Vertical tillage redefined

02/28/2011 @ 1:52pm

No matter what type of tillage practice you employ on the land, each disc that touches the dirt has to be sharp enough to cut through the previous season's crop residue.

Ingersoll Tillage Group, which is located in Boulder, Colorado, recently introduced a new innovation, the SoilRazor VT, that could redefine one of those practices — vertical tillage. Company representative Steve Kertesz says it's the unique design that makes this tool a breakthrough technology for the vertical tillage industry.

In general, vertical tillage blades are straighter, more like coulters, and often fluted. What sets one apart from the other is the degree of curvature and the amount of fluting as well as the angle of the gangs, which varies by manufacturer.

But Ingersoll is taking that design concept to the next level.

“The disc's unique serrated edge design remains sharp through use, providing a long-lasting cutting edge that maintains its ability to slice and size the toughest residue as it wears,” Kertesz says. “Even at the highest speeds, the SoilRazor VT retains its durability and sharpness.”

The SoilRazor VT is made with a proprietary boron steel alloy, which is coupled with Ingersoll's processing technology, to provide the end user with a tool that is not only hard, flexible, and sharp but also is wear-resistant. In fact, the proprietary boron steel delivers a Rockwell hardness up to 52 RC without causing brittleness or loss of elasticity.

This disc can slice through genetically modified corn and soybean residue, as well as wheat and barley straw.

Leveraging A Concept

To leverage the patent-pending concept, the company worked with select original equipment manufacturer (OEM) partners, like AGCO Corporation ( and Krause Corporation (, to develop new products.

“Prior to this, a stay-sharp blade that performed in this way was unheard of in our industry,” says Larry Kuster, senior marketing specialist for AGCO Corporation. “We began using this technology in our Saber blade and demonstrated our prototype with 3,000 acres on it to crop producers last fall. When they saw the results, they were very excited.”

A similar response came from Krause customers. “Our customers recognize a difference in this blade, and the response has been very positive,” says Curt Davis, marketing manager for Krause Corporation.

The company is the developer of the new Excalibur blade that also leverages SoilRazor VT technology.

“The serrated edge is able to capture and slice residue very effectively. Most disc blades have rounded edges that allow residue to slide off easily,” Davis says.
