PLENTY OF CLEARANCE. Deereâ??s new strip-till unit offers high clearance for use in continuous corn residue. With 25-inch coulters set on 15-inch spacings to size residue, the unitâ??s 16-inch row cleaners remove residue ahead of the nutrient shank.

New Equipment Ideas For No-Tillers

John Deere has introduced several new products of special interest to no-tillers.

Finally Recognizing the popularity of strip-till and the growing demand for this type of specialized equipment in continuous corn, John Deere has made a late entry into the market with its first machine.

“Once the residue has been sized, spring-cushioned 16-inch row cleaners remove residue from the row ahead of the nutrient shank,” explains Wendt. “The notched disc blade on the row cleaners can be adjusted vertically, depending on how aggressively the cleaners need to operate. The spring-cushioned nutrient shank then places nutrients into the root zone.”

The nutrient shank’s 1,300-pound trip force allows faster operating speeds while maintaining a consistent seedbed and nutrient placement in the root zone. The maximum operating depth…
