Completely new features for 4-cylinder tractors – up to 185hp / 730 Nm
The Valtra N Series has entered its fourth generation. The four-cylinder N Series now boasts many of the same features appreciated by customers as found on its big brother, the six-cylinder T Series, which reached its fourth generation a year ago. The new T Series has proven to be a success, and now the same successful concept is being introduced in the smaller class of tractors that now has even more compact dimensions than before.
The new N Series boasts an AGCO Power – Tier4 Final 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.
New cab offers optimal comfort in all working conditions
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. Other forest specifications include narrow mudguards and a 160-litre steel fuel tank. 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.
Powershift revolution continues
The fourth generation T Series began the revolution in powershift transmissions by making it possible for the first time to operate the powershift like a stepless transmission. The powershift 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.
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.
A suitable transmission for all tasks
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 powershift transmissions, while the Direct transmission is stepless. The Active, Versu and Direct transmissions also feature load-sensing hydraulics, and customers can select between outputs of 115, 160 or 200 litres per minute. The HiTech transmission comes with a gear pump producing 73 or 90 litres per minute. 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. The N104, N114 and N124 are available as HiTech models, while the N134, N154 and N174 are available as HiTech, Active, Versu and Direct models. The N104, N114 and N124 can be specified with HiTrol turbine clutch.
The PTO has three speeds, and ground speed PTO is available as preferred by forest and transport contractors.
AGCO Power Tier4 engine – a pioneer in SCR Only technology since 2009
AGCO Power has implemented an SCR Only strategy since 2009, systematically developing SCR solutions. The result is the most fuel efficient and responsive engine on the market. 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 SCR Only system reduces fuel consumption and extends engine life.
Valtra’s Sigma Power technology provides ten extra horsepower when the PTO is under sufficient load. In the N174 Simga+ model the system provides 20 extra horsepower. All models also feature the transport boost function, which provides extra power when driving on the road.
The N114 and N154 represent Valtra’s traditional EcoPower models in which the driver can select between eco and normal mode. In eco mode the engine speed is reduced by 10 to 20 percent, and maximum torque is achieved at lower rpm. Eco mode reduces fuel consumption by up to 10 percent compared to the normal driving mode.
Easy to use and maintain
The fourth generation N Series has a turning radius of just 4.5 metres and a wheelbase of 2665 millimetres, making it supremely agile for front loader work but also extremely 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.
Many new options
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. Naturally, the new N Series can be specified also with remote telemetry and the AutoGuide 3000 steering assist system. If all of these features and options are still not enough, the customer’s tractor can be further customised in the Valtra Unlimited studio, where even the sky is not the limit.
