The Case IH Steiger 620 has been proven the most fluid-efficient and highest drawbar horsepower tractor in the world by recent tests at the University of Nebraska Tractor Test Laboratory (NTTL).  The 620 set new records in drawbar fuel efficiency, drawbar horsepower and maximum pull.

“It’s one thing to generate a lot of horsepower,” said Mitch Kaiser, Case IH Steiger tractor marketing manager. “But it’s just as important to efficiently transfer that power throughout the tractor and, ultimately, to the ground and to the implement you’re pulling. That fluid efficiency — including diesel fuel and Diesel Exhaust Fluid (DEF) — translates directly to lower operating costs.”

In addition to the Steiger 620 achieving the highest marks recorded for any tractor ever tested at NTTL, the Steiger 580 scored the second-highest drawbar fuel economy ever recorded* at 17.53 horsepower hours per gallon — 6.63 percent higher than the tested competition in its power class.  The complete Steiger tractor lineup (370 to 620 horsepower) features best-in-class power, torque and fluid efficiency.
