'Until such time as a tractor could be tested, the
manufacturer was granted a temporary permit to sell tractors
subject to the results of the tests. As a result, some 93 tractors
were offered for test, and the work of testing them at the
university began early this spring.

'Owing to the fact that a number of tractor manufacturers
who were entered previous to ourselves were unable to get their
tractors ready for the tests at the appointed time, we entered
ahead of our turn. Our tractors were shipped the early part of
June, arriving at Lincoln Saturday night, the 26th, when Mr. Hoig
of the Lincoln branch wired us and immediately Mr. Cedarburg and
myself went out there to arrange the tests.
'It was necessary for us to run the tractors out to the
state grounds some three miles from the center of the city before
bolting on the lugs. As a result of the delay, we did not get the
first tractor started on the limbering up run until Wednesday
morning, the 30th. During the entire time of the tests, there were
always delays due to rains and other unavoidable happenings, so
that we were nearly three weeks making the entire series of runs,
which, however, were successfully completed without any especially
exciting event, except that our 30-60 first broke the spring in the
traction dynamometer, tore the 10-inch belt down about 40 feet of
its length. There were no casualties suffered by this accident,
although one of the testers came very nearly being spanked to
death.
'The following excellent performance of our several
tractors, as taken from the official reports, speak for
themselves:
15-30 Tractor Maximum horsepower on the belt, 34.37
Maximum drawbar horsepower, 21.19
22-45 Tractor Maximum horsepower on the belt, 46.66
Maximum drawbar horsepower low gear, 28.10
Maximum drawbar horsepower high gear, 25.58
30-60 Tractor Maximum horsepower on the belt on kerosene,
75.49
Maximum horsepower on the belt on gasoline, 80.10
Maximum drawbar horsepower on kerosene, 55.35
Maximum drawbar horsepower on gasoline, 58.05
'To give us enough load during the maximum test of the
30-60, we pulled, in addition to the dynamometer car, an Avery
18-36, our own 22-45 with clutch in and the engine turning, two
stone boats, each loaded to 1,500 pounds weight, and a pair of
heavy rolls with concrete. The entire load made quite a dignified
looking procession, and caused no end of comment. At the time this
test was run, the track was covered with dust to the depth of over
three inches, but owing to the design of the lug equipment used on
our drive wheels slippage was but 4.3 percent, which established a
new low slippage record for this track. It is interesting to note
that our 30-60 is the most powerful tractor tested by the
university.
'There is, of course, a very considerable degree of
opposition to these tests among manufacturers whose tractors do not
come up to their ratings, but there are a good many, who, like
ourselves, really build tractors capable of satisfactorily doing
everything claimed by them, who welcome this opportunity of getting
an official test on so scientific and unvarying a basis.
