Massey Ferguson: Lamma debut for eight-straw-walker Centoras

The new Massey Ferguson Centora range are the only combine harvesters on the market equipped with eight straw-walkers, with the two models – the 378hp, MF 7280 and 413hp, MF 7282 – both available in full AutoLevel versions. 
Along with Massey Ferguson’s unique eight-straw-walker system, which offers a third more separation capacity compared with six-walker combines, the Centora range has a highly efficient, gentle conventional threshing system. This is renowned for producing exceptionally clean grain samples with low power and fuel consumptions.
The new Centora combines are fitted with the MF Powerflow table as standard. Tried and tested with more than 30 years experience in the field, the Powerflow table will lift outputs by up to 73% in rape; 15% in wheat and 12% in barley, without any need to make any alterations or adjustments when switching between crops. A low-cost rape auger option, further improves performance in tall crops.
AutoLevel control allows the table to follow ground contours and comes with automatic Cutting Height Control that provides three height options at the touch of a button. Auto Reel Speed maintains the operator’s set ratio between forward speed and reel speed to ensure even feeding at all times.
Massey Ferguson’s Constant Flow system is standard on the MF7282 and MF7282AL Centora combines and is a genuine, output-enhancing option on the MF7280 and MF7280AL, which can boost capacity by up to 15% in many crops and conditions.
Crops are threshed by a 1,680mm wide, 600mm diameter Hi-Inertia threshing cylinder. Eight rasp bars are mounted on 7mm thick backing bars with the action starting immediately the crop enters as it passes over the pre-threshing rub bar in front of the electrically-adjustable concave.
A rear beater then moves the crop into Massey Ferguson’s Twin Speed Rotary Separator that increases the straw volume and opens up the mat to separate out any trapped grain before spreading the straw onto the straw-walkers.
Providing a total separation area of 6.68m² the unique eight-walker design provides a third more capacity than six-walkers with more action to turn, tease and agitate the straw mat to release any trapped grains.
Centora combines use a true cascade cleaning system that features two separate grain pans. Unlike augers, which transport the grain, the grain pans transport, clean and separate at the same time – using the well-proven shaking action to move the chaff and straw to the top while the grain stays underneath. A separate rethresher unit, which is a small drum and concave, processes any returns, feeding the grain back to the pan.
Grain tank capacity on the MF7282 Centora is 10,500 litres and 9,500 litres on the MF7280 and AutoLevel models. All Centora combines unload with a high discharge turret unloading system, which offers fast unloading, over any position in the arc and into the highest trailers to maximise efficiency.
The latest generation Agco Sisu Power Citius engines develop a maximum power of 378hp on the MF7280 and MF7280AL machines and 413hp on the MF7282 and MF7282AL models. A Powerboost system automatically increases power when the combine is unloading as well as ensuring there is more than enough power for an industry-leading ‘min-till’ chopper, fitted as standard on all machines.
The top class cab features climate control as standard, armrest mounted controls and an unobstructed view of the cutting table through the large area front screen. The Datavision II control and monitoring system is standard, providing touch-screen operation of the entire combine as well as providing grain loss monitoring, yield and moisture sensing and, of course, yield mapping when linked to the GPS system.
