Chesapeake put the top loader

The top loader saved more than a
gallon of fuel per hour — and this is in
a machine that typically operates 3,000

during that time it will produce 396
tons fewer carbon dioxide emissions,
reduce particulate matter by 2,326
pounds and reduce oxides of nitrogen
by 31,584 pounds.
“Diesel engine technology has

emissions and increase fuel efficiency.
For years, diesel-operated equipment
was considered dirty and you could
easily see the puffs of black smoke
billowing from the machines. The
