Plowing Ahead Into Tier 4
AG EQUIPMENT MANUFACTURERS ON TRACK TO MEET NEW EPA EMISSIONS HURDLES; BOTH EGR AND SCR WILL BE SEEN AT INTERIM
BY DAWN M. GESKE
With all the uncertainty, fear and trepidation the EPA’s Tier 4 interim and Tier 4 final emissions standards have brought to many
segments of the off-road equipment markets, it’s almost a relief to see an area that
appears to be taking things all in stride.
And wouldn’t you know it that it’s the
one that makes the machinery for some
of the most unflappable people on earth
— farmers.
More than most, agricultural equipment manufacturers are one of the few
industries that seem to be on track and
confident of their plans to meet the
implementation of Tier 4 standards in
2011 and 2012. AGCO, Deere and most
recently Case IH and New Holland, have
all announced the Tier 4 technical paths
they’ll be following in their tractors,
sprayers and combines. And while each is
going about it in their own way, nearly all
of them went public early on and have
even sought to market their particular
solutions to customers, some as early as
last year.
Most recently, Case IH and New
Holland announced their Tier 4 interim
strategy in late February. Case IH said it
will use a two-track approach to meet
Tier 4 interim standards, using selective
catalytic reduction (SCR) systems for
medium- and heavy-duty engines greater
than 100 hp and cooled exhaust gas recir-
culation (CEGR) for light-duty engines
under 100 hp.
A number of agricultural equipment manufacturers have already announced the paths they are taking for Tier 4 interim and Tier 4 final exhaust emissions regula- tions. AGCO was one of the early adopters of selective catalytic reduction (SCR), showcasing its e3 SCR technology in its Massey Ferguson 8600 (shown here) and Challenger MT600C tractors using AGCO Sisu Power diesel engines.
