John Deere: Full 6R line-up revealed

Following the introduction of the company’s new 6R Series large-frame tractors in June 2011, John Deere has now unveiled the complete 6R tractor line-up.
Nine models from 105-210hp – 125-240hp with Intelligent Power Management (IPM) – are now available. Featuring the new John Deere tractor family styling, all 6R models offer new levels of power, performance and operator comfort, including improved suspension and cab visibility, more powerful hydraulics and increased lift capacities.
Models from the 6105R to 6130R are equipped with a Stage IIIB 4.5-litre four-cylinder PowerTech PVX engine rated from 105 to 130hp. IPM generates an additional 20hp for road and PTO applications. The 6130R model is powered by the same four-cylinder engine mounted on a six-cylinder frame. With its longer wheelbase, this tractor is designed for better performance, and features: higher lift capacity; higher fuel tank capacity; improved loader performance; and higher stability and driveability during transport and in hilly conditions.
The 6140R to the 6210R are equipped with a Stage IIIB 6.8-litre six-cylinder PowerTech PVX engine rated from 140-210hp, or maximum 160-240hp with IPM. John Deere’s engines use field-proven technology to meet the latest emission standards, based on exhaust gas recirculation and a variable geometry turbocharger, with the addition of an exhaust filter that contains a diesel oxidation catalyst and a diesel particulate filter.
Based on John Deere’s established full-frame design, these new tractors also have a longer wheelbase of 2580mm (6105R to 6125R), 2765mm (6130R to 6150R) or 2800mm (6170R to 6210R). These frames provide improved stability for loader applications. In addition, a higher permissible weight and payload allow bigger and heavier implements to be carried.
The large frame models offer the same wheelbase as the previous John Deere 7810 tractor, and can be fitted with larger Group 48 tyres with a maximum diameter of 205cm, which is unique to the industry in this tractor category. Similarly, the 6140R and 6150R can be equipped with group 47 tyres with up to 195cm diameter, which is also a unique industry feature. A 2m tread setting is available for either fixed or adjustable wheels, with the option of a flanged or rack and pinion axle on the large frame models.
An integrated front hitch with a lift capacity of 4,000kg and a new front PTO are also available ex-factory for the first time on 6R Series tractors. The front hitch is fully compatible with the new John Deere H-Series front loaders, which have been designed to provide maximum visibility and to match the new tyre size and tractor chassis dimensions.
With the newly designed 24-speed DirectDrive transmission, John Deere has introduced a completely new technology to the agricultural machinery industry. The double clutch technology is already established in the prestige car industry, and is now available in a tractor for the first time. It combines the handling comfort of an infinitely variable shift (IVT) transmission with the power efficiency of a mechanical transmission, and has been designed to provide outstanding efficiency for ploughing and towing, PTO work and road transport.
Key customer benefits are enhanced power efficiency and improved fuel efficiency, resulting in savings of up to 10g/kWh compared to an IVT transmission. Additionally, just like in Formula 1 racing cars, electromagnetic actuators enable fast changes between speeds and ranges.
The operator can choose between a manual mode to take command of forward and reverse speed changes via the control lever, or an automatic mode. In this mode, speeds within a range are automatically changed as well as the A, B and C ranges. Depending on the actual load, the Efficiency Manager function optimises the tractor’s efficiency by automatically matching the appropriate speed and engine rpm. The 40 or 50km/hr top speeds are achieved with significantly reduced engine rpm.
The AutoPowr continuously variable transmission, as well as AutoQuad Plus and PowrQuad Plus with SoftShift for smoother gear changes under load, complete the range of transmission options. The 40km/hr AutoQuad Plus EcoShift transmission can produce lower engine rpm at high transport speeds, to maximise operator comfort and reduce fuel consumption. With the new AutoPowr drive pedal mode, operators can choose between three different settings depending on the application or their driving strategy.
The new 6R ComfortView cab has more than 20 per cent more space and a similar increase in visibility. It offers a completely new level of operator comfort, with features such as the seven-inch full-colour GreenStar 3 CommandCenter display with optional touch screen and video capability, integrated climate and radio controls, Bluetooth connectivity with SIM card access and an optional panorama roof. The display is fully compatible with ISOBUS and tractor-implement automation applications. Furthermore, the GS3 CommandCenter offers complete AutoTrac automatic steering capability.
Further options include the new HCS Plus hydraulic cab suspension and TLS Plus triple link suspension for the front axle, to provide optimum traction and operator comfort. TLS Plus transfers up to seven per cent more power onto the ground, and features +/-50mm of suspension travel as well as automatic adjustment of axle sensitivity and the suspension rate.
The new versatile lighting system on 6R Series tractors delivers 185 per cent more light output compared to previous models. It includes up to 10 cab lights integrated into the front, rear and sides of the roof line to provide 320 degree lighting, plus six adjustable belt-line and rear fender field lights. An additional six field, spot and road lights on the grille complete the lighting possibilities, as well as eight optional Xenon lights that are all controlled from the CommandCenter display.
