Combines for the 21st century

It has been more than a hundred years since Daniel Massey perfected the machine that was to revolutionize harvesting. Since then MF has never stopped breaking new ground in combine harvester technology.

Today MF presents a range of combine harvesters, which incorporate the very latest in technological features, designed to get the best both from the crop and the machine. They are comprehensive in their appeal. They feature massively proportioned cylinders, straw-walkers and sieves for increased capacity and longer life. Powerful engines provide efficient performance in the most arduous1 conditions and with Data vision TV monitor plus hydrostatic transmission no crop is beyond their capabilities. The machines have excellent ground clearance. They are sure footed on hillsides even when conditions are not ideal.

The cabs of the MF combines have been specially designed for the driver's safety, well-being and ease of operation.

The controls are grouped together on a console2 at the operator's right hand. No more handles, rod and linkage controls and hydraulic spool3 blocks in the cab; just electrical control buttons4 within hand's reach. With a single multi-functional lever the operator can control forward movement, cutting height, reel height and speed, reel fore and aft5 positioning and the table throw out clutch. The whole combine responds to the movement of the operator's right hand as if he were piloting an airliner.
