The largest model in Case IH’s range of wheeled tractors has set new records in the USA.
The tractor was recently subjected to testing at the University of Nebraska Tractor Test Laboratory (NTTL) – a tractor testing facility which is known around the globe. The NTTL routinely tests tractors and compares the results to the manufacturers’ own performance claims.
Results from the tests on the Steiger 620 – the wheeled equivalent of the Quadtrac 620 – have shown that the machine is the most ‘fluid-efficient’ and exhibits the highest drawbar horsepower of any tractor tested so far.
New records set by the 620 include those for drawbar fuel efficiency, drawbar horsepower and maximum pull. In each category, Case IH’s beefy Steiger 620 outperformed all tractors previously tested at the facility.
In addition to the highest horsepower figure – 594.08hp – yet recorded at the NTTL, the Steiger 620’s claimed ability to efficiently transfer power to the ground was backed up by a maximum drawbar fuel efficiency figure of 242g/kWh, and the production of 75% of maximum pull power at 257g/kWh.
That fluid efficiency, making the most economic use of both diesel and diesel exhaust fluid (DEF/AdBlue), translates directly into lower operating costs, according to Ulrich Sommer, Case IH’s Steiger Tractor Marketing Manager.
Those figures are backed up by similar results from the next model in the Steiger range – the 580 – which scored the second-highest drawbar fuel economy figures ever recorded at the facility – at 243g/kWh. That figure was 6.63% lower than the tested competition in its power class.
“Case IH Steiger and Quadtrac engines, made in-house by Case IH’s sister company FPT, feature a design in which there is no particulate filter to clean, no regeneration period and 600 hours between oil changes. That translates to average fluid operating costs (diesel plus DEF) that are 2.2% lower across the 370-620hp Steiger tractor range – when measured against comparable competitor models.”
The NTTL is the officially-designated tractor testing station for the United States. It tests tractors according to the Organisation for Economic Co-operation and Development (OECD) codes. 29 countries adhere to the OECD tractor test codes, with active testing stations in 25 countries around the world.
