New Holland’s flagship T8 Series tractor range has been further enriched with the introduction of the renowned AutoCommand continuously variable transmission. The new range-topping T8.420 develops an impressive maximum 419 hp with engine power management making it the world’s most powerful CVT tractor.
The six model T8 Series line-up, with outputs ranging from 273 hp to 419 hp, is powered by efficient ECOBlue SCR Cursor 9 engines, developed in collaboration with FPT Industrial, and delivering Tier 4 Interim emissions compliance.
“The T8 AutoCommand will become the tractor of choice and the ultimate working tool for large scale cash crop farmers, hay and forage contractors, together with large dairies and transport intensive operations,” states Luca Mainardi, Head of Tractor and PLM Product Management. “With a longer wheelbase and even more power on tap, the T8 AutoCommand is set to improve its already impressive all-round performance. Furthermore, it perfectly complements the existing full powershift model range.”
AutoCommand transmission for maximum efficiency
New Holland has tailored its AutoCommand transmission for the T8 range to perfectly match its dimensions and usage profile. The AutoCommand transmission uses intuitive force-based logic and is controlled via the ergonomic CommandGrip handle, identical to that found on T7 AutoCommand models. The four modes of operation known from T7 AutoCommand -- Auto, Cruise, PTO and Manual -- provide the same flexibility to optimize task or fuel efficiency. All transmission functions are grouped in one place for a smooth seamless application of power: if working in Auto mode, the operator simply selects the desired working speed, and the AutoCommand will adjust the engine speed and transmission settings to achieve the most efficient performance.
The T8 AutoCommand features four points of optimized efficiency where the transmission drives through a full mechanical connection. These points have been engineered by design to correspond to the most frequently used operating speeds. Whether you need a speed for planting, tillage, baling or road transport, T8 AutoCommand can deliver. Available in 25 mph ECO and 31 mph options, customers can reach top speeds at lower engine speeds if loads permit (1,400 rpm and 1,725 rpm respectively), ideal for businesses that undertake extensive transport activities.
Even more stable. Even more traction.
All T8 AutoCommand models benefit from an increased wheelbase, improving stability and traction: units fitted with standard-duty rear axle by 2 inches, while T8.390 and T8.420, when fitted with the new heavy-duty 5 in. bar axle, by 4 inches versus equivalent current models. The wheelbase of 11 ft. 6 in. in total, is a full 14% longer than the nearest competitor, yet T8 tractors still deliver staggering turn performance.
All T8 AutoCommand models can be delivered with Group 49 rear tires. If air volume and flotation is the requirement, 900/60R42 tires are offered; for row crop use, 480/95R50 tires provide a longer footprint to generate greater traction. These are the largest rear tires currently available in the market for high powered tractors.
Extensive ballasting options for enhanced in-field productivity
Ballasting flexibility has been further increased with the release of new wheel weights to enhance overall productivity by maintaining traction in even the most difficult conditions. Single-wheel T8 tractors can have up to 5,500 lbs. added to the rear axle, and when dual wheels are used, the rear axle ballast loading can now be increase to 9,000 lbs. This loading allows the T8.420 to fully utilize the available power, even at slow speeds.
The new 419 hp T8.420 and AutoCommand transmission are scheduled for full production in July 2013.
