“The MF Centora, with its unique eight straw-walker separation system, is renowned for being one of the largest capacity conventional combines on the market,” MF powered harvesting manager Adam Sherriff said. “It delivers the capacity and great straw quality many users demand, along with very cost effective operation. For next season both models will also benefit from the addition of advanced technology first developed for the high capacity MF 9280 Delta hybrid combine.”
The latest Agco Sisu Power engines, with Generation 2 selective catalytic reduction (SCR) exhaust after-treatment, develops a maximum power of 379hp on the MF 7280 Centora plus a further 25hp power boost. The MF 7282 Centora has a maximum power of 404hp. The MF Delta power remains at a maximum 500hp.
By treating the exhaust gases after combustion the SCR process does not add any complexity or additional cooling packages required by mechanical systems. The latest Generation 2 system now also employs a diesel oxidation catalyser that includes the AdBlue dosing injector nozzle. From here exhaust gases receive further treatment by SCR Catalysers and ‘slip cats’.

| MF’s two Centora models have received a host of updates for 2012. |
A new engine drive plate is an important addition to both Centoras. Developed for the Hybrid combine’s seven-cylinder engine, the new unit ensures smooth and consistent power delivery. By removing shock loads, the new plate will increase driveline durability.
To further increase capacity on the Centora combines, the concave can now open wider – to 40mm – to handle extra throughput. This is set and adjusted via the DataVision screen in the cab. A wide concave setting not only allows more crop to flow through, but on easy-to-thresh crops, such as oilseed rape, it also helps cut power and fuel consumption. Opening up the concave in other small-grain crops, such as wheat, prevents over-threshing and provides more crop-on-crop threshing to separate more grain from the straw.
Increasing the grain preparation pan angle and motion now increases the capacity to deliver more grain to the pan and improve the sample in the tank. A greater grain pan incline allows for more material flow from the main concave. Also, a much more aggressive shaking motion speeds up the transportation of the grain from the concave to the cascade cleaning system.
The new rear axle fitted to 2012 Centora and Delta combines cuts the turning radius to 5.5m, which will speed up headland turns and increase efficiency. At the same time the axle has been strengthened, while new steering geometry, larger steering cylinders and an extra 25 per cent torque applied to the system eases steering.
As well as the new tight-turning axle and new engine technology, the MF Delta combines benefit from a host of changes regarding serviceability for the 2012 season. A new engine compartment layout improves accessibility and includes a built-in hand rail for safety.
The air cleaner, hydrostatic reservoir and coolant tank all are repositioned to offer better access for the operator for servicing purposes. Also for the operator is a new step design to the cab with self-cleaning treads and quick position change for travelling on the road.
