To new shores –
the era of Bernhard Walterscheid-Müller
1952–1978
Bartering and improvisation end with the currency reform and the introduction of the Deutsche-Mark on 21 June 1948, and economic life is quickly revived. Walterscheid also once again increases production rather than just keeping afloat with repairs and small orders. Things are looking up: major customers, such as machine manufacturer Klöckner-Humboldt-Deutz (KHD) regularly procure their axle shafts from Walterscheid.
Bernhard Müller now wants to expand production and needs space for a larger factory. He finds a property that meets his requirements in his home town of Lohmar. Situated south-west of the town centre, it provides good access to the main transport route and to the A3 Cologne-Wiesbaden. It also offers a connection to the (now no longer existent) railway line. In January 1949, Walterscheid leases the 15,000-square-metre area and applies for the construction of “an extensive industrial hall”. The municipality of Lohmar welcomes the plans, which it believes will “effectively support economic activities in the municipality”.
Müller also expanded the company’s product range so as not to be dependent on a single product. Besides axle shafts, beginning in 1950 the company also manufactures starter ring gears – the so-called AZ range. When Jean Walterscheid retires for health reasons, Bernhard Müller takes on more responsibility and makes his mark at the top of the company. The employees are impressed at “how energetically, diligently and tirelessly this young man tackled his set tasks”. In particular, he has “an unerring ability to identify future opportunities”. The childless Jean Walterscheid decides to adopt his authorised representative and Managing Director and makes him the heir to the company. On 1 August 1952 he invites the entire workforce and their families, almost 200 people, to the factory at the mill stream. A long-term employee plays the violin and there is an entertainment programme before Jean Walterscheid delivers a speech. “We instinctively felt that this was an act that guaranteed the security of our jobs and the future of the company”, reports a participant. Walterscheid appoints Bernhard Müller as a joint owner; the Managing Director now bears the name Bernhard Walterscheid-Müller.

Polyphonic: the factory choir records numerous vinyl records in the 1980s.
Even as a successful businessman, Jean Walterscheid remains a cheerful soul who enjoys celebrating birthdays and Saint’s days in the factory. “Why don’t you sing”, he prompts the guests. This leads to the idea of a factory choir. Walterscheid’s brother-in-law, Karl Buchholz, founds the choir, with Peter Neuhalfen as the first conductor. The choir holds its first performance on 24 May 1946, Jean Walterscheid’s 54th birthday. The factory choir is soon not just singing at company events but also holding public concerts. After the choir fell silent at the end of the 1960s, it is revived by HR manager Ulf Clodius in 1978, who is able to get long-term chorister Heinrich Herchenbach involved. Karl-Josef Kappes is appointed as the conductor and a board is created. The choir now also attends events with soprano Margaret Price and tenor John Lapierre, and even releases records in 1981 and 1985. A highlight is the anniversary concert at the Hennef “Meys Fabrik” in October 1996. In 2003, the choir disbands following the death of long-term conductor Karl-Josef Kappes, due to a shortage of new recruits.
Entry into agricultural engineering
In the early 1950s, agriculture benefits from high prices for its products and invests primarily in mechanisation. Walterscheid takes advantage of this development. In the autumn of 1952, engineer Kurt Schröter joins the company and forms a perfect duo with Bernhard Walterscheid-Müller. “A brilliant designer and a visionary business owner joined forces”, gush companions decades later. The two men take a close look at agriculture and note the increasing popularity of tractors and agricultural machinery. Together they develop the idea for Walterscheid to enter this market.
Agricultural machines need drive shafts, but the requirements of agricultural machinery manufacturers differ from those of other Walterscheid customers. In motor vehicles and many other machines, the drive shafts are permanently installed and are only slightly angled, while agricultural machines require compact joints with short fork legs. In agriculture, devices are often coupled and uncoupled and operated at large angles, especially when cornering and in narrow fields. Many agricultural machinery manufacturers produce their own drive shafts at the time; Walterscheid repairs quite a few and knows their weaknesses. There are a multitude of different types; repairs are difficult and spare parts are scarce. Dangerous accidents are often caused because drive shafts between the machine and the tractor do not have a guard and are freely accessible. There is also a lack of overload clutches, which prevent the overloading of the machine. Walterscheid is convinced that they can offer a better product. The company takes the step into agricultural engineering with a special drive shaft designed by Kurt Schröter.
