Description

When your baler isn’t cutting twine cleanly at the end of each bale cycle, you’re looking at incomplete knots and loose bales—the kind that fall apart before you can get them to the barn. The knotter knife arm is where the magic happens, cutting the twine at just the right moment to complete each bale. When this part starts wearing out, you’ll notice ragged cuts, missed cuts, or twine that hangs up instead of dropping clean.

Built for Real Farm Work

This knife arm handles the constant cycling that happens inside your baler’s knotter box. Whether you’re baling first-cut alfalfa or stemmy prairie hay, this assembly keeps cutting cleanly bale after bale. It’s built to handle the vibration, dust, and rapid movement that’s part of high-speed baling operations.

Made to Last

Knotter components take a real beating—they’re moving fast, dealing with abrasive twine, and working in dusty conditions. This knife arm uses quality materials and precise tolerances to keep that cutting edge sharp and properly aligned with the rest of your knotter mechanism.

Good to Know

Installation typically requires removing the knotter cover and working carefully around the timing mechanisms. Keep track of how everything comes apart—taking a photo before disassembly can save you headaches later. While you’ve got the knotter open, it’s a good time to clean out any accumulated dust and check your other knotter components for wear.
