You can cover more acres per day at 10-14 mph (16-22.5 km/h) without compromising the level field finish you expect from John Deere. Covering more acres in a day can also reduce the hours put on your tractor and labor costs, improving your bottom line. With working depths of 2-6 inches (5-15.2 cm), this tool works well in small grains, lentils, and dry corn residue.
