New Power for MF Tractors

Tier III-compliant power plants and new transmissions boost tractor power.

Massey Ferguson 6400 and 7400 Series tractors get a boost this year from new Tier III-compliant power plants and a pair of new transmissions to take full advantage of the new power.

NEW POWER TRAINS: Massey Ferguson's 6400 and 7400 Series tractors get new engines and transmissions this

year for fuel savings and more efficient torque handling capacity.

The new engines are designed to burn diesel fuel cleaner and more efficiently, while the Dyna-VT CVT transmission on the 7400 Series (100-155 powertakeoff horsepower) and the Dyna 6 transmission on the 6400 Series (100-180 hp) are tuned for efficient use of torque in transit and under load.

In one MF test, a 7400 Series with 155 hp burned a quarter gallon of fuel per acre running a 9-foot disc at 12.9 kph. The clutchless CVT (continuously variable transmission) has demonstrated significant fuel savings over powershift transmissions of the same capacity.

The Dyna-6 gearbox offers six powershift ratios that can be shifted up or down at full load in four ranges for 24 speeds forward and reverse.
