One lost or broken part can stop you plowing for the day. It can be as simple as clevis or pivot pin. Mill Supply carries just about every clevis pin the Western plows use from 3/4" x 3-1/2" to 1" x 5" and all the cotter pins, groove pins and lock pins. In addition to the pins we carry the trip springs, eyebolt that hold the springs. We usually ship the same day if your order is called in before 3pm so you can get your plow up and running as soon as possible.
