AGCO’s Tractors Pack New Power

The new row crop tractors spanning the AGCO DT Series, Challenger MT600B Series and Massey Ferguson 8600 Series are the first ag workhorses to be outfitted with engines using selective catalytic reduction (SCR) technology. The tractors are outfitted with AGCO Sisu Power engines that use SCR technology (over-the-road trucks use similar systems). The technolo­gy makes the tractors Tier 3 compliant and poises the machines to be Interim Tier 4 compliant in 2011.
 
AGCO has dubbed the engine technology as e3–energy, economy and ecology.
 
"SCR provides emissions compli­ance while letting the engines be engines," explains Jason Hoult, AGCO product marketing manager. "SCR gets up to 15% better fuel economy over exhaust gas recircula­tion (EGR) technology. Even with the additional expense of diesel exhaust fluid (DEF), which costs about the same as diesel fuel, you're still getting 12% savings total."
 
Engines that use SCR technology treat emissions after the combustion process is finished. In a catalytic converter the nitrogen oxide is mixed with the DEF and nitrogen and water are the only final emissions.
 
The DEF used in the SCR engines will be a 32% aqueous ammonia solution. It's expected that the DEF tank will need to be refilled at every other diesel tank fill up. AGCO dealers will stock DEF in 2.5-gal. jugs, and it should also be available through retailers serving the on-road truck market as well. 

AGCO CEO Martin Richenhagen gives his point of view:
