John Deere adds new flagship tractors to 6R Series
Available from summer 2017, the two new range-topping 6cyl 6230R and 6250R models are rated at 230 and 250hp (97/68 EC), with a 50hp engine boost with intelligent power management increasing the output in the flagship 6250R to 300hp. Deere says the 9.3-tonne 6250R delivers more power than any other tractor in this weight class, along with an unrivalled power density of 31kg/hp. The maximum permissible weight of 15 tonnes also allows a 5.7-tonne payload, allowing the tractor to transport heavier loads.
Completing the 6R Series line-up, power to both models comes from a Stage IV 6.8-litre PowerTech PSS engine with dual turbochargers and DPF and SCR technology. The upgraded AutoPowr transmission provides 100% mechanical power availability at 3.5km/hr for heavy draft operations, 11km/hr for light draft work, 22.5km/hr for heavy transport and 47.2km/hr for light transport duties. Once running at maximum road speed, rpm automatically drops and 50km/hr is maintained at a fuel-saving 1630rpm and 40km/hr at 1300rpm.
The new CommandPRO joystick allows the tractor to be controlled from top speed to zero with a simple push or pull of the lever, and lower speeds from 0 to 2km/hr can be achieved with the creeper control function. Eleven programmable buttons are available for the hitch, PTO, SCVs, AutoTrac controls, etc, and both joystick and pedals can be operated at the same time. 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 two new 6Rs deliver a maximum flow of 160lit/min at 1500rpm. Up to six SCVs with individual pressure-relief levers have been grouped together for easier access, and lift capacities are 10.4 tonnes on the rear hitch and 5 tonnes at the front.
The company says the hydro-pneumatic cab suspension (HCS Plus) system improves operator comfort, while the new self-levelling TLS Plus triple link front axle suspension system results in improved traction, and allows up to 10% more power to be transferred to the ground. The system automatically adjusts sensitivity and suspension rate, and synchronises with hitch sensing to compensate for power hop under heavy draft conditions. Deere says less arm movement and significantly less steering effort is required by the variable ratio steering system, which can be activated and deactivated from the tractor’s CommandCenter control console.
Other options include a new connectivity package featuring MyJobsConnect and MyJobsManager apps, which enable drivers to view and carry out tasks in real time via their mobile device. Also, John Deere claims to be the first full-line agricultural manufacturer to introduce a navigation and logistics optimisation system specially designed for farm use. The Intelligent Ag Navigation & Fleet Logistics system features all farm roads plus a fleet overview, and shows drivers the fastest and safest way to a field entrance. It can also navigate operators between an unloading point and a lead machine that moves from field to field, such as a combine or forage harvester.
