Chisel Plow Resets Automatically

The same automatic reset feature used on Kvemeland plows has been adapted to a combination chisel plow-subsoiler. Marketer of the new concept is Dakon, Inc., headquartered in Sioux Falls, S. Dak.

Seven two-rank models are available in widths ranging from 6 ft., 9 in. to 23 ft., 9 in. There are 19 shanks (32 in. clearance) spaced 15 in. apart on the largest unit, which weighs 6,643 lbs. Individual shanks dig to a depth of 18 in.

The two-rank design allows optimum shank spacing for better trash clearance, the manufacturer points out. Hydraulic gauge wheels, for changing tillage depth "on the go" are standard equipment. All models quickly convert from 3-pt. hitch to pull type.

You can increase speed and depth -- without increasing horsepower -- simply by manually lifting one or more pairs of shanks (raising an equal number of shanks on each side to maintain uniform draft). There is no wear and tear on the automatic reset mechanism which remains motionless until tripped. Because of its fixed position, it doesn't have to be greased or oiled.

Dakon officials, in introducing the new concept in deep tillage, offer this explanation of "why it works":

"Today's heavier equipment, and continuous plowing at the same depth, create plow sole or hard pan. This plow sole forms a barrier which seriously hinders penetration and percolating of moisture in the field. Deep tilling breaks up this plow sole, hard pan and wheel compaction and allows moisture to percolate throughout the soil and at the same time retains this valuable subsoil moisture."