Mechanisation of agriculture
Until well into the 20th century, agriculture is primarily reliant on the labour of humans and animals. The advent of the milking machine in the 1920s marks the start of the mechanisation of the industry. It soon also extends to field work: larger operations use motorised tractors, whose number increases to around 30,000 by 1939. The changes in West Germany after the Second World War are particularly severe: between 1950 and 1965 more than a million horses are replaced by 800,000 tractors. The agricultural industry becomes increasingly important as, in addition to a number of tractor manufacturers, producers of combine harvesters and tilling machines generate huge amounts of revenue. The transformation is impossible to ignore. Workers stream into the industry, but the number of people employed in agriculture halves to around 2 million by the mid-1960s. Their work is now largely performed by all kinds of machines.
In the meantime, agricultural machinery develops from pure tractor units to drive sources. For example, the US company McCormick launches a sheaf-binding harvester on the market, which binds the grain stalks into bundles (sheaves). The machine is driven by the tractor via a PTO shaft. Soon afterwards, this new type of drive is being used by other agricultural machinery manufacturers. The power take-off even leads to the development of new machines, such as high-pressure balers for hay and straw.
Tractors, such as the popular Lanz Bulli, make work easier in the 1950s – during the hay harvest and many other activities.
Kurt Schröter takes Walterscheid a giant step forward with his designs for agricultural engineering.
Jean Walterscheid (left) and Bernhard Walterscheid-Müller have plenty of reasons to celebrate in the 1950s, and so they did.
Walterscheid finds a solution to the accident risk of drive shafts with its guard.
When Walterscheid presents its new drive shaft series at the German Agricultural Society (DLG) trade fair in Cologne in 1953, it is a minor sensation. It is the first appearance of a drive technology specialist in agriculture. The presentation of drive shafts for agricultural machinery is also a gamble. While Walterscheid does not have any competitors at the time because no specialist manufacturers exist, there are also no customers. The aim now is to convince agricultural machinery manufacturers to give up their in-house production and purchase these from suppliers. The key is the high quality of the Walterscheid drive shaft. It is suitable for a wide range of agricultural machines, such as harvesters, sprayers and manure spreaders.
Walterscheid drive shafts have a number of benefits – above all, the world’s first drive shaft guard. In addition, the drive shafts have integrated overload clutches, which prevent damage to the tractor and machine if the agricultural machinery is blocked or overloaded. Walterscheid offers customised solutions for different machines. For instance, in high-pressure presses or rotary mowers, the large rotating masses run-on after they are switched off, so that the drive shaft also rotates and is able to lock. Overrunning clutches, which transmit the torque in only one direction, prevent this dangerous situation.
The quick-disconnect pin, which enables convenient coupling, is another innovation. The telescopic profile tubes are also new. These allow the distances between tractors and machines to be increased and adjusted. The profiling also ensures that the two driveshaft halves can only be pushed together with a 180-degree offset so that the correct fork position is always ensured. This makes incorrect assembly impossible. In use, the profile impresses with its low vibrations and low displacement forces, as well as low wear thanks to its large contact surfaces.
Walterscheid’s drive shafts prove their worth – for example, here in an Amazone seeder – and particularly impress with their safety.
The acquisition of axle shaft manufacturer Vernimb in 1953 strengthens Walterscheid with an additional production site.
In 1953, Walterscheid acquires axle shaft manufacturer Max Vernimb from Kiel and enters into the export market, as Vernimb’s success is primarily international. The year after, the company becomes a limited partnership. Jean Walterscheid and Bernhard Walterscheid-Müller are joined by Kurt Schröter and two other limited partners. Walterscheid starts mass-producing agricultural drive shafts (LGW) and grows rapidly. The Heinrich Lanz AG agricultural machinery factory in Zweibrücken, which is subsequently taken over by John Deere, is a customer from the very beginning. In 1954 the first mass-produced Walterscheid drive shaft is in operation in the Lanz potato harvester. The sprayers in the Standard range manufactured by Holder und Stalldungstreuer in 1955 also use Walterscheid drive shafts.
