Disc coulter for no till planter

A disc coulter is the first point of soil contact on a no-till planter or seed drill, designed to slice through heavy crop residue and open a narrow slot for the seed furrow. In conservation tillage systems, this sharp, rotating disc cuts through corn stalks, wheat straw, or cover crops, preventing hair-pinning and allowing the double‑disc openers to place seed at a consistent depth.

Disc coulters are manufactured from high‑strength, wear‑resistant materials, including hardened 1080 carbon steel, boron steel, and 65Mn manganese steel, with heat‑treated edges to withstand rocky conditions and high‑speed planting. Edge designs include smooth (plain) for clean slicing through standing stubble, notched for aggressive residue cutting in heavy trash, and rippled (wavy) for slight soil fracturing and improved residue flow.

Available as individual replacement blades or complete assemblies with hub and bearing, these coulters fit a wide range of planter and drill brands, including John Deere, Case IH, New Holland, Kinze, White, Yetter, Great Plains, and Land Pride.

For precision planting, residue management, or upgrading to no‑till, a sharp, properly maintained disc coulter ensures consistent seed depth, reduced downtime, and maximum yield potential.
