Machinery that complies with emission standards was featured in March at an Iowa farm show, according to wcfcourier.com.
The University of Northern Iowa in Cedar Falls hosted the 24th annual Hawkeye Farm Show during the first weekend of the month. Though some equipment on display costs as much as 15 percent more for engine improvements to meet Tier 4 standards, many attendees were on hand to do more than window shop since the farm economy is booming.
But one farmer, before committing to a purchase, said he'll monitor prices and engine efficiency. He said he and his colleagues know of Tier 4 regulations.
"I'm going to have a wait-and-see attitude," Paul Leerhoff told the publication. "Emissions are not a huge issue for us. (But) technology and fuel is important."
Many examples of John Deere farm equipment are equipped with systems that generate less emissions since excess amounts of exhaust are captured, cooled and redirected.
"A year ago I thought (Tier 4) would be a big issue, but now it's not even a consideration," said Brent Judisch, Waverly Implement salesman. "We started to be more green since 1995. It's a 20-year process."
