Deere's 8R series raises bar with fuel-efficiency records
At this year's Lamma Show, John Deere announced that its 2010 8R series tractors have broken fuel-efficiency records for large row-crop tractors at the Nebraska Tractor Test Lab (NTTL) in the USA.
The firm claims that it has achieved leading fuel-economy results in four out of the five tests at the Nebraska facility, which are designed to represent how these tractors are used in the field.
According to John Deere, in autumn 2009, an 8320R broke the 8430 model's record as the most fuel-efficient row-crop tractor ever tested in the rated engine speed PTO test.
The company added that the remaining 8R and 8RT models introduced for last year were recently assessed. Of these, the 8295R set a new fuel-efficiency record of 225g/kWh in the rated engine speed PTO test. This was achieved at a rated engine speed of 2,100rpm. Speed at the PTO was 1,048rpm. John Deere said this beats its 8320R's figure of 228g/kWh.
The company said that the 8295R also set NTTL records as the most fuel-efficient large row-crop tractor in the drawbar tests for maximum power, 75pc and 50pc of pull at reduced engine speed.
The company states that it also came within 5g/kWh of the leader of the test at 75pc of pull at maximum power.
