Single-Frame Hydraulic Locking Toolbar

Use less than 30 PSI to reduce the amount of splattering.

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.

We don't lose nitrogen through nitrification

"We concluded that for our no-till operation, we needed to get fertilizer deeper into the ground. Because the Yetter injection system places the fertilizer in the ground, we don't lose nitrogen through nitrification or because it sits on the top of the residue. They've provided a big cost benefit because they've lowered our nitrogen needs per bushel. Yetter coulters are also are a pretty fuel-efficient option.

"I like Yetter products because they are well-researched and the designs advance with the times. Yetter sales reps are great—always willing to help me execute new ideas."
