KNIFE; STANDARD, CHROME TOE, 3/8" SS TUBE, SFE

Product Description

The Standard SFE Knife combines the classic durability of our standard chrome-toe knife with an advanced Sealed Fertilizer Emitter (SFE) design. This knife is engineered to maximize the retention of anhydrous ammonia (NH3) by creating an immediate and effective seal behind the injection point, drastically reducing gas loss and boosting application efficiency. Features a specialized tip geometry or closing component designed to improve the mechanical seal of the fertilizer slot immediately after injection. This is critical for minimizing NH3 volatilization and maximizing nutrient availability. The primary wear point is reinforced with a high-chromium hardfacing. This Chrome Toe provides extreme resistance to abrasive soil conditions, significantly extending the knife’s service life and lowering maintenance frequency. Equipped with a precision 3/8-inch delivery tube made of Stainless Steel. This ensures maximum resistance to corrosion from anhydrous ammonia, guaranteeing clean, reliable flow and longevity. The robust, traditional knife body ensures deep, consistent soil penetration and stability, delivering your nitrogen exactly to the target root zone depth. By combining the superior wear life of the chrome toe with the gas-saving efficiency of the SFE, this knife provides optimal cost-effectiveness season after season.

Choose the Standard SFE Knife for premium durability and a technological edge in minimizing costly NH3 loss.
