John Deere: 7R Series tractors having new features introduced recently

John Deere introduced five new models ranging 230-310 hp with Intelligent Power Management (IPM) with new range of 7R Series tractors featuring new levels of Power, Maneuverability, and Adaptability to road transport, Combined with enhanced comfort and Improved Ergonomics. Also designed as versatile work-horses for contractors and medium-sized to large arable Farms.

The performance of its field-proven and user-friendly high-pressure common rail PowerTech Plus engine technology, John Deere has focused on keeping things simple with a single fluid approach on these latest models. The new 7R Series engines all conform to the stringent Stage 3B emission standards while applying the diesel-only principle.

The 9.0-litre PowerTech PVX engine on the three larger models – 7230R, 7260R and 7280R – features a variable geometry turbocharger, cooled exhaust gas recirculation and exhaust filters, which include a diesel oxidation catalyst and a diesel particulate filter. The two smaller models – 7200R and 7215R – are powered by 6.8-litre PowerTech PSX engine using a series turbocharger, which combines a low-pressure fixed geometry and a high-pressure variable geometry turbocharger system.

With IPM, both the 9.0-litre and 6.8-litre PowerTech PVX and PSX engines deliver an additional 30hp, providing higher power density for transport and non-stationary PTO applications. As a result, these tractors feature instant acceleration when needed most, for example when traveling uphill with a heavy load. The 544-liter fuel tank also provides many productive hours of continuous operation, with fewer stops to refuel.

Besides the engine, several other features make a significant contribution to optimum fuel economy, such as the electronically controlled viscous fan cooling system which automatically adjusts fan speed to match load changes. A ‘push fan system’ manages airflow direction to maximize the efficiency of the cooling system, with the air being pushed into the engine compartment instead of pulled in. This helps to minimize dirt intake and keeps the radiator clean.

• The transmission also plays an important role, with fuel efficiency the direct result of the driver’s skill. To match the variety of a contractor’s operations, John Deere 7R Series tractors offer a choice of four field- and road-proven transmission technologies:
  The 20 forward/20 reverse speed PowerQuad Plus automatically selects the best possible gear when shifting between ranges (Speed Matching). It features a hand declutch function that makes range shifts smoother and a SoftShift mode that automatically adjusts the engine throttle to facilitate smooth gear changes.
• With its FieldCruise and EcoShift functions, the 20 forward/20 reverse speed AutoQuad Plus transmission also features the hand declutch function
• John Deere’s newly designed CommandQuad transmission includes an Efficiency Manager that makes sure the gear and throttle work hand in hand to optimize fuel efficiency. There is a choice between a fully automatic mode, with gear and engine rpm selection depending on load, and a manual mode for targeted speed applications, which includes five ranges and four power speeds per range. In addition to the convenient CommandArm control, this transmission features 42 and 50km/hr Eco options and a left-hand reverser for easy direction changes.

For maximum fuel efficiency, the AutoPowr infinitely variable transmission has been completely redesigned. This enables the driver to smoothly shift from zero to maximum speed with no clutching at all and keeps the speed steady by automatically responding to load changes.

Along with the narrow engine bonnet design and the sleek and modern styling of the entire tractor, the new 7R Series machines feature a newly designed CommandView II cab for long working days in the field and on the road. New levels of comfort are provided by the spacious interior, the armrest controlled and roof-integrated air-conditioning system, all-round visibility both day and night with the additional glass surface area and 360-degree lighting pattern, comfortable seat options and more storage space than ever before.

For maximum operator comfort, the 7R Series tractors are optionally available with ActiveSeat suspension to compensate for up to 90 percent of the tractor’s vertical movements, as well as hydraulic cab suspension. This is a semi-active dampening system that anticipates loads and braking to maintain the overall balance of the cab, while providing the driver with an accurate feel for the tractor and ground surface.

The new right-hand CommandArm console with its integrated CommandCenter display puts all key tractor functions within easy reach of the operator. The seven-inch CommandCenter display, which is isobus compatible and includes Access Manager as standard, offers touchscreen and video options and accommodates key functions such as the canbus controlled SCVs and intelligent Total Equipment Control (iTEC), which allows the operator to automate multiple functions, simultaneously.

In addition, important AMS precision farming applications can now be operated via the CommandCenter display, including AutoTrac and Sprayer Pro. The CommandArm console features the settings for cruise control, iTEC, transmission and PTO settings, hitch functions, air-conditioning and radio controls, front-wheel-drive engagement and the light controls. John Deere 7R Series tractors equipped with PowerQuad Plus or AutoQuad Plus transmissions feature an alternative right-hand control console.

Another option is the GreenStar 2630 display, a robust touchscreen monitor equipped with USB ports and a backlit LCD. This enables the use of AutoTrac and Guidance Pro modules and provides the isobars capability, documentation, video functionality, Access Manager and a standby mode.

The newly designed structural chassis of the 7R Series tractors take advantage of the high power density to cope easily with demanding load and draft applications. For putting maximum power onto the ground, the tractors are equipped with Triple Link Suspension Plus. This features self-leveling and automatic adjustment of axle sensitivity.

Also optionally available on the new 7R Series tractors is John Deere’s exclusive fly-by-wire ActiveCommand Steering, which reduces steering effort in order to minimize operator fatigue and improve driving comfort and control. This fully electronic steering control system automatically adjusts the road wheel angle based on the lateral acceleration of the tractor. This system improves control when cornering at transport speeds, as well as the tractor’s ability to hold a straight line. Furthermore, the system’s Variable Ratio Steering module reduces lock-to-lock turning in the field, for quicker headland turns. Compared to a conventional steering system, ActiveCommand Steering enables a 75 percent reduction in typical hand movement.

    John Deere’s new 7R Series tractors provide instant access to all critical functions and parts for fast and easy daily servicing. John Deere dealers are able to keep the tractors running in optimum condition, for example using the Service Advisor diagnostics system, which can also be remotely operated for fast and reliable service inspections.
