New construction and farm equipment engines from John Deere Power Systems were recently certified by two regulatory bodies.

Both the U.S. Environmental Protection Agency and the European Union gave their stamp of approval regarding Interim Tier 4 and Stage III B regulations on the company's PowerTech PSX and PVX 6.8L engines. The latter machines were given the green light for 174 horsepower and above.

Doug Laudick, product planning manager for JDPS, said users of the 6.8L models have provided positive feedback through the testing process and that certification validates the company's validation process.

"And, we remain committed to ensuring our engines withstand the extreme vibration, temperatures and duty cycles found in those applications," Laudick said.

While governments at the federal level are making efforts to curb diesel emissions, state and city governments are doing the same. In fact, some construction projects will require companies meet these standards to be granted work contracts.

However, some operators may not be able to afford newer pieces of equipment, which may mean they have to buy special filters for their machines. This could come with additional costs associated with retrofitting devices.