The LGW programme runs so well that there is no longer enough space on the first floor of the old “Hansenmühle”. Even a 2,000-square-metre hall erected at the Siegburg mill stream in 1954 only provides short-term relief. But Bernhard Walterscheid-Müller has prepared for this and has now purchased the initially leased property in Lohmar. An assembly hall covering around 4,000 square metres is constructed.
In addition, Walterscheid establishes national customer service centres to advise farmers, while representative offices are also opened abroad. These local contact points allow Walterscheid to supply farmers with spare parts and also learn a great deal about their practical requirements. This gives the company a good insight into developments in agriculture, and it aligns its production accordingly. In 1955, Walterscheid employs 400 staff and annual sales exceed a million marks for the very first time.
Walterscheid builds its first hall in Lohmar at the end of the 1950s – this marks the start of the relocation from Siegburg to Lohmar.
Dr Bernard Krone, owner of the Krone Group and long-term Walterscheid business partner
Krone: “A strategic partner on which we can rely one hundred percent”
Today, Maschinenfabrik Bernard Krone, from Spelle, founded in 1906, is a leading global manufacturer of agricultural machinery for grassland technology. Bernard Krone, from the third generation of the family-owned company, first heard of Walterscheid while completing his Mechanical Engineering degree. He remembers how “references to occupational health and safety constantly made mention of the safety aspect of the Walterscheid drive shaft, the first fully-protected drive shaft. There is no doubt that this has prevented numerous serious accidents over the decades”. The companies first work together on the Optimat manure spreader, which Krone launches on the market in 1957. The universal loader for loading and unloading grass, straw, hay and silage, launched in 1963 also operates using Walterscheid drive shafts. Krone and Walterscheid develop components for machines in a cooperation spanning decades. Even though Bernard Krone “has to swallow hard on one or two occasions due to the prices”, he was convinced by the “outstanding” quality. This was also true for the spare parts supply and the service. His conclusion after six decades of cooperation: “Walterscheid is an important strategic partner and systems supplier on which we can rely one hundred percent”.

Walterscheid’s wide-angle joint is a practical solution for cornering and narrow areas.
What works well, and what can be improved? To implement and test suggestions from agriculture, in 1955 Walterscheid sets up testing department, known as “the Test” for short. It develops ideas and concepts that are discussed and optimised together with important customers. The regular exchange of ideas improves quality and establishes trust. After just a few years, Walterscheid is able to make significant improvements, such as for one general problem with drive shafts: they transmit rotary motion unevenly when cornering. This leads to strong vibrations and high wear, which causes damage to the machines and drive shaft. As a result, Kurt Schröter designs a joint for large angles. The externally controlled double joint permits a power transmission of up to 75 percent. It is used in drive axle trailers and drawn combine harvesters, among others, which are still very popular in the 1950s.
The need for overload clutches increase in this period. Inside soundproof tractor cabins, drivers could barely even hear a machine malfunction. Walterscheid therefore develops clutches that automatically switch off and then back on when the speed is reduced or after stopping. These type K60 automatic clutches are widely used, including in field harvesters.
Expansion of service and internationalisation
When Walterscheid publishes its first practical technical manual with comprehensive product and application descriptions in the spring of 1956, the catalogue contains 106 drive shafts. Beginning in 1957, Walterscheid produces this wide range in its new factory in Lohmar. The company also continues working on innovations, always in cooperation with machine manufacturers and users. As the performance data provided by agricultural machinery manufacturers is often imprecise, in 1958 Walterscheid establishes a torque measurement service. “The Test” constantly deals with the problems that arise when drive shafts are not optimally adapted to machines and tractors. Drive shafts must work smoothly and transmit power. It is therefore important that overload clutches are aligned to the tractor/trailer combination. Walterscheid starts to determine the power requirement of machines directly in the field together with customers. This benefits both sides: test times are shortened and the risk of malfunctions and complaints is reduced.
