A total of nine models offer maximum powers of 140 hp to 255 hp, providing a choice of three transmissions and three levels of specification. Engine Power Management (EPM), which provides up to 25 hp extra power, is standard on all models taking maximum power to 280 hp on the flagship MF 7726 model. “The MF 7700 Series continues Massey Ferguson’s drive to develop dependable, straightforward, low maintenance tractors that provide efficiencies across all farming operations,” says Campbell Scott, Director Sales Engineering and MF Brand Development. “These new tractors benefit from the excellent pedigree established by the MF 7600 Series which won Machine of the Year, Tractor of the Year Golden Design Award as well as Gold Medals and numerous accolades across Europe. It has also established a proven track record and gained strong respect from customers,” he adds. Massey Ferguson has further refined this winning design and added new features that boost comfort and control, leading to even greater performance and productivity to further reduce overall ownership costs.

In 2008, Massey Ferguson was the first tractor manufacturer to introduce Selective Catalytic Reduction (SCR), recognised as the most straightforward, reliable and economic method of achieving increasingly strict emission regulations. The MF 7700 Series tractors continue to be powered by six cylinder, AGCO POWER 6.6 litre and 7.4 litre engines, equipped with the latest SCR technology, which remains maintenance free. There is no Diesel Particulate Filter (DPF). Larger catalysers remove more pollutants, but remain contained neatly within the same-sized enclosure, retaining the same excellent forward visibility. Engine Power Management (EPM) provides up to an extra 25 hp to improve efficiency and performance on the road and in the field. This is standard on all models from the 140 hp, MF 7714 to the new flagship 255 hp, MF 7726 – including those equipped with DynaVT transmission. The Engines feature a new Engine Control Unit (ECU), with higher fuel injection pressure, an electronically controlled wastegate turbocharger and a new throttle valve.

Unrivalled transmission choice

The MF 7700 Series offers an unrivalled choice of transmissions which are perfectly matched to the engines and transmit more power to the wheels for maximum output. The slick, easy to use Dyna-VT is available across the range from the MF 7715 upwards. Dyna-VT provides stepless speed changes and allows operators to select any combination of engine speed and forward speed to optimise output and the work quality. Engine revs can be set for the precise combination of power and torque required for the best work quality, resulting in optimum fuel economy and lower noise. While offering the ultimate in sophisticated transmission operation, the Dyna-VT retains MF’s ‘family feel’ and straightforward, intuitive controls. This includes the familiar Power Control lever on the left of dashboard, under the steering wheel, which is a feature on all tractors, regardless of transmission. The rugged and well  proven Dyna-6 transmission provides clutchless operation of six speeds in four ranges providing a total of 24 forward and 24 reverse speeds. Economy is further improved by the Super Eco Dyna-6 transmission for the MF 7719 to MF 7726 models, which provides 40 km/h achieved at a remarkably low 1,500 engine rpm. The highly efficient Dyna-4 transmission is standard on the MF 7714 and an option on the MF 7715 tractors. This offers 16 forward and 16 reverse speeds with four Dynashift (powershift) speeds in four ranges and allows road speeds of 40 km/h to be reached at an economical 1,880 rpm. Electro-hydraulic control also provides clutchless range changes. AutoDrive is a performance enhancing option on Dyna-4 and Dyna-6 and provides automatic changing of the six steps in fieldwork, as well as the ranges when in transport. Using the SIS screen, operators can set the engine speed at which AutoDrive will automatically change gear and with the new ‘Auto’ setting the transmission will also automatically select the most appropriate gear. All models with Dyna-VT transmissions are equipped with a four-speed PTO system providing of 540, 540E, 1,000 and 1,000E speeds. A brake-activated neutral feature is standard on all the transmissions, simultaneously operating the clutch as the brake is pressed – easing the load on the operator, while increasing efficiency and convenience, particularly in loader operations.

Hydraulic power and control

MF 7700 Series tractors provide the hydraulic flow and power to handle and control modern implements with ease and efficiency. A new load-sensing, closed-centre pump delivers 190 litres/min on the new Dyna-VT tractors, while the MF 7719 to MF 7726 Dyna-6 models provide 110 litres/min as standard with the option of 150 litres/min. All load-sensing models have decompression levers on the spool valves for easy coupler connection and removal. Up to five rear spool valves can be specified. When a front linkage is specified additional valves are fitted – one for the front linkage and one or two for front couplers.

New reliable front axle suspension

Massey Ferguson has designed and built a new front axle suspension system specifically for the MF 7700 Series to further boost operator comfort as well as increase dependability. Completely maintenance free, the suspension employs double acting rams, which provide 30% more travel than previous designs. The rams are attached directly to the axle and the front axle support. This straightforward set-up, without any complex linkages, combines comfort with reliable operation. At the same time it also increases manoeuvrability. Up front there are also a new mono blocks providing 900 kg or 1,500 kg of ballast. These compact blocks restrain the overall tractor length and also offer the facility to fit further wafer weights.
