Description
When you’re cutting hay with your New Holland 451 or 456 disc mower, a sharp, well-maintained sickle knife makes all the difference between clean cuts and ragged stems that dry poorly. This riveted 9-foot sickle assembly comes with 34 individual cutting sections already installed, so you can get back to cutting without spending hours riveting sections one by one.
What You’re Getting
- Complete 9-foot knife with 34 pre-installed sections – no assembly required
- Extra coarse 7-tooth serrated sections that slice through thick, tough hay stems
- Top serrated design that grabs and cuts cleanly rather than just bending stems over
- Riveted construction that’s proven to handle the vibration and impact of disc mower work
Built for Real Farm Work
This knife fits New Holland 451 and 456 disc mowers equipped with double guards. These mowers are popular choices for hay operations because they handle everything from first cutting alfalfa to heavy grass fields. The extra coarse 7-tooth sections are specifically designed for cutting thicker, more mature hay crops that would dull finer-toothed sections quickly.
Made to Last
The riveted construction holds up better than bolted knives in the tough conditions of hay cutting. Each section is properly positioned and secured, so you won’t have individual sections coming loose during operation. The top serrated design keeps cutting efficiently even as the sections see normal wear from rocks and debris.
Installation Notes
This is a direct replacement for your original knife – it mounts using the existing hardware and doesn’t require any modifications. When installing, make sure the knife bar is properly supported and check that all mounting bolts are tight. A good tip is to keep a few spare individual sections on hand for field repairs if you hit something unexpected.
