The WR9800 series includes over a dozen proprietary features, developed in direct response to feedback received by working hay producers. One such feature is the industry-exclusive rear-steer option for positive windrower steering from the rear axle to provide you with better operator comfort and increased transport speed; you can even tow a draper head. The plug & play Auto-Guide™3000 guidance system provides you with the most advanced GPS steering available and up to speeds of up to 17.5 mph. You have instant access to fuel economy, performance, header flotation settings, diagnostics and troubleshooting with the FieldMax monitor included on the WR9800 series.


With the WR9800 series of windrowers there is no need for rotary screen cleaners thanks to the V-cool System that features an auto-reverse fan. You can go longer with these windrowers between fuel fill-ups as these windrowers feature one of the highest capacity fuel tanks in the industry as well as SCR fuel saving technology. You can go up to 2 days without refueling the WR9800 series.

These Massey Ferguson windrowers are quite versatile and can fulfill a number of jobs for you. With a 5300 header, the WR9800 series provides you with high capacity swathing while a sickle or disc header turns these windrowers into quality hay machines.

Each model comes with Massey Ferguson’s triple windrow attachment which allows operators to merge up to three swaths into one. This is great for forage harvesting applications. Electro-hydraulic steering provides you with adjustable steering sensitivity for a more precise, quicker response.
