At a truckstop in Indianapolis this morning was talking to a fellow from Ohio, who will be participating in a plowing contest near Des Moines. His JD 2030 (?) will be pulling a two bottom Kunerlan (sp?) Norweigan plow at approx 1 1/2 mph. A major factor in grade system is levelness. Each plowshare is 6 1/2' long. Sounds interesting. Herb
