For those operating 400 series models up to 700 series units and now the new 8000 series, our durability-tested parts cater to both 56" narrow body and 67" wide body designs. Whether your machine features a walker or twin rotor discharge, we provide the components you need.


unique cylinder technology
for better beater performance

The Sunnybrook Gen 2 enclosed cylinder delivers consistent feeding for both walker and dual rotor discharge machines. It further optimizes the functionality of the chevron beater in rear-mounted twin-rotor models. Featuring 32 staggered RASP bars with a highly aggressive leading edge, this design transforms our cylinder into a positive displacement 'gear pump,' setting it apart from standard OEM cylinders.

from Sunnybrook Welding

Beware of imitations. While imitation is the highest form of flattery other component manufacturers may make lofty promises, but only Sunnybrook Concave Parts possesses the components, hardware, and expertise to truly deliver on those commitments. Backed by 45 years of experience in combine component manufacturing, we stand as the acknowledged leader in pioneering harvesting technologies.


Advanced Concave Designs
Help you harvest smarter

Our concaves, available in both wide and narrow configurations, feature bolt-in, reversible/replaceable boxes in the front half, allowing you to customize performance for your crop range. We designed our concaves with not just your budget but also the environment in mind, ensuring that you don't discard 200 pounds of quality steel due to a single worn edge. We find such waste both shameful and unnecessary when our reversible Sunnybrook concave technology offers greater returns while reducing the strain on precious resources. Another distinctive feature is our ingeniously engineered center ‘V’ in the box design, enhancing the efficient diversion of material to the twin rotors, resulting in reduced friction, lower fuel consumption, higher, cleaner yields, and most of all, virtually eliminating plugging with our complement of products.


Friction is the enemy - boron is your ally

Sunnybrook Welding provides super-hardened wear kits designed to significantly prolong the service life of your Chevron Beater. Explore the advantages of our boronizing process in reducing the friction coefficient and cutting down on fuel bills. In the realm of long-term farming, the twin keys to success are durability and fuel efficiency.
