"Just like many of us, farmers have looked to technology to make their jobs easier. In the 18th century, farmers used horses and oxen to pull wooden plows. In 1837, John Deere started producing steel plows and in 1868 steam tractors were invented that no longer needed horses or oxen. Then, John Froelich invented the first successful gas-powered tractor in 1892. Today tractors are used when planting, fertilizing, harvesting, and moving items around the farm. Over 120 years later and tractors are still helping farmers and ranchers perform many agricultural tasks." - American Farm Bureau Foundation, Purple Plow Puzzler #26.

The Challenge: Design and build a cardboard tractor that will travel in a straight line when released from an incline position without assistance. Success will be determined by measuring the distance the tractor travels along the straight line from the point of release to the point where the tractor veers from the path of travel.
