Description
If your mower’s cutting action isn’t quite as smooth as it used to be, or you’re hearing some rattling coming from the cutter bar, there’s a good chance your knifehead pin has seen better days. This pin is the pivot point where each knife section attaches to the balanced head, and when it wears out, you’ll know it—your hay quality suffers and the whole machine vibrates more than it should.
What You’re Getting
- Grease zerk with 1/8″ pipe thread keeps things properly lubricated during long cutting days
- Precision-fit pin that eliminates the play and wobble that develops with wear
- Hardened construction designed to handle the constant reciprocating motion of the knife
- Direct replacement that gets you back to cutting without modifications
Built for Real Farm Work
This pin is made for Case International 100 Series balanced head mower conditioners, the workhorses you see cutting hay and forage crops across farm country. These machines need smooth, precise knife action to make clean cuts that help your hay dry properly—and that all starts with a tight-fitting pivot pin.
Made to Last
The constant back-and-forth motion of a mower puts serious stress on every pivot point, especially the knifehead pins. This replacement is built to handle thousands of cutting cycles and the inevitable dirt, debris, and moisture that comes with field work. The grease fitting means you can keep things lubricated between seasons, which is what makes the difference between a pin lasting one season or five.
Good to Know
When you’re swapping this pin, it’s a perfect time to check the condition of your knife sections and guards—worn pins often go hand-in-hand with other wear items. A little grease on installation helps everything go together smoothly, and don’t forget to give that zerk fitting a pump or two before you head back out to the field.
