The pilot said he was spraying a milo field, 3 miles southeast of Superior, Nebraska. While in a turn to south, 'the engine started to sputter and miss. Smoke started coming out of the left hand side of the engine ... a substantial power loss followed.' The pilot turned the airplane to the north and attempted to put down in an alfalfa field. During the landing attempt, the airplane struck some hay bales and a tree. An examination of the airplane's engine revealed a cracked exhaust valve on the number 7 cylinder. No other anomalies were found.
