A 1928 Koehring Dumptor: If you look for one of these anywhere else, you're likely to be disappointed. "It's very rare; one of a kind," said Flywheelers president Dick Edwards. Flywheelers member Lew Donaldson – also a member of the Antique Construction Equipment Club – found the Dumptor in Grand Rapids, Mich. The unit was originally used in road construction, particularly in sandy areas where other equipment might get bogged down. Manufactured in Milwaukee, Wis. (serial number 122), the Dumptor is powered by two 10-20 McCormick-Deering tractor engines, one on each track. It hauls five cubic yards, and weighs more than 20,000 pounds. "It was all complete but one magneto when we got it," Lew said. "We had to rebuild both engines; it hadn't run since '55. And both tracks were stuck solid; they wouldn't turn." Lew got the Dumptor to Flywheeler Park in January. With help from several enthusiastic assistants, the unit was up and running about a month later.
