No matter what type of tillage a farmer employs, each disc has to be razor sharp in order to cut through last season's crop residue. That's why every Ingersoll disc is precious machined using automated edge-turning equipment. Carbide cutters create a razor sharp knife edge. This process allows us to make the Residue Razor™ that's five times sharper than conventional blades. These discs can effortlessly slice through genetically engineered corn and soybean residue, wheat and barley straw. For maximum tillage control and fuel efficiency, a disc has to be Ingersoll sharp.
When a disc hits a hard object, something has to give. It should never be the disc. Broken discs can cause a world of problems in the field and require time-consuming maintenance to replace. That's why Ingersoll discs are made with a unique boron steel alloy. you won't find very many things in the Universe harder than our boron steel. In fact, some boron compounds can even scratch a diamond. At Ingersoll, we've developed our own exclusive boron steel that delivers a Rockwell hardness up to an astonishing 52 Rc without causing brittleness or loss of elasticity. Compared to high carbon steel, there's just no comparison. To reduce the risk of broken discs, there's no substitute for Ingersoll hardness.
When a disc hits a hard object that it can't cut, it has to yield the right of way. That's why it's so important for ground engagement equipment to be engineered for the ideal compromise between hardness and flexibility. Ingersoll discs have achieved this near-perfect balance with finished discs that are continually tested for flexibility and have the ability to withstand stress and fractures. The result is a level of field-proven reliability that can't be matched. That's why farmers the world over demand Ingersoll quality. On that point, they're just not flexible.
