Description
When you’re out cutting hay and that sickle bar starts leaving uncut stems or pulling instead of slicing clean, it’s time for a new knife. There’s nothing worse than a dull cutting system when the weather window is tight. This complete 7-foot riveted knife gets your Case IH 100 balanced head, Ford 505, or New Idea 521/522 mower back to cutting like it should.
What You’re Getting
- Fine tooth under-serration at 14 teeth per inch cuts through thick stems and tough grasses without clogging
- 27 individual riveted sections that stay sharp longer than bolted knives because they don’t work loose
- Factory-correct knife head design fits existing guards and wear plates without modifications
- Under-serrated cutting edge grabs material and pulls it into the cutting action for cleaner cuts
- Heavy-duty construction that stands up to rocks, fence posts, and other field hazards
Built for Real Farm Work
This knife fits the reliable mowers that have been cutting hay for decades – machines you’ll find on dairy farms, beef operations, and custom hay crews from coast to coast. Whether you’re cutting first-crop alfalfa, mixed grass hay, or cleaning up roadside ditches, these mowers handle the job when paired with a sharp knife.
Made to Last
The riveted sections feature a black finish that resists corrosion and maintains cutting performance in wet conditions. Each section is hardened to hold its edge through thousands of acres while the riveted construction keeps sections tight to the knife back, preventing the wobbling that dulls cutting edges prematurely.
Installation Notes
This is a direct replacement for your worn knife – no modifications needed. Before installing, check your guards and wear plates for damage that could cause premature dulling. If you’re working on a Case IH 100 balanced head, consider checking the knifehead pins and bushings while you’ve got things apart. A sharp knife on a tight-running head makes all the difference in cutting quality.
