Description
When your Summers Super Coulter Plus or VTI disc implement starts acting up—maybe wobbling through the field or making grinding noises—there’s a good chance the trunnion bearing assembly is wearing out. This assembly takes a tremendous beating as it supports the disc gang while cutting through crop residue, and once it starts failing, you’ll notice uneven tillage and higher fuel consumption.
What You’re Getting
- Complete housing and bearing assembly designed for 2-inch round axles
- Heavy-duty construction built to handle the demanding loads of disc operations
- Direct replacement for worn assemblies on Summers and VTI equipment manufactured before Fall 2016
- Precise fit that eliminates the wobble and restores smooth operation
Built for Real Farm Work
This assembly fits Summers Super Coulter Plus and VTI disc implements that were built before Fall 2016. These tools are workhorses for incorporating residue, preparing seedbeds, and handling the tough conditions that come with modern farming. Whether you’re cutting through corn stalks in the fall or working heavy clay soils in spring, this bearing assembly needs to handle serious stress.
Made to Last
Farm work means dealing with mud, dust, moisture, and heavy loads that can quickly destroy inferior bearings. This assembly uses quality bearings that are properly manufactured to handle the demanding conditions of agricultural use. The housing is built to resist the flexing and stress that cause premature failure.
Installation Notes
While you have the gang apart, inspect all bearings on that shaft—they typically wear at similar rates, and replacing just one often means you’ll be back under there next season. Pack the bearing with quality disc bearing grease, not general purpose. The replacement bearing for this assembly is SMA8K2000 if you need just the bearing component.
