New duo expands MF 7400 range into 200+hp category
Two new top-end models have been added to Massey Ferguson's 7400 series, extending the range into the 200+hp sector. Previously, it was a six-model range, starting with the 125hp (135hp maximum power) 7465 up to the 190hp (203hp maximum power) 7495.
Targeted at professional farmers and contractors, the new additions -- 7497 and 7499 -- bring 205hp (225hp maximum power) and 220hp (240hp maximum power) to the table respectively.
Powering both models is the Finnish-made Sisu engine. This is a 7.4-litre unit configured to produce the desired horsepower for each model. Four valves in each cylinder and common-rail injection keep it emission- and fuel-friendly.
According to MF, the engines, at 7.4 litres, have a much higher capacity than others in the sector, which they say achieves higher pulling power and torque at lower engine RPM. They claim this saves fuel, cuts noise and reduces wear.
Interest in these models has been driven by the standard MF, Dyna-VT continuously variable transmission. Based on the Fendt unit, many would argue the MF-controlled unit is simpler to drive.
The further you push the VT lever forward the faster it goes, and a left-hand shuttle lever under the steering wheel gives you forward and reverse, and allows the operator to increase/ decrease speed as well, which helps free up the right hand for other duties.
There is a range of automatic modes and foot pedal speed controls as well.
MF's dynamic tractor management (DTM) system allows communication between the engine and transmission, and adjusts the engine speed according to the load on the engine to minimise its RPM for optimum fuel economy.
