MAN Engines
As a manufacturer and developer of diesel engines, MAN has been closely associated with agricultural engineering since the early 1920s. The innovative engines were initially installed in the company’s own machines – from motorised ploughs to the company’s tractors – but were later increasingly sold to other manufacturers.
Today, MAN engines can be found in agricultural machinery from a wide range of manufacturers and are in particular used in areas with high demands on performance and efficiency. Market and technology leaders in the agricultural industry rely on MAN for top engines in combination with their machines.
The MAN D4276 with a displacement of 16.2 l is now also in service in the LEXION 8800 and 8800 TT combine harvesters. With 515 kW / 700 hp, this means more engine power and an optimized torque map for the LEXION 8800/8800 TT and the same modern MAN engine as in the most powerful LEXION 8900 variant with 581 kW /790 hp (see picture).
MAN Engines is now the engine supplier for Albach Maschinenbau, which will be fitting the MAN D4276 six-cylinder inline engine in its Diamant 2000 self-propelled wood chipper. For the update to the Diamant 2000, which has been in production since 2014, Albach is moving to a new engine supplier in MAN Engines, and has chosen to power the vehicle and the integrated chipper with the state of the art 790 HP (581 kW) MAN D4276 LE122.
The Fendt 1100 Vario MT series expands its range with four models – from 511 HP to 673 HP (according to ECE R 120) – and relies on the MAN D3876 engine series with 15.3 litres displacement or the MAN D4276 with 16.2 litres displacement for a maximum power of 673 HP in the Fendt 1167 Vario MT. All engines meet the European emissions standard Stage V by means of exhaust gas recirculation, a diesel oxidation catalyst (DOC), a diesel particulate filter (DPF) and the well-known Selective Catalytic Reduction (SCR) technology.
In 2019, the top model of the new generation is the first forage harvester to feature the new V-MAX 42 chopping drum. With the 952 HP (680 kW) MAN D2862 engine and CLAAS intelligent control, the JAGUAR 990 achieves impressively low fuel consumption. In the Jaguar 970, the new D4276 with an output of 581 kW (790 HP) replaces the V8 engine.
In 2019, the new powerful IDEAL 10 adds another top model to the IDEAL series of large combine harvesters from the AGCO Group. With the MAN D4276 engine, it achieves a maximum output of 581 kW (790 HP) and complies with the European emissions standard Stage V.
CLAAS introduces a new generation of LEXION combine harvesters. The 6900, 7600 and 7700 models are powered by an MAN D2676 engine. There is also the newly developed straw walker with an additional separator drum for uniform crop flow and gentle processing of grain and straw.
Thanks to the 900 series, Fendt 2019 covers the power spectrum between the 800 Vario and the 1000 Vario. All five models are equipped with a 6-cylinder engine (MAN D1556) newly developed by MAN and designed for Fendt. With the new 942 Vario, which was unveiled at the beginning of July 2019, the 900 series goes over 400 HP for the first time.
In 2019, CLAAS entered a new performance class with the LEXION 8900. The high-performance combine harvester is powered by a 790 HP (581 kW) 6-cylinder engine. The engine power of the D4276 is adapted to the operating conditions with DYNAMIC POWER, ensuring maximum fuel efficiency.
In 2017, AGCO receives the Silver Innovation Award at Agritechnica with its new IDEAL combine harvesters. The two combine harvesters IDEAL 8 (D2676) and IDEAL 9 (D3876) have been developed from scratch and achieve the highest throughputs with efficient fuel consumption using MAN 6-cylinder engines. The combine harvesters are marketed by the Fendt and Massey Ferguson brands.
With the 1000 Vario series, Fendt is entering new performance ranges. The world’s largest standard tractor is powered by the MAN 6-cylinder engine D2676. The most powerful of the four-model series achieves a maximum output of 517 HP (380 kW). In addition to high performance, the engines are also characterised by extremely low fuel consumption.
In view of growing transport tasks in agriculture and forestry, trucks are also playing an increasingly important role in the fields and forests. MAN offers special conversions for these applications for the TGM, TGS and TGX models for agricultural work, for wood chippers and for timber transport.
In 2011, Claas introduces a new generation of its powerful forage harvesters. The two top models, Jaguar 970 and 980, are equipped with MAN V8 and V12 engines. At Agritechnica 2011, the Jaguar receives the “Machine of the Year” award. The decisive factors here are, among others, the MAN engines and “Dynamic Power”, the needs-based power control with which the engine always operates at the optimum consumption level.
