Non-Freeze Side Mount

We offer fertilizer knives in both knock-on and bolt-on models. All models are compatible with various cultivators. The adjustable blade on our fertilizer knives allows you to easily control the depth of your fertilizer and all NH3 Series blades can be adjusted up to 1″ for wheel tracks. This feature also accommodates replacement of the point without having to change out the entire knife. NHK Series fertilizer knives are carbide-tipped for extended wear. Each knife has a 1/2″ thick high-carbon shank, the best available on today’s market. When you do have to replace your knives, it’s easy – just a bolt and a nut.
