Description
When your sickle bar starts leaving uncut grass or starts vibrating more than usual, it’s time for a fresh knife assembly. This 9-foot riveted sickle knife is built to handle tough hay and grass conditions with its top-serrated extra coarse 7-tooth sections that bite through thick stems and matted grass like they should. You’ll notice the difference in cutting quality right away when you get back to the field.

- Top-serrated extra coarse 7-tooth saber tooth sections that stay sharp longer
- Riveted construction that holds up better than bolted knives under heavy use
- Direct replacement design that fits without modifications or adapters
- Factory-quality materials and tolerances for reliable cutting performance
Built for Real Farm Work
This knife fits Case IH 100 series balanced head mowers, plus Ford 505 and New Idea 521 and 522 units. These are the workhorses you see cutting hay fields, pastures, and roadside ditches where a clean, consistent cut matters. Whether you’re a dairy farmer putting up first cutting or a custom operator handling multiple farms, this knife handles the daily grind of commercial hay production.
Made to Last
The riveted construction means the sections won’t work loose like bolted assemblies can after hours of vibration and impact. The extra coarse serration profile cuts through thick, mature grass and light brush that would bog down finer-tooth sections. Heat-treated steel sections maintain their edge longer, so you’re not constantly stopping to file or replace worn cutting surfaces.
Good to Know
Installation is straightforward if you’ve done knife work before – just make sure your knife head and guards are in good shape before installing the new assembly. A dull or damaged knife head will wear out even the best sections prematurely. Keep a few spare sections on hand since the outer ends take the most abuse from rocks and fence posts.