The high-performance BiG M 420 and BiG M 500 mower-conditioners have been equipped with MAN engines since 2011. The in-line 6-cylinder D20 with 420 HP (309 kW) was installed in the BiG M 420 and the D26 with 500 HP (368 kW) in the BiG M 500. Both engines use SCR technology, in which an aqueous urea solution is injected in the exhaust tract. The result: significantly lower pollutant emissions.
Currently the most powerful forage harvester and also one of the largest agricultural machines in the world, the BiG X 1100 from Krone impresses with its 1,078 HP. Its engine, the MAN D2862, has twelve cylinders with 24.24 litre displacement. The BiG X series models were equipped with MAN’s powerful and efficient 8- and 12-cylinder engines.
At Agritechnica 2007, the Fendt concept study TriSix causes a sensation. Weighing 19.3 tonnes, the large tractor has three axles and rides on six wheels. The agricultural giant is powered by an MAN in-line 6-cylinder engine (D26) with an output of 540 HP.
In 1996, Holmer Maschinenbau GmbH introduces the “Terra Dos” beet harvester. The self-propelled harvester is equipped with a 460 HP 6-cylinder MAN engine. For its successor Terra Dos T3, the power is increased to 520 HP. A 340 HP MAN engine is used to power the beet harvester, which was introduced in 2009.
Fendt met the increasing demand for tractors in the top performance classes in 1993 with the introduction of the Favorit 800 series and in 1996 with the launch of the Favorit 900 Vario series. The engine output of 165 to 260 HP (121 to 221 kW) is provided by an MAN 6-cylinder unit with turbocharging. Oil pan and crankcase are built so sturdily that they serve as load-bearing parts in the superstructure of the large tractor.
The Favorit 622 LS and 626 LS models, also called “coatis” because of their long bonnets, are giants of their time. With these models Fendt exceeds the 200 HP mark. Under the bonnets are MAN 6-cylinder engines producing 211 and 252 HP.
The Freising-based tractor manufacturer Schlüter is known worldwide for its tractors in the upper performance classes. From 1973 onwards, Schlüter tractors are also fitted with MAN 4-cylinder, 6-cylinder and, in one case, even 12-cylinder engines. These are mainly models from the Profi Trac, Super Trac and Euro Trac series.
MAN had already been cooperating with Rába in Hungary before World War II. Since 1973, Steiger articulated trucks have been reproduced there, but equipped with a reliable licensed MAN engine. This includes one of the most widely built articulated truck models, the Rába 250. This four-wheel drive tractor with 250 HP set new standards in the Eastern bloc at the time.
In 1964, the first ZT 300 is built at the IFA (Industrieverband Fahrzeugbau) in the GDR. It became the forefather of a long line of medium to heavy tractors designed for use on the large LPGs (agricultural production cooperatives). The diesel engine of this tractor legend is a 4-cylinder unit that uses MAN’s licensed M process.
Low consumption, smooth running and high performance are the hallmarks of the centre-ball or M engine developed by Siegfried Meurer of MAN in Nuremberg. Unlike the G-engine, the spherical combustion chamber is located in the centre of the piston. Because of the smooth combustion, the engine is also nicknamed the “whisper engine” and the “engine of silent power”. From 1954 onwards, all new MAN models were equipped with engines of this kind, such as the 4 S 2 large tractor introduced in 1957.
MAN is one of the pioneers in the introduction of the all-wheel drive. MAN recognised early on how significant four-wheel drive can be in agriculture – today, it is ubiquitous. As early as 1948, MAN introduces the Ackerdiesel AS 325 A, is practically unrivalled among standard tractors on the German tractor market at the time.
In 1937, MAN introduces the spherical combustion chamber and the flat-seat nozzle to the engine technology: the G process (G = globe). The eccentric hollow ball in the piston head reduces heat loss and improves fuel combustion. The first MAN tractor, the AS 250 with 50 HP from 1938, also has a G-engine.
From 1918 onwards, following Rudolf Bernstein’s plans, MAN developed a flexible motorised plough that could be used not only for ploughing but also for harrowing, harvesting potatoes, driving stationary machines or as a tractor. Presented at the DLG exhibition in 1921, it wins the highest award. It also stays in the lead in several other competitions, such as the Moosburg Power Plough Test in 1921 and the Comparison and Show Ploughing in Lower Franconia in 1922.