Walterscheid’s success arouses interest, and two European competitors are interested in purchasing the company: the already affiliated Glaenzer Spicer (France) and Hardy Spicer from Great Britain. But Bernhard Walterscheid-Müller has other plans, and convinces the Spicer Group to enter into a cooperation. In 1958, they come together to establish two national sales companies for drive shafts: Hardy Spicer Walterscheid Ltd. in Birmingham and Glaenzer Walterscheid in Poissy (near Paris). Walterscheid itself is increasingly relocating to Lohmar. In September 1959, the administration department moves into a new, modern building, while the axle shaft production department moves into a second machine hall (hall 2). Lohmar is now the official company headquarters.
New business areas
In 1958, Walterscheid turns its attention to a new business area and buys Stuttgart-based Arnold Mohr, which manufactures hydraulic tube fittings. These are used in construction and forestry machinery, in shipbuilding and in the food industry. Tube fittings are also required for agricultural machinery, such as combine harvesters and forage harvesters. The fitting consists of a body, a union nut and a flow ring. The tube is fastened in the fitting by the ring and sealed.
Bernhard Walterscheid-Müller develops the product even further, performing pressure tests and declaring the connection system to be “disappointingly poor”. His solution: he replaces the flow ring with a double wedge ring and files a patent application for the new design, called the Walterscheid tube fitting. This is available beginning in 1960; the new sales manager Leo Schwertje and his team present it at the industrial fair in Hanover in April. The key customers primarily include construction machine manufacturers and shipyards, such as AG Weser and Bremer Vulkan. Annual sales of the new product quickly rise to a million marks. But, given the total sales of 50 million marks in 1961, this is only a small business area.
Walterscheid and its almost 1,000 employees are primarily focussed on agricultural engineering. Schröter uses his contacts at the Agricultural Engineering department of the Technical University of Cologne to acquire well-qualified personnel. At the International Motor Show (IAA) in 1963, his team holds discussions with tractor and transmission manufacturers and introduces ideas for a dual clutch. The aim is to combine the gearbox and power take-off with a single clutch in each case. The dual clutch allows Walterscheid to attract additional tractor manufacturers, which had previously already purchased axle shafts, as customers. This includes Steyr, Schlüter and Kramer Lamborghini. In 1962 the Max-Eyth-Gesellschaft Agrartechnik awards Kurt Schröter its highly esteemed commemorative medal for the design of these clutches and the drive shafts, among others.
A new tube fitting design opens up an additional business area for Walterscheid.
Strong together: Uni-Cardan
After the company’s successful entry into agricultural engineering, Bernhard Walterscheid-Müller looks for new sales markets and establishes production outside Germany. In 1963 Walterscheid and its partner company Hardy Spicer, which becomes part of the English Birfield Group shortly thereafter, establish a plant in Bruneck, Italy. Birfield-Trasmissioni, the plant in South Tirol, begins operation in an economically underdeveloped region and soon develops very positively.
These good experiences with the Spicer Group induce Walterscheid-Müller to take an unusual step: he proposes the merger of six drive shaft manufacturers from four countries. Besides Walterscheid, this includes Gelenkwellenbau from Essen and Löhr as well as Bromkamp from Offenbach and Schmiede- und Presswerk, founded in Trier. Other partners are Birfield-Trasmissioni in Italy, Glaenzer Spicer in France and the Birfield Group. In 1964, they jointly found the Uni-Cardan public limited company.
The merger is financially strong and enables the exchange of knowhow, as each manufacturer has its own areas of focus. Sales and service are easier to organise together. Bernhard Walterscheid-Müller remains the Managing Director of Walterscheid and is appointed the CEO of Uni-Cardan, which establishes its headquarters on the Walterscheid premises in Lohmar. The name Uni-Cardan is coined by Kurt Schröter after Gerolamo Cardano, the inventor of the cardan shaft. Walterscheid shares, including those of Kurt Schröter, the Walterscheid family and Bernhard Walterscheid-Müller, are converted to Uni-Cardan shares. This makes Walterscheid a subsidiary of Uni-Cardan and, for the very first time, it has joint owners from outside the company. The most important of these is the Birfield Group, which holds just under 40 percent of Uni-Cardan.
A European merger: Uni-Cardan AG unites plants from several countries.
Construction work in an alpine setting: Birfield-Trasmissioni, the plant owned by Walterscheid and its partner company Birfield, is constructed in Bruneck, South Tirol, in 1963.
