Massey Ferguson is extending its highly successful MF 7400 Series with the addition of the 225hp, MF 7497 and 240hp, MF 7499 models. Both are equipped to a high specification and feature the output enhancing Dyna-VT continuously variable transmission.
The new tractors, which will be introduced at the Agritechnica Show in Hanover on 10th-14th November 2009 provide the power and versatility required by modern, professional farmers and contractors.
"The MF 7400 Series is already the professional’s choice. These new models combine the power of the 7.4 litre, SISU AGCO POWER engine with the precision of the Dyna-VT transmission, which together offer optimum productivity and economy along with comfort from the exceptionally quiet cab.
"The higher power, strength and excellent weight distribution of the new MF 7497 and MF 7499 make them very versatile tractors, capable of high work rates in a range of modern operations," explains Laurent Pernin, General Marketing Manager for medium to high hp tractors.
"They are particularly manoeuvrable for their power and, fitted with the Integrated Front Linkage System, they are the perfect host for front and rear mower, drilling and spraying combinations. The tractors feature a high level of automation as standard providing many output-enhancing features that improve control, relieve the strain on the operator and ultimately ensure the work gets done faster and more economically."
Two new models:
MF 7497 – 225hp max
MF 7499 – 240hp max
• Advanced AGCO SISU POWER, 7.4 litre engines produce greater pulling power at low engine speeds for superb economy and high work rates
• Dyna-VT, continuously variable transmission allows operators to optimise every operation with any combination of forward speed and engine revs. Unique left-hand Power Control lever eases operation
• New standard Dynamic Tractor Management (DTM) system minimises engine speed according to load to further improve economy
• Rugged front axle casting provides exceptional manoeuvrability and permits close coupling of Integral Front Linkage System (IFLS) with PTO option
• QuadLink front axle suspension option offers extra comfort and traction without compromising manoeuvrability. Hydralock provides true four-wheel drive
• Sensitive load-sensing hydraulics with electronic linkage and spool valve control
• Sector leading spacious cab offers very low noise levels, high comfort and ease of control with adjustable Dual-Stage pneumatic suspension option
• Datatronic 3 option for complete monitoring, automatic control and straight-forward job recording with SD card data transfer
• Auto-Guide precise auto-steering option
Large capacity engine for greater torque and power
The new MF 7497 and MF 7499 are both powered by the well proven AGCO SISU POWER, 7.4 litre capacity engine. Equipped with four valves/cylinder and common rail fuel injection these reliable engines are renowned for their fuel efficient operation.
At 7.4 litres, the engines have a much higher capacity than others in the sector, which allows the tractors to not only achieve higher pulling power and torque at lower engine rpm, but also maintain this output across a wide operating rpm range. This improves both productivity and economy because the engine does not have to work so hard to achieve the power and torque, which saves fuels, cuts noise and reduces wear.
Dyna-VT for optimum work quality and economy
Dyna-VT, based on the world’s most proven continuously variable transmission, is highly efficient and transmits maximum engine power to the wheels, as well as offering ultimate economy and control.
Its ability to allow users to set any combination of forward and engine rpm speeds means Dyna-VT provides optimum control, work quality and exceptional productivity. It provides speeds from 30m/hr to 40 or 50km/hr*, in just two ranges, unlike other manufacturers’ designs that use four ranges.
Dyna-VT has a range of automatic operating modes, controlled by a foot pedal or a lever, as well as Massey Ferguson’s unique Power Control lever. Mounted on the left-hand side of the dashboard this lever allows operators to change direction, adjust speeds up and down and select ’active stop’, while leaving the right hand free to operate other functions.
* Top speed depends on market
Dynamic Tractor Management (DTM) further boosts efficiency
The new, fully adjustable Dynamic Tractor Management (DTM) system is an electronic link between engine and transmission that adjusts the engine speed according to the load to minimise rpm for optimum economy.
The DTM system manages the engine speed automatically and works in both pedal and lever modes to consistently maximise productivity whilst at the same time minimising fuel consumption.
Strength and versatility from integrated monocoque chassis
MF has developed a new front axle support casting that assists in mounting a new fully Integrated Front Linkage (IFLS) and PTO option to the MF 7497 and MF 7499 models.
Close-coupling of the 4,000kg capacity front linkage with IFLS provides a neat, compact mounting for additional strength without affecting the turning circle of the tractors, which are exceptionally manoeuvrable for their size. Combining operations increases productivity and saves time and fuel.
The ingenious front Dual Control system raises and lowers the implement automatically, using a distance-based system, which considerably eases the driver’s workload when turning.
Front suspension for speed, safety and comfort
The 50km/hr* top road speed, high engine power, superb Dyna-VT transmission makes the MF 7497 and MF 7499 ideal for heavy haulage and roadwork.
The addition of the QuadLink front suspension option not only permits high speeds to be achieved with great comfort, but also in complete safety. The suspension can be switched on or off and automatically compensates for the additional weight of an implement on the front, providing the same movement up and down without impeding the axle oscillation or turning circle.
In the field, QuadLink is also shown to improve traction by up to 20%. Hydralock, a standard front axle feature, offers genuine four-wheel drive (not three), by locking the front and rear axles together for optimum traction.
*Top speed depends on market.
Sensitive hydraulics with precise control
A 110 litres/min, load-sensing hydraulic system is standard on the new Massey Ferguson MF 7497 and MF 7499 tractors (150 litres/min is an option). The renowned Electronic Linkage Control provides precise operation and quick reactions, for higher productivity from increased traction with lower wheel slip and tyre wear.
Electronic operation of the auxiliary hydraulics offers proportional spool valve flow control for accurate, convenient control. The SMS armrest-mounted, joystick controls two spool valves for convenient and accurate operations of, for example, loaders. A Power Beyond port enables simple and easy use of implements equipped with hydraulic motors.
The Datatronic 3 option provides auto-operation in the comprehensive Headland Management System, which memorises functions and repeats sequences at a touch of a button. Further automation comes from the optional front and rear Dual Control, Trailed Implement Control plus the facility to memorise flow and timing of spool valves.
Trailed Implement control is a unique system that, with the addition of a sensor on implement, provides draft control (based on monitoring wheelslip) for trailed and semi-mounted equipment.
Dual Control simplifies operation of front- and rear-mounted combinations by automatically raising and lowering both implements at pre-set distances. This can also be incorporated into Headland Management.
