Valtra has just launched its fourth generation N Series. The four-cylinder N Series now boasts many of the same features which proved so popular with buyers of its big brother, the six-cylinder T Series.
The idea is that the successful features of the T Series are being introduced to a smaller, more compact class of tractors such as the N Series will certainly be of interest to Irish buyers.
The N Series boasts an AGCO Power Tier IV compliant engine producing up to 185 horsepower and 730 Nm of torque. Valtra has been a pioneer in manufacturing high-output four-cylinder tractors.
Since 1969 when the Valmet 1100 model was introduced with the world's first turbocharged four-cylinder tractor engine generating an impressive 115 horsepower, Valtra has produced some of the most powerful four-cylinder tractors in the world through its M and N Series tractors.
All round visibility
The new cab on the fourth generation N Series is similar to that on the new T Series. The cab offers excellent visibility in all directions (with up to 6.5 square metres of glass) and it is extremely quiet (<70 db).
The cab can be comprehensively specified, for example with a high-end stereo with integrated woofer, a front windscreen wiper that covers 270 degrees, heated front and rear screens, and a TwinTrac reverse drive system.
Customers who do a lot of front loader work may specify an extra window in the roof that offers an unobstructed view to the implement when the loader is in its highest position.
The N Series is available with either one or two doors. A new option is the SkyView forest cab, which offers enhanced visibility to the rear and upwards thanks to a large polycarbonate window with wiper.
The standard size of the fuel tank is 250 litres, the optional size is 300 litres, and the capacity of the urea tank is 45 litres.
The fourth generation T Series began the revolution in power shift transmissions by making it possible for the first time to operate the power shift like a stepless transmission.
The power shift tractors also have a hill-hold feature, a patented hydraulics assistant and Automatic Slip Regulator (ASR) to ensure the optimal ease of use, productivity and efficiency for demanding tasks. Valtra claims ASR represents a completely new innovation in the tractor industry.
As in passenger cars, the traction control system limits engine power if the sensors and tyre speed exceed a set level.
The idea behind ASR is to help the driver maintain the best pulling ratio and fuel efficiency while avoiding damage to the ground.
The transmission options on the new N Series are more comprehensive than ever before: HiTech, Active, Versu and Direct. The first three are five-step power shift transmissions, while the Direct transmission is stepless.
The hydraulics on HiTech and Active models are controlled mechanically, while those on Versu and Direct models are controlled electronically. Up to seven hydraulic blocks are available, in addition, four can be in the front.
AGCO Power has implemented a selective catalytic reduction (SCR) only strategy since 2009, systematically developing SCR solutions.
The N104, N114 and N124 models are powered by four-cylinder 4.4-itre AGCO Power engines, while the N134, N154 and N174 models have 4.9-litre engines.
The SCR system takes care of exhaust emissions without the need for a diesel particulate filter or exhaust gas recirculation system.
The fourth generation N Series has a turning radius of just 4.5 metres and a wheelbase of 2665 millimetres, making it very agile for front loader work but also stable on the road.
Ground clearance is an impressive 55 centimetres, making the N Series suitable for forest work, snow ploughing, harvesting and field work.
The service interval is 600 hours, saving money and allowing uninterrupted work during the peak season.
Scheduled maintenance can also be performed faster than before.
For daily inspections the driver has to make just five checks, which can be done very easily.
The N Series is tailor-made according to the customer's preferences at the Valtra factory in Suolahti, Finland.
Hundreds of features and options are available, creating millions of potential combinations.
For example, the specification list includes seven different colour options, a pivoting front linkage and an auxiliary heater.
