New Holland Agriculture is fully committed to providing ingenious solutions that make farming more efficient whilst respecting the environment. The Tier 4 solution that has been chosen is perfectly in line with this philosophy. Moreover, the brand does not simply consider this as a legal requirement, but as a fundamental role of agricultural machinery manufacturers in order to safeguard the farming environment for future generations, here in New Zealand.

The Clean Energy Leader

New Holland’s Clean Energy Leader position is based on fundamental elements for environmental respect including biodiesel, Tier 4, the NH2™ hydrogen tractor and the Energy Independent Farm concept.

New Holland is internationally recognised as the pioneer in the use of renewable fuels, and was the first manufacturer to offer biodiesel compatibility for its products back in 2006. During the last five years, further research has been conducted into biodiesel’s agricultural applications, and currently, 85% of the entire New Holland product range can run on 100% biodiesel.

The revolutionary award-winning NH2™ hydrogen tractor within the Energy Independent Farm Concept sees farmers enjoying complete fuel autonomy, and providing for all their own fuel needs. New Holland is currently in the process of establishing the very first pilot Energy Independent farm close to the brand’s headquarters in Turin, Italy.

Together with our engine development partner, Fiat Powertrain Technologies, we are currently introducing a range of highly fuel efficient, productive Tier 4A compliant engines that offer lower operating costs.

New Holland boast the widest Tier 4A offering of any agricultural manufacturer in terms of absolute models, with 20 tractor and six combine harvester models. The brand’s Tier 4A solution offers its customers tomorrow’s technology today, as New Holland will also use SCR technology to meet the ever more stringent Tier 4B emissions regulations which will be introduced in 2014. This is confirmed by all of the industry’s leading engine experts.

Tier 4A: maximising performance, minimising emissions

Today’s engines are already significantly less polluting than their predecessors. Current Tier 3 engines emit 60% less particulate matter (PM) and nitrogen oxides (NOx) than their Tier 1 counterparts. With the introduction of the stringent Tier 4A emissions regulations, PM will be reduced by a further 90% and NOx by 50% over Tier 3 levels. In real terms, this means that a farmer can work almost 100 days with a Tier 4A machine, and produce the same level of emissions as just one Tier 1 machine would have in a single day.

The Tier 4A regulations (also referred to as Tier 4 interim) came into force for products with engines over 174hp (130kW) in January 2011, and New Holland will use selective catalytic reduction (SCR) technology for all machines producing over 100hp.

The advanced SCR engine solution was developed in partnership with Fiat Powertrain Technologies, the leader in environmentally friendly engines, who have already produced over 150,000 proven SCR engines.

The Tier 4A compliant SCR engines have significant environmental and productivity advantages. "SCR technology improves engine breathability, as the powerplants ‘breathe’ clean fresh air instead of hot, dirty, recirculated smog to ensure optimal combustion conditions. This results in increased maximum power and higher torque for improved machine performance, ” stated Pierre Lahutte, Head of Global and European Communications and Marketing. He continued, "Moreover, the SCR technology uses an after treatment system located in the exhaust to neutralise the harmful emissions, so the engine is 100% dedicated to generating power. This means that farmers and contractors have more performance enhancing power available to improve the efficiency of their businesses.”

One of the principal benefits of SCR technology is that it does not place any additional demands on the cooling package, which means that no power is diverted to cool the exhaust gas. Therefore, the engine’s power is only used for the machines principal ‘working’ functions, improving productivity.

Thanks to the cutting-edge SCR system, used on high horsepower machines over 100hp, engines will benefit from significantly improved fuel consumption which means a reduced consumption of finite fossil fuels. Early tests indicate that New Holland’s solution will offer class-leading fuel consumption in the T7 segment, in which it has already established itself as a fuel efficiency leader. Moreover, significantly improved service intervals, up to 100% in some cases, combined with the fact that no special low-ash lubricants are required, means the brand’s and our customers, environmental profile will be significantly improved.

As a direct result of using SCR technology to conform to Tier 4A standards, these machines will benefit from a significantly increased Engine Horsepower Management (EPM) band, up to 71hp on some models in the T9 range. The brand’s renowned EPM technology continuously adjusts engine output to working conditions by an intelligent sensing of the PTO, hydraulic and transmission loads. This ensures the optimum generation of power by the engine, which also always runs at the most efficient settings. This guarantees both optimised performance and optimal fuel consumption. This means that customers have the most efficient power in reserve to operate even the biggest implements in the toughest conditions.

The SCR system requires the use of AdBlue, a non-toxic water and urea solution, to neutralise the noxious nitrogen oxides found in the exhaust emissions and to turn them into harmless water and nitrogen, both of which occur naturally in the environment. AdBlue contributes to significant savings, even when the initial purchase price is taken into account.

All New Holland authorised dealers will stock all products required to ensure conformity with new Tier 4A regulations, including AdBlue, in containers of varying sizes in order to suit individual farmers needs.

These saving courtesy of AdBlue also contribute to overall machine cost savings of up to 17% on selected models, which our customers will be able to enjoy at Tier 4A thanks to reduced fuel consumption, increased service intervals, on some models service intervals have doubled, and longer engine life.

By opting for SCR technology, New Holland customers have invested in an emissions solution that will pay back. Moreover, New Holland is committed to providing its customers with tomorrow’s technology today, and SCR technology is the perfect example of this philosophy.

New Holland will use SCR technology to reach the even more stringent Tier 4B emissions norms which will be phased in from 2014 onwards for the entire product range. This has significant benefits for our customers, by already using SCR technology in 2011, our research investments will be focused on developing the next generation of agricultural machinery that will redefine the efficiency, comfort and performance that farmers demand.

Evolution in New Holland’s naming strategy for high horsepower tractors

New Holland’s SCR Tier 4A solution has significantly improved high horsepower tractors performance, as such, in order to highlight these benefits, the brand is currently introducing an evolution in the numbering of these models. "The numbering evolution fully leverages on the benefits of the Tier 4A SCR solution, and focuses on its technological advantages. There have been significant improvements in power, performance and fuel economy, and operators will, in particular, benefit from a significantly improved Engine Power Management band, ” stated Pierre Lahutte.

He continued, "This evolution means that farmers will immediately see the maximum performance of their tractor on the bonnet, and can work safe in the knowledge that it will be able to tackle even the most demanding applications with no loss in productivity or efficiency.” This is also being rolled out in conjunction with a distinctive new graphic element.

New Holland’s numbering strategy uses two key elements, related to tractor range category and maximum engine power management horsepower.

The first letter, T, and following digit, either 7, 8 or 9, denote the tractor’s range category: the higher the number, the larger the tractor.

The second three digits represent the maximum engine power management horsepower.

Model name
Maximum Engine Power Management Horsepower

The new graphic image on the bonnet underlines the new numbering approach, as the maximum engine horsepower management figure will be included along with New Holland’s trademark silver leaf and yellow swoosh.

This evolution will be introduced when new products are launched, pre-existing tractor ranges will retain their current names and numbers.
