Nebraska Tractor Test Results: What You Need to Know

The Nebraska Tractor Test Lab has been a benchmark for tractor performance since 1920.

Located at the University of Nebraska-Lincoln, the lab tests tractors to determine their power, efficiency, and durability.

The lab's testing process involves a variety of evaluations, including engine power, hydraulic output, and fuel consumption.

One key aspect of the test results is the Power Take-Off (PTO) horsepower, which measures a tractor's ability to power implements.

The lab's results are widely respected and used by farmers, manufacturers, and researchers to make informed decisions about tractor selection and design.

The Nebraska tractor tests are a benchmark for evaluating the performance of tractors, and the results are fascinating. The Steiger Quadtrac 620 Tier 4B achieved a maximum drawbar fuel efficiency of 16.63 hp-hr./gal. at rated engine RPM.

The John Deere 9620RX Tier 4B, on the other hand, had a maximum drawbar fuel efficiency of 15.54 hp-hr./gal. at rated engine RPM. This is a notable difference, especially considering the Steiger Quadtrac 620 Tier 4B was more efficient even at 75% pull.

The Steiger Quadtrac 620 Tier 4B also had a maximum observed drawbar horsepower of 561.94 hp, which is significantly higher than the John Deere 9620RX Tier 4B's 549.55 hp. This is a key factor in determining a tractor's overall performance.

The Steiger Quadtrac 620 Tier 4B had a maximum pull of 57,556 lb., while the John Deere 9620RX Tier 4B had a maximum pull of 53,349 lb. This is a notable difference, especially considering the Steiger Quadtrac 620 Tier 4B's higher horsepower rating.

The Steiger 620 Tier 4B had a maximum drawbar fuel efficiency of 17.63 hp-hr./gal. at rated engine RPM, which is even higher than the Steiger Quadtrac 620 Tier 4B's efficiency. This suggests that the Steiger 620 Tier 4B is a highly efficient tractor.

The John Deere 9620R Tier 4B, on the other hand, had a maximum drawbar fuel efficiency of 16.07 hp-hr./gal. at rated engine RPM, which is lower than the Steiger 620 Tier 4B's efficiency. This is a notable difference, especially considering the Steiger 620 Tier 4B's higher horsepower rating.

The Steiger 620 Tier 4B also had a maximum observed drawbar horsepower of 594.08 hp, which is significantly higher than the John Deere 9620R Tier 4B's 556.83 hp. This is a key factor in determining a tractor's overall performance.

The Steiger 620 Tier 4B had a maximum pull of 65,077 lb., which is significantly higher than the John Deere 9620R Tier 4B's 60,455 lb. This is a notable difference, especially considering the Steiger 620 Tier 4B's higher horsepower rating.

The Nebraska tractor tests also evaluated the total operating cost of the tractors, and the results were surprising. The Steiger Quadtrac 620 Tier 4B had a 2.1% lower total operating cost than the John Deere 9620RX Tier 4B, based on a weighted average of $0.0023/hp-hr.

The Nebraska Tractor Test results are a treasure trove of information for anyone looking to optimize their tractor's performance. The Steiger Quadtrac 620 Tier 4B achieved a maximum observed drawbar horsepower of 561.94 hp. This is a notable difference from the John Deere 9620RX Tier 4B, which reached a maximum observed drawbar horsepower of 549.55 hp.

Fuel efficiency is also a crucial factor to consider when selecting a tractor. The Steiger Quadtrac 620 Tier 4B boasts a maximum drawbar fuel efficiency of 16.63 hp-hr./gal. at rated engine RPM. In comparison, the John Deere 9620RX Tier 4B reached a maximum drawbar fuel efficiency of 15.54 hp-hr./gal. at rated engine RPM.

Maximum pull is another key metric to evaluate when choosing a tractor. The Steiger Quadtrac 620 Tier 4B achieved a maximum pull of 57,556 lb., while the John Deere 9620RX Tier 4B reached a maximum pull of 53,349 lb. This is a significant difference in terms of the weight the tractors can handle.

The Steiger 620 Tier 4B also outperformed the John Deere 9620R Tier 4B in several areas, including maximum observed drawbar horsepower and maximum pull. The Steiger 620 Tier 4B achieved a maximum observed drawbar horsepower of 594.08 hp, while the John Deere 9620R Tier 4B reached a maximum observed drawbar horsepower of 556.83 hp.

Overall, the Nebraska Tractor Test results provide valuable insights into the performance of various tractors. By examining these results, you can make informed decisions when selecting a tractor for your needs.
