SPENCER, Iowa (KTIV) -

The Spencer Ag Show often shows off some of the latest technology in the field. That's especially important for farmers.

The EPA has been pushing for higher efficiency tractors for a while now. For years, the standard has been 98 percent clean air from diesel exhaust, and by 2014, all tractors must be at 99 percent.

Workers at John Deere say their products are reaching that requirement.  Company reps are excited to be ahead of the curve.

"We're in an interim Tier 4 period," said Jeremy Thiesen of Northwest Equipment. "That means we do meet Tier 4 emissions today, but when EPA comes out with final Tier 4 recommendations and requirements, these tractors will meet spec."

Tractor companies continue to make tweaks to their GPS systems as well, but Thiesen says that technology is not nearly as advanced this year as those emission tweaks.
