John Deere:
John Deere announces results of recently completed Nebraska Tractor Test Lab evaluations of its 8320R tractor.
The tests, which were conducted in October 2009, show the 320 rated engine horsepower John Deere 8320R provides greater fuel efficiency and higher p.t.o. and drawbar horsepower ratings when compared to similar sized competitive tractor models….
Chad Hogan, division marketing manager for 8 Series Tractors, says the Nebraska Tractor Test results prove that the 8320R tractor provides up to 26 percent greater fuel efficiency over other competitive tractors of similar size in the 75 percent of pull at maximum power category.

Late August hail storm catches farmers in prime harvest mode, damaging half million acres of crops in Alberta.
“Contrary to some information that’s out there, in apples-to-apples Nebraska Tractor Test evaluations, the 8320R provides the greatest fuel efficiency in its advertised power class in test categories that best represent typical on-farm fieldwork – not stationary p.t.o. applications,” Hogan says.
“This represents a fuel savings of as much as 3.5 gallons per hour in the 75 percent of pull at maximum power test, or a savings of up to 2,450 gallons of diesel fuel annually, based on operating a tractor 700 hours per year.”
Agco:
Test results recently released by the University of Nebraska Tractor Test Laboratory confirm the new line of 205 to 275 p.t.o. horsepower row crop tractors from Agco introduced in 2009 offers the greatest fuel efficiency among tractors of this category on the market….
“The fuel efficiency test results validated and released by the Nebraska lab are a strong confirmation that the new technologies Agco is developing and incorporating into its high horsepower diesel tractors are the right combination for meeting both the United States Environmental Protection Agency emissions standards and growers’ needs for power, reliability and fuel efficiency,” says Jason Hoult….
A true measure of efficiency, the test results report from Nebraska compared all four models within each Agco, Challenger and Massey Ferguson series to competitive tractors.
Rather than simply measuring fuel consumption in gallons per hour to evaluate fuel efficiency, the evaluation also took into consideration engine displacement and load.
The resulting measurement of horsepower hour per gallon (horsepower divided by hours per gallon) represents the horsepower produced for every gallon of fuel burned per hour. The higher the horsepower hour per gallon, the more fuel efficient the tractor is….
“Horsepower hour per gallon really provides a more accurate picture of fuel efficiency and how the tractor will perform in the field,” Hoult explains.
