The above actual horse powers were obtained from the Nebraska Tractor Tests records. The Nebraska Tractor tests were the only tractor testing labs in the world for many years. They were begun in 1920. The tractor must complete & pass the tests to be sold in the state of Nebraska. They had to preform without probelms & to or beyond their rated horse power. The Rumelys never had any problem meeting horse power requirements as you can see.
