Feed Mixer Knife Tips

Maintenance Monday

Welcome to another Maintenance Monday from Hanlon Ag Centre! Shane is back with practical advice for farmers in southern Alberta on getting the most out of your feed mixer knives.

Why Extra Knives Aren’t Always the Answer

There’s a common misconception that simply adding more knives to your mixer will improve cutting. Shane explains that this isn’t always true. Adding extra knives often just moves the material around the tub faster rather than cutting it more efficiently. Instead, consider installing extended backers, which move the knives 3–4 inches forward and place them in a better position to cut the material as it comes down.

Using Moisture to Improve Cutting

If your feed mix is dry — like hay, straw, or green feed — adding some moisture can make a big difference. Moisture creates friction along the tub walls, slowing down the material just enough to improve cutting efficiency. The result is better processed feed and more palatable feed for your animals.

Need Help?

If you’re still running into cutting issues, Shane recommends reaching out to your sales rep. They can walk you through specific adjustments to improve performance and ensure your feed mixer is operating at its best.
