Basic straight cut coulters on a weighted gang in the front of the unit cut and size the residue. The chisel shanks, spaced on 15" centers and equipped with twisted chisel points, engage the soil and mix and blend the sized residue into an acceptable medium for preventing erosion and conserving moisture. These tools will leave the surface ridged allow more surface to be available to the sunlight for the better dry down and warm up before the next planting season.
The CD models are the original Soil Builders. A single, manually adjustable gang of coulters with 7 1/2" spacing in the front of the machine starts the tillage process. Two ranks of chisel shanks are supported on a weighted frame that allows for 15" shank spacing. The shank and coulter spacing allow one coulter to lead each shank and have one coulter in between each shank for optimum soil breakout and residue flow. The CD series is available in 5 and 7 shank models. These machines fit very well with 100 to 150 HP tractors in most conditions.
The HSB series is the next generation of Soil Builders. many of the proven components and features from the CD series have been incorporated into the HSB models. The coulter gangs have remained unchanged other than they are hydraulically controlled. The chisel shanks are mounted to a 3-rank frame for added residue capacity. the lift axle is controlled with a single depth stop cylinder. Walking tandems are available on the larger units. The hitch is longer to accomodate larger tractors with dual tires. The HSB models are available in 7, 9, 11 and 13 shank models. Horsepower requirements are 15 to 20 HP per shank.
