Coulter
A coulter is a blade used in plowing or seedbed preparation. It is mounted in front of the plowshare and is designed to cut through soil, crop residue, and weeds before the main cutting edge engages. This front cut helps reduce soil clogging, improves penetration, and produces a cleaner furrow. Coulters are common in various plowing systems, including row crops and conservation tillage, and may be rigid or spring-loaded to match soil conditions.
Coulter is also a surname. Notable people include Ann Coulter, an American conservative commentator and author,
