Description

When you’re cutting hay with your New Holland windrower, a dull or damaged knife can turn a smooth operation into a frustrating day of ragged cuts and plugged guards. This replacement knife gets your machine cutting clean again with 25 extra coarse serrated sections that slice through tough stems and thick stands without hesitation. You’ll know the difference the moment you drop that header back into the crop.

What You’re Getting

  • 25 top-serrated sections with extra coarse 7-tooth design for aggressive cutting
  • Bolted construction makes replacing individual sections quick and economical
  • Left-hand configuration specifically designed for proper crop flow
  • 7-foot length matches your windrower’s cutting width perfectly
  • Direct replacement that fits without modifications or special tools

Built for Real Hay Work

This knife is engineered for New Holland 907, 909, 910, and 912 windrowers—machines that spend long days cutting everything from first-cut alfalfa to heavy grass hay. These windrowers handle the bulk of hay production on farms where speed and cut quality matter, whether you’re racing weather or trying to maintain leaf retention in premium alfalfa.

Made to Last

The extra coarse serration with 7 teeth per section tears through stemmy crops that would dull smooth blades in a hurry. Each section is built to handle the constant vibration and impact of cutting at speed, while the bolted design lets you replace just the worn sections instead of the whole knife.

Installation Notes

This knife mounts on the left side of your header and comes ready to install with no head assembly required. Keep a few extra sections on hand since rocks and stumps are part of hayfield reality, and replacing a section takes just minutes with basic hand tools.
