X Series, John Deere expands its range
John Deere adds two new models - the X9 1000 and X9 1100 - to its combine range. The X-Series is designed to deliver top performance in difficult conditions and with high volume and moist straw. The X9 1100 - explains the manufacturer in a technical note - can harvest wheat up to 100 tonnes per hour with a grain loss of less than 1%. The strength of this machine is its ability to automatically adapt its operating parameters to changing working conditions. The new X Series combines are equipped with 3.5-metre-long XDS modular rotors with a separation area that uses finger-like design elements to separate even the last grains from the straw, thus improving yield especially in less than optimal harvesting conditions. As the manufacturer goes on to specify, the 7 m2 Dyna-Fl XL cleaning system has 36% more surface area and, combined with the new ventilation system, offers 45% more cleaning capacity than the S Series combines. Another plus of the X Series is the feeder neck, one of the widest on the market, which significantly improves crop flow and increases harvesting capacity.
The ProDrive XL transmission also features a highly innovative profile. ProDrive XL uses a dual pump technology that drives both pumps when the machine starts to deliver maximum torque. When forward speed increases and torque demand decreases, the flow rate of the second pump is reduced, reducing power absorption and fuel consumption.
Thanks to this technology and the 1,250-litre tank (the Fast Fuel system allows it to be completely filled in just over two minutes), the X Series combines can work for fourteen hours without refuelling, according to the manufacturer. Powering John Deere's combines is a 13.6-litre PowerTec six-cylinder diesel engine that develops up to 700 Hp (515 kW) and uses a sturdy belt drive system to further reduce fuel consumption (20% less according to John Deere) and offer more torque at lower engine speeds.
