My impression of a woven clutch is one that is made similar to the asbestos fibers found in original equipment clutches until the “metallic” button clutches came out in the 60’s. I don’t know what tractor you are working on, or what type of work, but my experiences on 560’s 966’s and 1486’s is that if you can possibly get a woven material on a clutch you are better off. The newer “metallic” or “button” clutches were developed to handle the higher horse power and dissipate heat better. They did this at the expense of flywheels, pressure plates, and contributed to the need for transmission brakes in the later tractors. From my experience, you can replace a woven clutch disc several times without having to turn the flywheel or replace the pressure plate, but when you replace a button clutch, you have to machine or replace the pressure plate and flywheel every time. Combine that with the aggravation that they cause as they wear and get sticky and awfully hard to shift. If you are not in to tractor pulling and have the pressure plate springs up to spec, use a clutch properly, the woven clutches will perform very well. If you “ride” the clutch, or slip it a lot when you start out, the button clutch will last longer, but cost more to fix. My nickel.
