New 6R Series tractors offer more power, comfort and security

With more than 550,000 units produced by the Mannheim factory since 1992, John Deere’s 6000 Series is Europe’s most successful tractor range. The newly styled 6R Series models for 2012 now introduce new levels of power, performance and operator comfort, including improved suspension, unprecedented cab visibility, more powerful hydraulics and increased lift capacities. For added security, 6R tractors are also fitted as standard with CESAR Datatag and immobiliser systems, with a unique transponder based key.

Three large frame models are initially available, the 6170R, 6190R and 6210R, equipped with a Stage IIIB 6.8-litre six-cylinder PowerTech PVX engine rated from 170 to 210hp, or a maximum of 200 to 240hp with Intelligent Power Management (according to 97/68EC). This makes the top of the range 6210R the biggest tractor ever built at Mannheim, and the first model to be produced by the factory with over 200 rated hp.

This is more power than the existing 7830 tractor from the 7030 Series, yet it weighs 1.5 tonnes less, at under 8 tonnes, which provides the ultimate power-to-weight ratio for this category of tractor. Based on John Deere’s established full-frame design, these new models also have a longer wheelbase of 2.8m and can be fitted with larger Group 48 tyres with a maximum diameter of 205cm, the same size as 8R Series tractors.

This will help to deliver extra traction by delivering all the power to the ground, while at the same time minimising soil compaction, thus increasing overall productivity and performance. The heavy-duty rear axle also provides fast and stepless tread setting changes. A 2.25m tread setting is available for either fixed or adjustable wheels, with the option of a flanged or rack & pinion axle for extra versatility.

An optional front pto and an integrated front hitch with a lift capacity of 4000kg are also available ex-factory for the first time on 6R Series tractors, while maximum lift capacity of the rear hitch is 9550kg on the 6210R. The front hitch is fully compatible with the new John Deere H Series front loaders, which have been developed to provide maximum visibility and to match the new tyre size and tractor chassis dimensions. The loaders are available in non self-levelling (NSL), mechanical self-levelling (MSL) and hydraulic self-levelling (HSL) versions, with a wide range of attachments.

The loader boom suspension can be switched on and off from the cab via a button on the new mechanical joystick control lever, which can operate up to three independent hydraulic functions simultaneously. The new loaders also feature the established MemoSystem for automatic positioning of the bucket or implement.

John Deere’s fuel efficient diesel-only engine uses field proven technology to meet the latest emissions standards, based on exhaust gas recirculation (EGR) and a variable geometry turbocharger (VGT), with the addition of an exhaust filter that contains a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF), as widely used in the construction and automotive industries. An innovative distributed cooling system further improves engine performance.

Transmission options include the established AutoPowr continuously variable transmission, as well as AutoQuad Plus and PowerQuadPlus with SoftShift for smoother gear changes under load. The 40kph 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, the operator can choose between three different settings depending on the application or their driving style. Once the desired engine rpm is set using the hand throttle, forward speed can be independently adjusted using the drive pedal.

The new 6R ComfortView cab has over 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 7in full-colour GreenStar 3 CommandCenter display with optional touch screen and video capability, adjustable air suspended seat, integrated climate and radio controls, Bluetooth connectivity and an optional panorama roof. The display is fully compatible with ISOBUS and tractor-implement automation (TIA) applications.

The right-hand CommandArm console helps to maximise productivity with hot keys for field cruise control, the iTEC automatic implement control system, transmission and pto settings, all hitch functions and MFWD controls. It also accommodates the radio, air conditioning and light controls. The optional all-in-one GreenStar 2630 display has a robust touch screen with backlit LCD, This enables powerful applications such as Guidance Pro modules, advanced ISOBUS capability, documentation and video monitoring of implements.

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 field performance. TLS Plus transfers up to 7 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 360 degree visibility, plus six adjustable belt-line and rear fender field lights, and six field, spot and road lights on the bonnet grille. Eight optional Xenon lights are also available, and all the lights are controlled from the CommandCenter display.
