The 2995 Xtreme Fertilizer Coulter (XFC) is capable of high-speed fertilizer application in tough soil conditions. The coulter’s design delivers spring pressure up to 2,000 pounds, providing the down pressure needed to cut through difficult soil conditions. The XFC is designed to be mounted on toolbar fertilizer equipment.
Knife or Injector
Use less than 30 PSI to reduce the amount of splattering.
Set the rod to operate at 1/2" below soil surface.
Center the blade on the hub so that it is concentric when it turns. Place the knife top up to the coulter blade so the knife and coulter blade just slightly contact each other at the tip. Then, as the coulter blade rotates up the knife, you want to have a gradual gap between the knife and coulter blade. Also, the knife needs to be centered side to side on the coulter blade.
In some conditions, a knife scraper is needed to keep the residue from dragging up on the fertilizer knife.
