Sunnybrook Welding offers durability-tested components specifically designed for Claas Lexion combine models, ranging from the 400 series up to the latest 8000 series. Whether your machine features a 56" narrow body or a 67" wide body, with walker or twin rotor discharge, our advanced parts are engineered for enhanced performance and long-lasting reliability.
unique cylinder technology
for better beater performance
Our Sunnybrook Gen 2 enclosed cylinder delivers superior feeding performance for both walker and twin rotor discharge machines. Optimized for Claas Lexion combines, the cylinder’s 32 staggered RASP bars with aggressive leading edges enhance the chevron beater’s efficiency in rear-mounted twin rotor models. This advanced design transforms the cylinder into a high-efficiency positive displacement ‘gear pump,’ setting it apart from traditional OEM cylinders.

Advanced Concave Designs
Help you harvest smarter
Our Sunnybrook concave systems, available for both wide and narrow configurations, feature bolt-in, reversible and replaceable boxes in the front half. This allows you to adjust performance based on your crop type, providing greater flexibility and longer-lasting components. Designed with both cost-efficiency and sustainability in mind, our reversible concaves prevent unnecessary waste, helping you avoid discarding quality steel due to wear on a single edge.
- Reduced friction for better material flow to the twin rotors.
- Lower fuel consumption for greater operational savings.
- Cleaner grain yields with virtually no plugging, ensuring more efficient harvesting.
The center ‘V’ design in our concaves helps to efficiently divert material into the rotors, reducing friction and improving power efficiency, resulting in higher yields and cleaner crops.
Friction is the enemy - boron is your ally
Sunnybrook Welding offers super-hardened wear kits designed to extend the life of your Chevron Beater. Our boronizing process reduces friction, helping to cut down on fuel consumption. Durability and fuel efficiency are the keys to long-term success in farming, and Sunnybrook Welding is here to provide the combine components that make that possible.
Custom Hardened combine Components designed to your exact needs
Sunnybrook Welding specializes in custom-hardened combine components that are tailored to your specific equipment and operational requirements. Our parts are built for Claas Lexion combines and other major models, delivering superior durability and performance to help you harvest smarter.
