High-Performance Knifeheads for Sickle Mowers & Hay Equipment
The knifehead is the heart of your cutterbar’s motion, transferring power from the drive system to your sickle sections. If your mower is vibrating excessively, cutting unevenly, or making unusual noises, a worn or damaged knifehead could be the reason. Cutting Components offers replacement knifeheads engineered for strength, precision, and longevity in the field.
Our knifeheads are built to OEM specifications—or better—and designed to fit popular models from John Deere, New Holland, Massey Ferguson, Hesston, Case IH, and more. Each unit is precision-machined and balanced to reduce wear, minimize vibration, and improve cutting efficiency. They're ideal for both rebuilds and preventive maintenance.
Trusted by farmers, restoration professionals, and equipment dealers across the U.S. and Canada, our knifeheads are made to last through rugged conditions and long cutting seasons. Whether you’re doing routine maintenance or field repairs, we make it easy to find the right part for your machine.
