Deere, Tier 4 engine,--Deere's First Tier 4 Machine On The Job

John Deere announced the purchase of its first Tier 4 interim machine to a New Jersey contracting firm that sought a wheel loader that would allow it to work in Brooklyn, N.Y., under current and future emissions rules. Deere said contractor J.H. Reid took delivery of the 744K wheel loader in late August and immediately put it to work on a $125-million pre-cast bridge job for the New Jersey DOT in Highlands.

“The bridge job is just a dress rehearsal,” said Eric Reid, president of J.H. Reid. “The loader is supporting us right now by working around the crusher with a bucket and carrying construction materials around the site with forks,” Reid said. The machine will be moved later this month to Brooklyn’s Hamilton Avenue waste transfer station, where New York City Best Available Control Technology emissions rules are in effect.

“Everybody knows IT4 is the future,” Reid said. “For us it’s all about the ability to work in New York City and I didn’t want to invest in something that would be obsolete in six months. Deere’s IT4 unit availability allowed us to think long-term.”

Deere said the 744K with the interim Tier 4 engine is initially targeted toward customers who need the highest emissions tier available for bid emissions specifications and green construction sites or who work in non-attainment areas. The Tier 4 interim standards take effect for engines from 175 to 750 hp in January of 2011.

The machine is powered by Deere’s PowerTech 9.0 L Tier 4 interim diesel that uses cooled exhaust gas recirculation (EGR) technology to meet emissions regulations while producing the same horsepower and torque as a 744K equipped with a Tier 3 engine.
