a legendary powerhouse
The heart of your Valtra is the most reliable engine available.
Renowned for their durability, efficiency and extremely strong torque, AGCO Power engines have been the power source of Valtra tractors for over sixty years.
Advanced engine features ensure that Valtra tractors are reliable and comply with the latest emission standards without any increase in operating costs.
Engine models
AGCO Power 8.4 AWF – revolutionary SCR technology
The reliable 8.4 AWF AGCO POWER engine is the key to the productivity of the S Series. The engine uses the latest AGCO POWER technology to comply with the Tier 2 emissions standard. The same technology also ensures the reliability of the engine without any increase in operating costs.
AGCO Power 66 AWI and 74 AWI – the powerhouse of the T Series
The sturdy, reliable and high-torque engines on the T Series feature common-rail fuel injection. The engine idle speed is just 650 rpm, compared to around 850 rpm usually found on comparable engines. The lower engine idle speed significantly reduces fuel consumption and engine noise.
AGCO Power 44AWI and 49AWI – four-cylinder power
The common-rail engines of the larger N Series models feature precision multi-stage fuel injection at high pressure (1600/1800 bar), ensuring excellent efficiency and clean combustion. The radiator and intercooler are located next to each other to allow clean air into the engine, which in turn leads to cleaner emissions and lower fuel consumption.

EcoPower - Low-rev philosophy
Valtra EcoPower models let you choose between two different engine settings at the push of a button.
Valtra EcoPower tractors fully utilise the sturdiness and high-torque characteristics of AGCO Power engines at low revs. Compared with standard engines, the engine speed has been reduced by 400 rpm, while maintaining maximum torque in this range. This reduces fuel consumption by up to 10%.
Valtra EcoPower models offer two tractors in one.
Valtra EcoPower tractors fully utilise the sturdiness and high-torque characteristics of AGCO Power engines at low revs. Compared with standard engines, the engine speed has been reduced by 400 rpm, while maintaining maximum torque in this range. This reduces fuel consumption by up to 10%.
Benefits of low-rev engines:
- Rated speed of 1800 rpm
- Max. torque at 1100/1200 rpm
- Very high torque, even at 1000 rpm
- Wide constant torque range
- Low fuel consumption, approximately 10% lower than on engine's standard mode
- Low emissions - environmentally friendly
- Less waste oil
- Less vibrations
- Low piston speed: longer engine life
Low idle
The low idle speed means lower fuel consumption, less engine wear, and a more pleasant engine sound.
A great Valtra innovation, the low-idle feature comes as standard on common-rail models. When the driver stops the tractor and applies the handbrake, the engine speed automatically drops to just 650 rpm. In models with SCR technology, the idle speed is flexible and adjusts automatically if catalyst cooling is required after a hard run.
