J&M Manufacturing wins gold manus with iglide plain bearings!
The problem is that the knife is behind the coulter and swings up out of the ground faster than the blade. This can cause some of the nitrogen to volatilise and be lost as fertilizer. To solve this problem, J&M Manufacturing engineers developed a spring-loaded system. The design keeps the knife and blade at the same level with respect to the ground when engaging, so more nitrogen stays in the soil.
