How can the Ford 8870 be the most efficient (tested in 1996) when Deere's 8430 broke the world's record in 2006. 298 horse at 18.65 HHG.
I just read through some archives, and when the New Holland 8870 was tested at Nebraska asking Deere and Case, it lost to both and it was nowhere near 20 horsepower hours per gallon. Here's a piece of the article:
From Farmers Journal 1998 : "In the Nebraska tests, the New Holland 8870 were compared with equivalent models from John Deere and Case. Across four models, the New Holland fuel economy figures were coming in below the others in each sector. The differences ranged from 11 per cent for the smaller models to 13 per cent for the bigger ones."
And here's one about Deere breaking the fuel-efficiency record - which they broke again this year:
Fuel Efficiency Record Set By John Deere 8430 Tractor In Nebraska Test Lab LENEXA, KS (July 14, 2006) — John Deere recently tested an 8430 Tractor, rated at 250-PTO hp, at the Nebraska Tractor Test Lab in Lincoln, Neb. to independently verify fuel efficiency, power, and performance. Record-setting results were returned for fuel efficiency on the 8430 Tractor with Automatic PowerShift Transmission (PST) for power produced to fuel consumed of any row crop tractor ever test The tractor was equipped with an Automatic PowerShift transmission and tested at 100 percent PTO load at rated engine speed. The record result of 18.65 Hp.-hr./Gallon was achieved. Previously, the 8520 Tractor with the same equipment had test results of 17.13 Hp.-hr./Gallon. This 8.8 percent improvement is now the benchmark for tractor fuel efficiency performance in a row crop tractor.

Today's Featured Article - New Life for an Old Allis - by Tyler Woods. My friend Jon, has an old '39 Allis Chalmers B. He thought it a marginal tractor that had long since served its time. She smoked terribly and never had much power but he couldn't afford another so he was limping along with what he had.
