John Deere has announced it is launching two new six-cylinder tractor models, the 6230R and 6250R, rated at 230hp and 250hp (97/68 EC) respectively, which are designed to meet the needs of contractors and arable farmers and will complete the lineup of John Deere 6R Series tractors from summer 2017.
Thanks to an engine boost of 50hp with intelligent power management (IPM), the flagship 6250R tractor will provide up to 300hp when required. With a very light vehicle weight of 9.3 metric tons, the 6250R delivers more power than any other tractor in this weight class, along with an unrivalled power density of 31kg/hp. The high maximum permissible weight of 15 metric tons also allows a 5.7-metric ton payload, which means the tractor is able to transport heavier loads.
Both new tractors are powered by a 6.8-liter PowerTech PSS engine with dual turbochargers and advanced DPF and SCR technology, which responds very quickly to changing loads while consuming less fuel and meeting demanding Stage IV emission standards.
The upgraded AutoPowr transmission delivers maximum efficiency, with 100% mechanical power available at 3.5km/h for heavy draft operations, 11km/h for light draft work, 22.5km/h for heavy transport and 47.2km/h for light transport duties. Once running at maximum road speed, rpm automatically drops and 50km/h is maintained at 1630rpm and 40km/h at 1300rpm, which results in lower fuel consumption on the road.
The tractors also feature an all-new CommandPRO joystick, which introduces a new dimension in ergonomics and versatility to John Deere tractors. Top speed can be reached with just one push, and 11 programmable buttons are available for the hitch, PTO, SCVs, AutoTrac controls etc. The functionality of CommandPRO allows the tractor to be controlled from top speed to zero with a simple push or pull of the joystick, and lower speeds from 0 to 2km/h can be achieved with the creeper control function. Both the joystick and pedals can be operated at the same time, and there is no need for an external ISOBUS joystick as the driver can also operate the tractor and ISOBUS functions simultaneously.
Equipped with a pressure and flow compensated hydraulic system, the new 6R Series tractors deliver a powerful maximum flow of 160 liters/min at 1500rpm. This also saves fuel, even in the most demanding hydraulic applications. Up to six SCVs with individual pressure-relief levers have been grouped together for easier access, and new lift capacities are 10.4 metric tons on the rear hitch and 5 metric tons at the front.
The 6230R and 6250R tractors also feature a high level of operator comfort. The intelligent hydro-pneumatic cab suspension (HCS Plus) system offers more driving comfort and isolation from noise and vibration. Better traction and up to 10% more power applied to the ground are provided by the new self-levelling TLS Plus triple link suspension system on the front axle.