In the 1960s, workers from Portugal are welcomed with open arms and stay with their families, often across generations.
By 1970, the Lohmar plant has grown impressively, and the administration building now extends across five storeys. The hangar that contained the training workshop is located on the front right, with the combined heat and power station with chimney behind it.
Eagerly awaited by journalists and farmers: at the DLG in 1974, Walterscheid presents the innovative Walterscheid coupling system (WKS) in its practical application.
Product development continues. The tube fittings division of Walterscheid designs a DIN-compliant fitting that appeals to a larger customer base. As the base elements are exchangeable, the new fitting is also compatible with the existing system meaning that no conversion is required by customers. Walterscheid’s introduction of these fittings with DIN-compliant cutting and wedge rings beginning in 1973 also leads to the acquisition of new customers in agricultural engineering. In addition to drive shafts and overload clutches, Grimme, Krone and KHD now also purchase tube fittings from Walterscheid.
In its tireless work on solutions for agricultural engineering, Walterscheid is particularly committed to safety, because despite improved drive shaft protection, accidents continue to occur when coupling and uncoupling machines. A more convenient and safe system would be one that allows coupling to take place from the tractor cab. This is first made possible by the Walterscheid coupling system (WKS), which is presented at the DLG in Frankfurt in 1974. The key element of the WKS is the hook coupling as a tractor attachment. Following the market launch of the WKS in 1974, the next year Walterscheid presents an improved three-point coupling system under the brand name Walterscheid two-stage coupler.
These days, this innovation is an indispensable part of agricultural engineering, but it was initially met with scepticism. Tractor manufacturers are hesitant to install the new coupling system due to the cost. But Walterscheid is tenacious and goes directly to farmers to convince them of the benefits of the system. Technicians travel to villages and weld the hook – the key element of the new system – onto tractors on location. It is a resounding success: the benefits in practical application are obvious. Farmers now exert pressure on manufacturers to integrate the new system into their machines as a standard solution. This once again made crystal clear that benefit for the user is the deciding factor in the success of Walterscheid products.
Walterscheid remains particularly successful with its drive shafts and, in 1974, sets a production record: 1.1 million drive shafts in one year! That same year, the company is also able to acquire an industry giant, Claas, as a customer in Germany. Claas has already been manufacturing some of its Markant presses in Algeria using Walterscheid drive shafts for a number of years. The agricultural machinery manufacturer now decides to purchase the drive shafts for its Markant presses in Harsewinkel as well.
Walterscheid decides that the time is right to look for business outside Europe and, in 1976, establishes a US subsidiary in Burr Ridge, Illinois (near Chicago).
Walterscheid places great importance on cooperation – at the workplace, like here in the Lohmar forge, and after work, such as at a joint bowling evening.
Cathrina Claas-Mühlhäuser,
Chairwoman of the Supervisory Board of the Claas Group, a long-standing partner of Walterscheid
Claas: “The cooperation has always worked exceptionally well”
Claas, a family-owned company founded in 1913, with its headquarters in Harsewinkel, East Westphalia, is a market and technology leader in harvesting technology. Today, Cathrina Claas-Mühlhäuser, from the third generation, is the Chairwoman of the Supervisory Board of the Claas Group. She can see similarities with Walterscheid. Both originated as small regional operations and grew to become global players, and both value reliability and quality.
Yet their decades of positive cooperation start quite late as as, for a long period, Claas places importance on its independence and relies on its own technical expertise. This changes in the 1960s, as the company grows significantly and soon generates more than half of Germany’s total sales of combine harvesters. “Once you start producing large quantities, at some point complete independence is just no longer feasible”. Claas has installed Walterscheid drive shafts in combine harvesters and other harvesters since the early 1970s.
These days, their share of Walterscheid drive shafts is at around 50 percent. Cathrina Claas-Mühlhäuser emphasizes the importance of the purchase decision: “Drive components account for 15 to 20 percent of the overall costs”. This experience reflects positively on Walterscheid: “We never had any problems; the cooperation has always worked exceptionally well”.
Walterscheid shafts were installed in the Claas Jaguar F6 beginning in the 1970s.
