Description
If you’ve been dealing with ragged cuts or noticed your disc mower isn’t performing like it used to, worn drum knives are usually the culprit. These twisted blades are what do the actual cutting as they spin at high speed, and when they get dull or damaged, your hay quality suffers. This right-hand drum knife brings back that clean, precise cut that keeps your forage looking good and your livestock happy.
What You’re Getting
- Precision-crafted 11-degree twist that creates the proper cutting action and helps move material through smoothly
- Right-hand clockwise rotation design that matches your mower’s drum setup perfectly
- 4.2-inch length and optimized thickness for durability without adding unnecessary weight to the spinning assembly
- Direct replacement quality that installs just like the original with no modifications needed
Built for Real Farm Work
This knife fits disc mowers from Vicon, Agco, and other brands that use this bolt pattern and rotation. Whether you’re cutting first-crop alfalfa, mixed grass hay, or thick pasture growth, this blade handles the variety of crops and conditions you’ll encounter during haying season.
Made to Last
Farm equipment knives take a beating from rocks, dirt, and tough stems, so this one’s built to handle it. The hardened steel construction and proper heat treatment give you the edge retention and impact resistance you need for season after season of reliable cutting performance.
Good to Know
These knives work in pairs—this right-hand knife pairs with the left-hand version for complete drum coverage. When replacing knives, it’s smart to do them in sets to keep your cutting action balanced. The 11-degree twist is critical for proper material flow, so don’t substitute with straight blades if you want optimal performance.
