Valtra's T Series with SCR technology uses 5-10 per cent less fuel.
The largest Valtra T Series models have undergone a
transformation to meet planned engine emission regulations. In addition to fuel saving SCR technology, however, the new
models offer a vast number of other innovations that help and enhance
operation.
At the core of the T183 and T203 Direct models and the T183 and T213
Versu models is the 7.4-litre Agco Sisu Power SCR engine. These SCR
engines consume about 5-10 per cent less fuel than a corresponding
engine without SCR technology. Additionally, SCR technology reduces the
motor's cooling requirements, while reduced deposits keep lubricants
cleaner. The SCR engine's fine particle emission is now only three per cent of
emissions before regulations were introduced. NOx emissions are also
down; to only 20 per cent of pre-regulation levels. Thus SCR technology
saves fuel and reduces environmental pollution.
Valtra has several years of experience with the SCR technique. The
Valtra S series, introduced in 2008, was the first agricultural tractor
to utilise SCR technology. Adding AdBlue urea solution by injecting it
into a catalytic converter has been used in road vehicles, particularly
heavy trucks, for some years as a way of controlling emissions. The SCR
system requires little operator input; electronics take care of the
equipment's functions with the operator only needing to fill the AdBlue
tank the same way as he or she would fill a fuel tank or windscreen
washer liquid tank. Engines at emission level Stage 3B consume AdBlue at
about 3-5 per cent of total fuel consumption.
There is slightly more power and decidedly more torque in the new
engines, and the nominal speed has been lowered to 2,100rpm.
Additionally, Sigma Power and Transport Boost power have been increased.
The T213 Versu has 15hp more than previous models. The torque and power graphs, as well as the
teamwork between the motor and transmission of both the Versu and
Direct models has been renewed. With new software, the tractors equipped
with stepless or powershift transmissions provide performances that meet
all operational requirements.

There are many more new features in T3 series tractors than engine
technology. The Valtra ARM armrest now incorporates a colour screen
with separate settings for day and night use. The joystick on the arm
support can be used for front hydraulics, rear hydraulics, or both. The
settings of both headland management and cruise control can now be
modified more precisely; even when stationary. Power take-off and
four-wheel-drive rocker switches are now incorporated in the new armrest.
The new T series is available with factory-installed automated
steering readiness, or with System 150, a comprehensive autopilot based
on satellite radio determination capable of steering the tractor with
great precision to within a very few centimetres.
The Agcommand tracking
system is also available as a factory installed option. this is
based on satellite radio determination, and can be used to track the
location of the tractor, the work in hand, work efficiency and the
service demand from any computer linked to the internet.
