New Holland has become the first tractor maker to confirm the route it intends to take to achieve the next-but-one set of engine emissions standards, known as Stage 4 (Tier 4 Final) and due in 2014.
At a time when manufacturers are falling over themselves to outline which route they are opting for to meet the next Stage 3b (Tier 4 Interim) requirements for 2011, NH’s announcement that it will use just Selective Catalytic Reduction (SCR) brings to an end suggestions that both Exhaust Gas Recirculation (EGR) and (SCR) technology will both be required to meet the final emissions targets.
NH head of global marketing and communications Pierre Lahutte says any changes in engine technology must go hand-in-hand with improvements in efficiency for the farmer. “Selective Catalytic Reduction is a simple and good-sense solution to the emissions problem,” he explains. “Technology should be all about making farmers’ lives easier.”
In fact, to ease farmers into using AdBlue, New Holland will be providing a free 1000-litre IBC and pump with every SCR-equipped tractor bought.
What’s in a name?
Updated and expanded T7 Series
The T7000 Series has been renamed and extended, with rated power on the nine models going from 125hp to 230hp (and max boost ranging from 171hp to 269hp).
Powered by a Fiat Powertrain Technologies 6.7-litre engine fitted with SCR, the existing T7000 range (now called T7) has been joined by CVT versions of the existing short-wheelbase T6050, T6070, T6080 and T6090 semi-powershift models.
These will be badged as the T7.170, T7.185, T7.200 and T7.210 and will run from 170hp to 210hp.
They will be available with all the extras found on the larger T7s and are aimed at farmers who want something a little smaller but still with CVT and healthy power boosts.
The standard-wheelbase models will retain their transmission offerings.

Perhaps the most radical changes come in the T8 range.
New Holland admits that the existing T8000 hasn’t captured the same customers the previous 70 Series did in the ’90s, and is keen to change that with the new five-model T8 Series.
What’s immediately distinctive about the new range is the bonnet. Instead of ending abruptly it now slopes and the wheelbase has been lengthened to 3.45m. The bonnet has also been raised and sculpted to allow for Supersteer and (despite the T8 having the longest wheelbase in this segment) the turning circle has been reduced.
The T8 range now gets an FPT Cursor 9-litre engine with rated power running from 232hp to 335hp and max power from 273hp to 389hp thanks to power boost. Initial tests by NH suggest that the new SCR engine should enjoy a 17% reduction in fuel costs and servicing intervals will double.
NH also points out that for every £1 spent on the AdBlue additive required by SCR, users will save £7 in fuel. This will make the 5-10% increase in overall tractor price compared to a Stage 3a model a little easier to bear.
The T8.275, T8.300, T8.330, T8.360 and T8.390 are available with 19 x 4 50kph full powershift or with a 23 x 6 variant with creeper.
For the first time, it’s now possible to opt for a fully integrated cast front linkage, with lift capacity of close to 6.3t and 1000rpm pto. The T8 is fitted with comfort ride suspension and for better cab stability there’s Terraglide front axle suspension.

Slimmed-down T9 makes life easier on the road
Although there are some articulated-steer T9000s in the UK, until now the rest of Europe hasn’t seen much of NH’s largest offering due to homologation issues.
The new six-model T9 Series, however, has full EU approval.
There are two sub-ranges made up of two wider-framed high-hp models and four narrower models. The latter’s 1m-wide frame and that fact that they can be shod on super singles mean they can meet the 3m transport width limit.
The T9 range spans the 354hp to 608hp power band and will also use FPT Cursor engines fitted with SCR. The smaller T9.390 is fitted with a 9-litre block while the T9.450, T9.505, T9.560, T9.615 and T9.670 models all get the larger 13-litre powerplant, with the largest two also gaining a two-stage turbo.
Boosted hp now rises to between 390hp and 669hp, making the top-of-the-range T9.670 one of the largest articulated-steer tractors on the market.
As well as Ultra Command 16×2 powershift gearboxes, the T9s also get Ground Speed Management (GSM), a feature already available on the T8000 range that allows drivers to set the ideal working speed and engine rpm (a little like a CVT transmission) while the control system works out the most efficient way of working, even under heavy loads.
Up in the cab, the T9 gets the same treatment as the T8 with the addition of the SideWinder armrest with IntelliView III monitor and IntelliSteer autoguidance system. A four-point suspension is also available for the first time.
