Mud Scraper For Dual Truck Tires
Minnesota farmer Lowell Schwitters, of Raymond, solved the problem of mud build-up between dual truck tires with a mud scraper that attaches to the truck frame.
"The scraper keeps mud off the tires, making the truck lighter and helping keep the highways mud-free," says Schwitters. His idea was the top vote getter in the Growers Idea Contest, sponsored by the Sugarbeet Research and Education Board of North Dakota and Minnesota.
Schwitters welded a 19 in. long piece of 2 by 2 in. steel tubing to the truck frame. From that, he bolted a bracket made of flat stock. The 12 in. long, 1 by 2 in. steel cleaning bar attaches to the bracket and pivots from side to side to compensate for wheel oscillation.
The scraper for each set of rear duals points toward the front tires at about a 40? angle, extending down 8 in. from the top of the tire. For the back set of duals, Schwitters attached mud flaps to the scraper frame.
He notes that he leaves the scrapers on year round, though they remove easily.
