide a much improved output and increased working speeds. Combined with the steep cam track, they make for regular and optimally delivered windrows.

Wide-angle rotor drives via universal joints on tedders require daily greasing. KUHN introduces the DIGIDRIVE finger coupling on their tedders and thereby eliminates this annoying and time-consuming work. The patent allows a new, more compact machine and prevents damage to the drive train when folded.

KUHN presents the first trailed disc mower-conditioners with lengthwise transport.

The KUHN LIFT-CONTROL system considerably improves the ground adaptation and suspension of the mowing units. The unique kinematics, with integrated Non-Stop safety, ensures a constant cutter-bar ground pressure and therefore optimum protection of the sward. LIFT-CONTROL is fitted on both GMD mowers and FC mower-conditioners.

The two-stage reduction MASTER DRIVE gearbox with spur-gear drive of the rotor gearwheels is launched. In the first step, it is fitted on wide-width Gyrorakes.

To satisfy the growing demand for high-performance rakes, KUHN presents the MERGE-MAXX 900 belt merger, a new and unique raking concept. Its impressive flexibility and multi-purpose characteristics quickly stimulate great interest and convince customers: firstly in North America, but soon afterwards also in Europe!

Increasing working speeds and greater volume of forage leads to increased demands as to the robustness of mowers. The KUHN answer is the new OPTIDISC cutter bar with differing distances between the discs. This high-performance cutter bar – designed for wide working widths – increases the crop flow and spares the farmer the need to change the cutter bar oil once a year.

The new SW 4004, which is able to wrap both round and square bales, becomes one of the first ISOBUS-compatible wrappers on the market.

The LSB 1290 iD high-density baler with the new TWINPACT-two plunger system is presented. This intelligent technology compresses the bale in two steps, reaching up to 25 % additional density compared to a standard LSB. This is achieved without massive peak loads and therefore the same power requirement as for conventional LSB balers is maintained.
KUHN launches two key innovations on the new Gyrorake GA 8030 with side delivery. STABIDRIVE increases safety both when turning and when working on slopes, whilst the new STABILIFT rotor articulation stabilizes the rotor as soon as it is lifted. STABILIFT also allows smooth rotor lowering on the ground: rear part first followed by the front part. The plant cover is perfectly protected and forage contamination by soil is prevented.

To increase the performance of their wrappers KUHN introduces e-Twin, a new wrapping technology which saves 50 % of time spent wrapping. Due to its unique combined pre-stretcher design, higher turntable speeds are possible. In addition, the film is incredibly resistant to tearing and so making the wrapping very secure. As the film is better pre-stretched and positioned by the double pre-stretchers, film costs can be reduced!
