Tractor lab tests manufacturer claims
By Dave Madsen
Besides 13 iy Red football, UNL has
something that no other U.S. college or
university has -a tractoi testing program.
According to Milo Mumgaaul, assistant
professor in the department of agricultural
engineering, the testing program at East
Campus is the only such program in the U.S.
It is designed to validate ciauns by ti actor
manufacturers as to the performance of their
tractors, Mumgaard said. He said that all
tractors sold in tin; state must be approved by
it.
He said the UNL testing facility began
operation in 1919, as one of the first consumer
testing pro trams in the world. Ho said it was
started because farmers had no way of testing
tractor manufacturers' claims.
Some of the ilems tested aie horsepower,
fuel consumption, diawbar peiloimance and
noise level of the liactor during use.
"Oui testing piogram lias a very good
reputation," he said. "Until Wuili.l War II, we
bad the only testing center in the wot Id. Since
then othei countries have developed testing
programs, but they'ie ail based on Nebraska's
(p'ogi a m)."
Mumgaard said the four full time staff
members with the program have tested foreign
tractors as well as U.S. models.
He said it takes about one week to run a
tractor through the various tests. Probably 40
tractors will fx; tested this year, Mumgaard said,
but he said this is a very large year. He said that
last year about 30 tractors were tested.
Four years ago, about one out of every foui
1i actors tested didn't pass," Mumgaard said. He
said he wasn't sure about figures lor more
recent years.
He said that most of the tractors that fail
the tests do so because they don't meet the
manufacturers' horsepower claims.
"One company claimed about 1b'
horsepower more than the tractor could
deliver," he said. "They were foiced to change
their claim in that aiea."
The tractor testing progiam is
self-supporting, accoiding to Mumgaard. Each
company that wishes to have a tractoi tested
must pay a base fee, plus an additional chaige
in accordance with the hoisepowei of tin;
tractor.
He said that last year the average chaige for
each tractor was $3,000, but it would be l'-.s
this vear because smaller tractors aie brum
tested.
