Massey Ferguson has announced the addition of a continuously variable transmission option for its best-in-class MF 5S series tractors.
New MF 5S Dyna-VT models complement existing Dyna-4 and Dyna-6 versions and have been added to the line-up to meet growing demand for extra versatility and comfort from farmers. “Our multi-award-winning MF 5S series models have a strong reputation as the best loader tractors, but their capability, flexibility and high specification mean they are increasingly selected for grassland and arable field tasks too,” explains Jérôme Aubrion, Director Marketing Massey Ferguson, Europe & Middle East. “The new Dyna-VT transmission option adds even greater appeal to this successful series, and the extra comfort, efficiency and ease of use will be welcomed by customers and dealers worldwide.”
All five MF 5S-series models from 105hp to 145hp with mid-range Efficient and top Exclusive specification are available with Dyna-VT transmission. Those buying base Essential specification machines have the choice of the Dyna-4 or Dyna-6 gearbox.
As well as the new continuously variable transmission, Dyna-VT models feature new front and rear axles, a new hydraulic system, and a new rear linkage and hitch.
Dyna-VT transmission has a single range of gears and allows stepless adjustment of travel speeds from 0.1 to 40kph. Speed control is by the foot accelerator pedal, the hand throttle lever or the Power Control lever, and the maximum 40kph can be achieved with the engine operating at a low and economical 1,550rpm.
For added convenience, two virtual speed ranges can be saved and selected using a switch on the Transmission Control Lever. Different start-off speeds for forward and reverse can be set, as well as two cruise control speeds in each mode.
The Dyna-VT transmission adds Parklock as standard. This automatically applies the parking brake through the Power Control shuttle lever and offers particular advantages for tractors used in frequent stop-start operations.
In fully automatic mode, the operator simply selects the travel speed by depressing the foot pedal. The tractor’s management system selects the most efficient engine revs and transmission drive ratio for the selected speed and conditions, and these are constantly optimised as the working load alters.
When working with PTO or hydraulic-driven implements, the required engine speed can be set and stored in the A and B engine speed memories while the operator adjusts the travel speed independently.
Virtual speed ranges allow even finer control. Rather than having the full range of speeds always available, the operator can create bespoke virtual ranges between any minimum and maximum speeds for a particular application. This increases controllability for activities such as loader work or baling, as the travel speed remains within the pre-set parameters and minor adjustments are easily made.
For tasks requiring frequent travel direction changes, the drive engagement rate can be set to suit the conditions. Gentler engagement is ideal for precise loader work on a hard surface for added driver comfort, also reducing tyre wear and risks of load spillage. More rapid engagement can be selected to speed up manoeuvring and reduce cycle times and for most field tasks an intermediate rate is ideal.
Dyna-VT provides significant benefits for both novice drivers and more experienced users. Automatic working modes ensure the engine and transmission operate together at maximum efficiency, while more advanced settings enable professional operators to prioritise extra fuel economy or achieve even higher work rates.
All MF 5S series Dyna-VT models share the same, 2,550mm wheelbase. This provides excellent stability for loader work, traction for field tasks, and enhances ride comfort for transport applications. The maximum 9,000kg gross vehicle weight and 41,000kg Gross Combination Weight rating* allow users to make the most of the new tractors’ capabilities. *(local restrictions may apply).
All five models come standard with 6,000kg rear linkage lift capacity. A load-sensing 110 litres/min hydraulic system ensures rapid cycle times for efficient loader operation and provides plenty of flow for the most demanding implements. With up to 41 litres of removable oil capacity, new MF 5S Dyna-VT models tip the largest trailers with ease.
As on other MF 5S-series models, a micro joystick on the Multipad controls the first and second valves. Third and fourth valves have either mechanical control on Efficient models, or finger type electronic control on Exclusive variants.
A three-speed PTO with 540, 540 Eco or 1,000rpm output is standard. The 540 Eco option provides fuel savings and reduces noise, and wear and tear by allowing implements requiring less power to be operated at an engine speed of only 1,560rpm.
Helping farmers achieve best possible efficiency and maximum productivity, the new MF 5S Dyna-VT tractors are all available with the full range of Massey Ferguson Smart Farming solutions.
MF 5S Dyna-VT models benefit from the same low costs of ownership as current Dyna-4 and Dyna-6 versions including 600-hour engine, and 2,400-hour transmission oil change intervals, and are backed by a generous factory warranty.
