A John Deere 6250R tractor equipped with a Kuhn four-rotor Gyrorake GA 15131 with a working width of 14.7m has set a new windrowing world record, raking 188.9ha of grass on four different fields in only eight hours. The tractor’s light weight, strength and ‘smart’ features kept productivity at the highest level, even in hilly conditions.
The world record was set on a typical dairy farm in the Central Jutland region of Denmark. The DLG Test Centre validated the record after carrying out several spot measurements during the attempt. Forage quality was confirmed, as well as an average output of 23.6ha per hour.
The John Deere 6250R has therefore proved once again to be the perfect partner when it comes to setting new performance levels. Thanks to the additional horsepower delivered with Intelligent Power Management, this flagship 6R Series tractor provided up to 300hp (maximum power with IPM) in the hilly field conditions.
At 9.3 tonnes empty, the tractor delivers more power than any other in this weight category along with an unrivalled power density of 31kg/hp. Combining this with the proven AutoTrac guidance system, intuitive Gen4 CommandCentre console and ergonomic CommandPRO joystick enabled the 6250R to achieve a maximum operating speed of 22kph for a record high productivity level of 32ha per hour.
The tractor was driven by Mikael Skeldal, who runs the dairy farm with his family. He says he benefited from the CommandPRO joystick and appreciated both its ISOBUS compatibility to operate the rake as well as the ability to monitor operations via the Kuhn CCI 1200 terminal and WTK joystick. This allowed him to see the work in progress and optimise the rotor adjustment without any interruption to the record attempt.
