Dyna-4 MFs have French connection
Added performance, control and comfort are promised with the addition of the slick-shifting Massey Ferguson Dyna-4 transmission to the 100hp 5710 and 110hp 5711 tractors.
Dyna-4 is familiar to users of MF’s higher-spec 5700 S models up to 130hp and 6700 S machines from 120-150hp as a four-speed powershift on a four-range gearbox.
This results in a 16-speed transmission that offers good speed control variability, with the four-step powershift being available in reverse as well as forwards through the power shuttle.
The newcomers are part of Massey Ferguson’s Global Series project to create a new mid-range platform and are built in the Beauvais plant in France where Francesco Quaranta, head of MF’s European sales, marketing and product management team notes the “class-leading control efficiency” of Dyna-4 on the “workhorse” tractors.
A creep option is available for extra-slow speeds to suit cattle feeding and bedding applications, along with AutoDrive, which the operator can engage in the field to leave power-shifting decisions to a computer.
As well as easing the operator’s workload, comparative tests have shown AutoDrive can outperform an operator in terms of overall performance efficiency and fuel consumption.
A further option combines clutch and brake operation, so the tractor can be brought to a halt using only the brake pedal and set in motion again just by released the brakes.
That allows the driver’s left leg to take things easy when the tractor works with a loader or round baler, which both involved repeated stop-starts.
Surprisingly for tractors of this size and specification, the MF 5700 Dyna4 newcomers can also be had with cab suspension comprising spring-assisted shock absorbers for the rear mounts.
