Backswept Liquid Fertilizer Knife with Carbide Insert and Plain Tube

Description

When you’re side-dressing corn or applying liquid fertilizer in the spring, you need a knife that cuts clean, places fertilizer exactly where you want it, and keeps working field after field. This backswept fertilizer knife is built for liquid applications with a carbide insert that stays sharp longer than plain steel—meaning fewer stops to swap out worn knives during busy season.

What You’re Getting

• Carbide insert cutting edge that stays sharp through rocky ground and tough conditions
• Backswept design reduces soil disturbance and plugging compared to straight knives
• 3/8-inch plain tube delivers liquid fertilizer directly to the soil with open discharge
• 13-inch length gives good penetration for proper fertilizer placement
• 2-inch wide cutting edge handles most soil types without excessive draft

Built for Real Farm Work

This knife shines on liquid fertilizer applicators, whether you’re running a pull-type tank or toolbar setup. The backswept angle helps the knife slice through residue and soil while creating a clean slot for fertilizer placement. It’s designed for liquid applications where you want precise placement without bringing up too much soil.

Made to Last

The carbide insert is where this knife really pays off—it’ll outlast regular steel cutting edges by a wide margin, especially in abrasive soils. The forged construction handles the stress of ground contact and the tube is built to take the vibration and flex that comes with field work.

Good to Know

This is a direct replacement that mounts the same as your original knife. The carbide insert means you’ll get consistent performance longer, but when it does wear out, you can replace just the insert instead of the whole knife. Keep a spare insert or two on hand during busy fertilizer season.
