Higher plant populations and genetically modified hybrids have contributed to a growing residue problem that you are faced with. The key to breaking down residue is properly sizing and mixing it in the top few inches of soil. The new 4500 Series Disc Chisel from Sunflower is aggressive enough to handle even the toughest residue conditions. Hydraulically adjustable front and rear disc gangs can be changed independently of each other, enabling you to fine tune your machine from field to field. Chisel shanks are spaced on 15 inch centers and will reach a depth up to 12 to 14 inches, and are strategically placed for optimum residue flow. The individually mounted disc blades will size and mix the residue, while the shanks will fracture the compaction up to 12 to 14 inches deep and the rear gangs will provide the finish you desire.
