World’s first 200hp four-cylinder tractor

Massey Ferguson has introduced the MF6700S series, which includes the world’s first 200hp, four-cylinder agricultural tractor
The MF6700S is powered by a new 4.9L, four-cylinder AGCO Power engine, which Massey says delivers exceptional power and torque for high performance at lower engine speeds.

Maximum power is developed at a low 2,000rpm, for optimum economy.
Engine power management (EPM), which is available on all models and across all transmission choices, boosts power by up to 25hp, taking the top model, the MF6718S, to 200hp – making it the most powerful four-cylinder tractor on the market, the company says.
“High levels of torque are generated at just 1,500rpm, delivering immense pulling power, which is further boosted by EPM,” a company spokesperson said. “This is particularly useful for transport duties, allowing the tractors to pull away with heavy loads and maintain momentum on the road.”
"The engine complies with the strict Stage IV (Tier 4 final) emission regulations using a maintenance-free, selective catalytic reduction (SCR) and a diesel oxidation catalyst (DOC) system with an electronic waste-gated turbocharger.
On top of the engine’s optimum fuel economy and the maintenance-free emission regulation system, running costs are further reduced by the 600-hour service intervals – 20 per cent longer than previous designs."
Transmission choice
The MF6700S series is available with a choice of Massey Ferguson’s leading transmission technology.
For the first time, the continuously variable Dyna-VT is now available from the 130hp MF6713S model upwards. “This delivers ultimate control and economy by providing precise regulation of forward speed, while minimising the engine rpm, ensuring the tractor always operates at optimum efficiency and economy,” the spokesperson said.
“The latest 40kmph Eco Dyna-4 transmission now offers further efficiency, providing 40kmph at engine speeds as low as 1,850rpm.”
Dyna-6 and Dyna-4 transmissions now provide an AutoDrive pedal mode. In the ‘automatic’ setting, this changes gears automatically, according to the engine load and speed. As well as easing operation, this also selects the best setting for performance and fuel economy, according to Massey.
Power, agility and economy
Built on a 2.67m wheelbase, the MF6700S tractors weigh 500kg less than their equivalent six-cylinder models. Coupled with their powerful engines, this produces an unrivalled power-to-weight ratio that results in a light footprint and optimum economy, according to the company.
It says the MF6718S offers the tightest turns available from a 200hp agricultural tractor. This is thanks to its compact design and sculpted front frame delivering a turning radius of just 4.75m, even when fitted with the Integrated Front Linkage System (IFLS).
“Its unrivalled four-cylinder power, manoeuvrability and agility puts the MF6700S in a class of its own,” according to Massey Ferguson. Its new ‘S Effect’ takes maximum four-cylinder engine output to 200hp (with EPM) for the first time in the MF6718S.
“The compact, powerful engine, a 2.67m wheelbase and a turning radius of just 4.75m also makes the MF6718S the most manoeuvrable 200hp agricultural tractor,” a spokesperson said. “With an exceptional power-to-weight ratio, the tractor combines the highest performance with optimum economy.
“Light and nimble for loader operations, the MF6700S series also provides the strength, hydraulic power and lift capacity for heavy-duty fieldwork.”
Six models
The six new models in the MF6700S Series are powered by the latest AGCO Power 4.9L, four-cylinder engine. This generates maximum powers from 120-175hp, with EPM boosting output on all models.
“Massey Ferguson invented the concept of the high-power, four-cylinder tractor, with the original MF6600 breaking new ground and creating a completely new class of 150hp+ tractors. Now, with the ‘S effect’, we are further advancing performance in this sector up to 200hp on the MF 6718 S,” said Campbell Scott, Massey Ferguson director marketing services.
“The advanced engine develops its maximum power at just 2,000rpm and generates maximum torque at 1,500rpm, which means it delivers exceptional fuel economy combined with superb pulling power – and with plenty in reserve. This provides users with the operating benefits associated with larger, longer and heavier six-cylinder tractors, but in a compact and extremely light machine,” he said. “The only comparison with the MF6600 series is its looks. The MF6700S series contains considerable changes and new developments in engine design, transmission choice, hydraulic output, four-speed power take-off (PTO) and superb cab comfort,” he added.
