Description
There’s nothing more frustrating than a dull sickle bar slowing you down during hay season when every hour of good weather counts. Whether you’re cutting your first field or racing against an incoming storm, a sharp, properly functioning sickle knife is what keeps your New Holland mower cutting clean and fast. This riveted knife assembly brings your 451 or 456 mower back to like-new cutting performance.
What You’re Getting
- 35 under-serrated sections with fine 14-tooth-per-inch cutting edges that slice through tough hay stems cleanly
- Riveted construction that holds up better to impact than bolted assemblies when you hit rocks or stumps
- Pre-assembled 9-foot length that mounts as one complete unit—no piecing together sections
- Sharp sections ready to work right out of the box, saving you time during critical hay season
Built for Real Farm Work
This knife fits New Holland 451 and 456 mowers, machines you’ll find working on dairy farms, cattle operations, and hay producers across the country. These mowers are typically used for cutting first, second, and third crop hay, plus cutting pastures and maintaining fence lines. The riveted design handles the constant flexing and vibration these mowers experience in real field conditions.
Made to Last
The under-serrated profile and fine tooth design provide clean cuts that promote faster hay drying, while the riveted construction distributes stress better than individual bolted sections. Each section is manufactured to meet OEM specifications, so you get the same cutting performance your mower had when it was new.
Installation Notes
This is a direct replacement for worn or damaged knife assemblies. The complete 9-foot length installs as one unit, making replacement much faster than changing individual sections. Make sure your guards are in good shape before installing—worn guards will dull even new sections quickly.
