With tweaks to the line-ups of its mid-power tractors, Valtra has added more refinement and technology to its latest roll-out of fifth generation machines. Alex Heath reports.
Following the launch of the G Series last year and updates to the A Series at the start of this year, Valtra has continued to roll out its fifth generation tractors with the N and T Series the latest to be revamped.
The line-up of the six-cylinder T Series remains unchanged, with the two smallest models using an Agco Power 6.6-litre engine, while the rest of the range uses the 7.4-litre version.
Transmission options remain the same with a continuously variable transmission (CVT) or powershift to choose from. The Direct-spec with CVT is available on all models in the N and T Series except for the largest T Series model, which has the powershift, comprising four ranges with five shifts, giving 20 gears in forward and reverse. Opting for the creeper ‘box extends the choice of gears to 30.
The T235, the largest model to be fitted with the ‘Direct’ CVT now has a different standard power output than the model fitted with the powershift. This sees a standard power output of 220hp for the CVT, while the powershift version gets 235hp standard power, however, both reach 250hp on boost.
The manufacturer says all powershift transmissions now have automatic shifting from the B range, with faster changes. In addition, as soon as the tractor starts moving, the engine uses the boost engine map to develop more power.
Like the previous generation, the T175 model is available in Eco guise, meaning maximum torque increases from 780Nm on the standard model to 900Nm, while engine revs are reduced by 20 per cent, leading to fuel savings of 10 per cent, according to the manufacturer.
In the four-cylinder N Series, the bottom three models have been canned, reducing cross over with the G Series, leaving the N135, N155 and N175. These too use the same engines as before, the 4.9-litre from Agco Power. The middle model is also available as an Eco version.
Most of the notable changes that are not tucked under the tin work can be seen in the cab. In both the three-model N Series and seven-model T Series the cab has had a thorough rework, with the dash display now fixed to the A-pillar, making way for a new steering column with integrated storage. The manufacturer says adjusting the position of the steering wheel is also now easier.
The top of the new display shows default information such as the driving speed, engine speed and time. Below that, the operator can select information for controlling the tractor and implement. It also shows the radio station and smartphone information via Bluetooth.
The four spec-levels, relating to transmission choice remain, which sees the A-pillar display used to make changes to engine, hydraulic and transmission settings on HiTech and Active models. On the higher-spec Versu and Direct models, the A-pillar display and SmartTouch console divide the tasks according to suitability and the preferences of the operator.
In addition, the forward-reverse shuttle lever has been updated with return to centre function, designed to make switching between different controls such as the SmartTouch lever or the TwinTrac shuttle easier.
The manufacturer says about two thirds of its tractors now leave the factory with GPS steering, so has included all of its precision farming tools into the optional Technology Pro X bundle. This includes Valtra Guide with centimetre accuracy from Novatel or Trimble receivers, 36-point section control and variable rate control for up to five products, as well as data management transfer tools for TaskDoc Pro and Agrirouter subscription. In addition, Auto U-Pilot combines headland management sequences with guidance when turning at the end of a bout. All precision farming tools are controlled through the tractor’s terminal, with a second screen also provided in the bundle.
Tractors fitted with a front loader and SmartTouch terminal can benefit from the manufacturer’s new Precision Lift and Load app, that runs through the screen. Using sensors that measure the weight and position of the lift arms and an ECU built into the loader’s frame, operators can record weights and set lift and lower parameters. There is also a bucket shake function. Data from loading can be sent to the office for invoicing or inventory recording.
