Freezeless Fertilizer Knives

Harvesting later than you wanted to? Finishing up patches later than normal? Is post-harvest moisture causing freeze-ups on your ammonia bar? ShieldAg agricultural machinery manufactures a complete line of patented frostless fertilizer knives for NH3 systems in tough wet and frozen-ground conditions. These tough knives pull easily and perform in the toughest conditions. Available as a one-time-use (fully welded) knife or with pin-on replacement points to increase value and reduce down time. If you need to run a dual application, our freezeless knives come with a tube saver set up to handle a second tube with chrome casting built in to protect it.
