Description
When you’re cutting hay and the drum knives start dulling or chipping, you know it’s time for fresh blades. Dull knives don’t just slow you down—they leave ragged cuts that don’t dry evenly and can stress your plants. This domed drum knife gives you that clean, sharp cut that helps your hay cure properly and keeps your mower running smooth.
What You’re Getting
- Domed blade design that cuts cleanly through thick stems and tough crop conditions
- 4.2-inch length with precise 1.9-inch width for optimal cutting performance
- CW/CCW rotation capability means you can use it on either side of the drum
- 21mm bolt hole that fits securely without wobbling or coming loose during operation
- Quality construction that holds its edge longer than bargain blades
Built for Real Farm Work
This knife is designed to fit PZ-Zweegers and AGCO disc mowers—reliable machines that farmers count on to get through acres of hay and forage crops. Whether you’re cutting alfalfa, grass hay, or mixed stands, this blade handles the variety of stems and conditions you’ll encounter in real field work.
Made to Last
The domed shape isn’t just for looks—it helps the blade slice through material more efficiently while reducing wear on the leading edge. At 3.0mm thick, it’s built to take hits from rocks and debris without cracking or chipping easily.
Installation Notes
This is a direct replacement that bolts right on with your existing hardware. The 0-degree twist design means no special orientation worries—just make sure the dome faces the right direction for your cutting rotation.
