New Holland has upgraded the T4 PowerStar series of smaller tractors, which is the first tractor range of this size in Europe to feature PM Cat (Particulate Matter Catalyst) technology for Tier 4B compliance. The tractors were shown for the first time in Europe at Cereals 2014 in England last week.

The three-model range also benefits from Common Rail technology for lower fuel consumption and improved operating productivity and efficiency. New Holland is claiming up to a 13% fuel saving with these tractors compared with the models that they replace. The tractors have a power-to-weight ratio of 30.4 kg/hp. The lift capacity on all three models is 2,760kg.

The T4 PowerStar series is powered by a 3.4 litre, FPT Industrial, common rail engine with PM Cat technology for Tier 4B compliance. The PM Cat is located in the exhaust system downstream from the diesel oxidisation catalyst. When particulate matter contained in the exhaust gas passes through, it is burned off.

New Holland claims that this filter never blocks due to the high flow of exhaust gas, and does not require regeneration.

The company claims that this system requires no additional efforts from the operator to activate the cleansing process and is absolutely maintenance free.

FPT Industrial has produced 500,000 engines with PM Cat technology and the system has been designed to last the life of the product.

The New Holland T4.55-65-75 PowerStar series with the common rail fuel system claims to give an enhanced engine response when the engine is placed under load.

The reason for the 13% claim in fuel savings is that only the exact amount of fuel is injected to meet the engine loading, New Holland claims.

The company says the flat engine curve between 1900rpm and 2100rpm maintains maximum power over a larger working range for improved operational flexibility. It claims that this is especially noticeable when working with power-hungry implements such as forage wagons.

The T4 PowerStar’s service intervals have been further extended by 20% to 600 hours, resulting in lower downtime and operating costs.
