On Sept. 13, 2011, James Langholf, employed by Howe Freightways Inc., was driving a semi-tractor and trailer truck through Iowa when he heard a pop and felt the engine shake. He then noticed black smoke coming from the engine. He had the engine powered on but pulled off to the side of the road and called Howe’s director of safety and maintenance and the shop foreman for help.
Langholf could not restart the engine and was told to call Cummins, the manufacturing company for his truck’s engine, which had a repair shop nearby.
On advice from someone at Cummins, Langholf called Hanifen Co. in Des Moines to get a tow. Hanifen was 53 miles away and farther than two other tow companies. Two trucks were dispatched, as two were needed to tow the semi-tractor and trailer.
