The new RazorBar rotary disc headers for the Massey Ferguson WR9900 self-propelled windrowers will form better windrows and be easier to service, the company says.

Comprising the 4m MF 9313D and the 4.9m M9316D models, the new designs of the 9300 range replace the MF9296 headers – the last of the MR9200 Series.

Massey Ferguson says the new design has a number of features to help it process a crop through the mower conditioner quickly and create wide, flat windrows that dry quickly.

New belt-drive stub augers at the end of the header improve crop feeding into the conditioner rolls, while fully enclosed crop conveyors outside the augers prevent crop wrapping and build-up.

Moving the crop quickly from the outside discs to the conditioner means a cleaner cut, less chance for double cutting, better windrow formation and less opportunity for leaf damage, Massey Ferguson says.

A self-adjusting spring tensioner on the new drive-belt system helps operators set the optimum belt tension, while a new side panel gives easier access to the drive belts on the auger headers.

That said, the new headers keep some features from the 9200 Series, including its large tandem hydraulic drive pumps and the RazorBar disc cutterbar, which it says is the strongest and most durable in the industry.

It also keeps the TwinMax double conditioning system, which uses steel-on-steel conditioners to crimp hay and fodder every 2–5cm rather than crushing it, reducing drying time while allowing the hay and forage to retain vital nutrients.

Massey Ferguson says the new headers will help farmers get better quality hay at harvest time.

"The higher the quality, the better the feed value and efficiency for livestock producers and the higher the price at market," the company says.
