Description
When you’re running liquid fertilizer through your planter, you need a knife that’ll slice through soil cleanly without clogging or wearing out halfway through the season. This backswept fertilizer knife is built to handle the demands of liquid application systems, cutting a precise path for your fertilizer tube while keeping soil flow smooth and consistent.
What You’re Getting
- Carbide insert cutting edge that stays sharp through thousands of acres
- 3/8-inch stainless steel tube resists corrosion from liquid fertilizers
- Chrome carbide tube protector shields your investment from soil wear
- Backswept design reduces soil buildup and improves flow
- 13-inch length provides proper penetration for most soil conditions
Built for Real Farm Work
This knife handles liquid fertilizer applications on everything from corn and soybean planters to specialty crop equipment. The backswept angle helps prevent soil from plugging up around the tube, while the carbide insert cuts through compacted ground, crop residue, and tough clay soils that would dull a standard steel blade in no time.
Made to Last
The carbide insert is brazed on solid and won’t chip or break loose like cheaper alternatives. That stainless tube won’t rust or corrode when you’re running through liquid nitrogen or other aggressive fertilizers, and the chrome carbide protector adds extra life where the tube sees the most wear from abrasive soils.
Good to Know
This knife bolts right onto your fertilizer opener assembly—no modifications needed. The 3/8-inch tube diameter works with most standard liquid systems. If you’re switching from a worn knife, take a minute to check your fertilizer lines for any buildup or blockages while you’ve got things apart.
