JOHN DEERE HIGH SPEED DISK

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.
