Introducing new levels of productivity and operator comfort for large arable farmers and contractors, John Deere has announced its new 8R and 8RT Series tractors, which include the industry’s first ever tracked models with an infinitely variable transmission. Following the company’s new numbering strategy, these tractors replace the current 8030 Series models, and line up as follows:

Key features include:

·        increases of 15 to 20hp compared to the previous 8030 Series models, with up to 380hp on the largest models for increased productivity while maintaining optimum fuel economy;

·        a new, spacious CommandView II cab for maximum operator comfort and performance;

·        a choice of 16/5 automatic PowerShift or AutoPowr infinitely variable transmissions on all models except the top of the range 8345R and 8345RT, which are AutoPowr only – both transmissions allow a 24 per cent increase in transport speed to 42kph;

·        all-new 8RT track tractors, including a new AirCushion suspension system for a smoother, faster ride both on the road and in the field, plus availability of the established AutoPowr transmission for the first time on tracked machines.

The new CommandView II cab has been significantly enhanced compared to its predecessor. The right-hand console has been removed entirely, and the cab now features seven per cent more glass and 10 per cent more interior volume, four times the storage space and 25 per cent extra seat swivel. Most functions that were formerly located on the right-hand console have been relocated to the redesigned CommandARM, including a new 7in CommandCentre colour display.

The 8R Series wheeled tractors are equipped with front axle independent link suspension (ILS), with Active Seat as the secondary suspension system. This isolates the operator from 90 per cent of the vertical movements in typical tractor applications, meaning less operator fatigue and more comfort at faster field speeds.

All 8R and 8RT Series tractors for EU markets are equipped with a 9 litre four-valve common rail John Deere PowerTech Plus diesel engine, which incorporates variable geometry turbocharger (VGT) and exhaust gas recirculation (EGR) technology to meet Tier III emission requirements. The engine is also equipped with Intelligent Power Management (IPM), which provides up to 35 additional hp in non-stationary pto and transport applications, and up to 47 additional hp with maximum IPM at 1900rpm.

The AutoPowr transmission exclusively enables John Deere tracked tractor owners to precisely vary their speed and even operate the tractors with creeper speeds as low as 50m/hr. In addition, fuel tank capacity on the tracked models has been increased by more than 50 per cent, to 758 litres.

The new undercarriage suspension with AirCushion system on 8RT Series tractors significantly improves overall ride quality and operator comfort. These models have one air cushion bag and one track tension accumulator per track, compared with two on the current 9030T Series.

Wheelbase of the tracked tractors has been lengthened by 254mm (10in), providing a longer footprint to deliver the higher horsepower to the ground. In addition, this increased length helps to distribute the weight better and provide a smoother ride. The new tracks are available in widths of 635 or 762mm (25 or 30in).

Both 8R and 8RT Series tractors now feature intelligent total equipment control (iTEC), which replaces the previous implement management system (IMS). This integrated tractor and implement control system is easy to set up and operate, relieving the operator’s workload and saving time during headland turns.

In addition, a range of AMS guidance solutions are available across the range. All models will come AutoTrac-ready as standard, while optional upgrades include iTEC Pro for automatic headland turns and iGuide passive implement control for more accurate work in hilly conditions.
