The MF 6718 S tops the MF6700 S series, punching out a massive 200hp in a compact package. The six new models in series are powered by the very latest AGCO Power 4.9-litre, four-cylinder engine. This generates maximum power from 120hp to 175hp, with engine power management (EPM) boosting output on all models – up to 200hp on the MF 6718 S.
The tractor has a 2.67m wheelbase and a turning radius of 4.75m. This makes it the most manoeuvrable 200hp agricultural tractor available, according to the manufacturer.
Engine development
The four-cylinder AGCO POWER engine delivers more power and torque for high performance at lower engine speeds. MF says maximum power is developed at a low 2,000rpm, for optimum economy, and EPM, which is available on all models and across all transmission choices, boosts power by up to 25hp.
The engine generates high levels of torque at 1,500rpm, delivering pulling power, which is further boosted by EPM. MF states that this is particularly useful for transport duties, allowing the tractors to pull away with heavy loads and maintain momentum on the road.
The engine complies with Stage IV (Tier 4 final) emissions regulations using maintenance-free selective catalytic reduction (SCR) and a diesel oxidation catalyst (DOC) system with an electronic waste-gated turbocharger.
The design houses the catalysts in the oval-shaped exhaust and the DOC under the bonnet. MF says this gives the 6700 S tractors superb visibility to the front and sides. The 600-hour service intervals on the new range are 20% longer than previous designs. This will reduce overall running costs, according to MF.
Transmission choice
For the first time, the continuously variable Dyna-VT is now available on the 130hp MF 6713 S model and upwards. This will make it attractive for some farmers needing the flexibility of forward speed and PTO operation. The latest Eco Dyna-4 transmission provides 40km/h at engine speeds as low as 1,850rpm. Dyna-6 and Dyna-4 transmissions now provide an AutoDrive pedal mode. This changes gears automatically, according to the engine load and speed.
The MF 6700 S tractors weigh 500kg less than their equivalent six-cylinder models. Massey Ferguson’s Speedsteer increases the steering ratio, minimising the number of steering wheel turns needed to make a turn.
PTO and hydraulics
Depending on the model, buyers can choose from a wide PTO speed choice, including 540/1,000rpm with a flanged PTO and 6/21 spline shafts at all levels. Electronic control is standard for Dyna-VT versions. The standard Eco PTO can be specified with mechanical lever or full electronic controls on Dyna-4 and Dyna-6 transmission tractors.
Hydraulics on the MF 6700 S range are designed to handle the demands of most modern implements. Flow rates of up to 190l/min are available from the load-sensing system. Up to five rear hydraulic valves can be specified on all Dyna-VT models and all rear couplers are equipped with decompression levers.
Front-mounted implements are catered for with up to two independent front hydraulic valves plus a dedicated front linkage valve. A new rear power-beyond function is available for high-tech hydraulically driven implements equipped with independent flow control valves, such as potato planters and sugar beet harvesters. Rear linkage lift capacity is up to 9,600kg on Dyna-VT models (compared with 8,600kg on the MF 6600 series).
Loader options
Tractors can be ordered loader-ready, requiring just the fitting of the loader beams and implement. MF says the compact dimensions, power, visibility and high hydraulic capacity make the 6700 S the perfect loader tractor, and that the optional Visioline roof option gives more vision when loading at height.
Massey Ferguson’s 900 front loader can now be specified with a third live service, a clever addition to the loader hydraulic control that enables the operator to open/close a grab and tip an implement at the same time.
Cab comfort
MF 6700 S operators benefit from the same space found on the existing MF 7700 and MF 5700 SL ranges. These are now equipped with a new active mechanical cab suspension, with continuous damping control (CDC) for extra comfort. MF says this reduces heave/pitch and roll movements, reacting according to vehicle behaviour to provide optimum comfort to match all terrains and conditions.
