The firm's tractors received considerable favorable
publicity as a result of the records they made in tests,
particularly those staged at Winnipeg, Fremont, and Lincoln. In
1912 the company's tractors were submitted to tests at Winnipeg
and were proved to be superior. At the Fremont Power Demonstration
in 1917, Aultman & Taylor tractors pulled one 14-inch plow
seven inches deep for each 3 HP drawbar rating. It was claimed that
the Aultman & Taylor tractors at that demonstration showed
approximately 20 percent greater efficiency than any of the other
tractors entered.

Then in 1919 Nebraska enacted a law that any company that sold a
tractor in Nebraska was required to submit that tractor to tests.
Those tests were conducted on the state fairgrounds at Lincoln
during the latter part of June and the early part of July in 1920.
The description of those tests is presented in considerable detail
in a statement written by W.H. Worthington, who was the
company's chief engineer: 'In the early part of last year
(1919), Nebraska put into effect a law designed to encourage the
manufacture and use of improved types of tractors, and to
contribute to their more successful adoption for farm purposes, and
at the same time to protect the farmer against untrue and unfair
claims regarding any tractor offered for sale. In order to check
the claims and statements made by the manufacturer, it was decided
that a stock tractor of each model sold within the state should be
tested and passed upon by a board of engineers under the management
of the state university.
'The test on each tractor was run in seven parts as follows:
First, each tractor was given a running in or limbering up period
of 12 hours on a dirt track, during which time it pulled a load
ranging from one-third to its full rated drawbar horsepower.
Second, the tractor was taken indoors and belted to a Sprague
electric dynamometer where it carried its rated belt load at rated
speed for two hours. Following the rated load run on the belt was,
third, a one hour variable load test wherein the tractor developed
from no load to full load, and, fourth, one hour run at one-half
rated load, followed by, fifth, a one hour maximum load run with
the governor wide open. After having passed these indoor tests, the
tractor was taken to the cinder testing track where the sixth part
of the test was applied by causing it to pull its rated drawbar
load for a period of 10 hours. This rated drawbar run was
immediately followed by, seventh, a maximum load test which
consisted of a series of short runs with increased load for each
run until the engine was either overloaded or the drive wheel
slipped excessively. The drawbar horsepower of the tractor was
measured by means of an electric dynamometer car especially
designed and built by the university for the running of these
tests. The draft of this car could be changed at will with a
maximum limit of 5,000 pounds so that any desired load could be
applied and maintained. A regular Gulley traction dynamometer was
built into the hitch of this car in such a way that the exact pull
of the tractor in pounds, together with the number of feet
traveled, could be measured and recorded.
