When your Massey Ferguson starts slipping under load or you're grinding gears during shifts, the clutch disc is usually telling you it's time for a replacement. This 12-inch organic-faced disc is what transfers power from your engine to the transmission, and when it's worn out, your tractor just can't do the work you need it to do. A fresh disc gets you back to smooth engagement and reliable power transfer.

Whether you're running a 230 for lighter duty work or pushing a 390 through heavy tillage, this disc handles the power transfer that keeps you moving. These are the tractors you see doing everything from hay production to loader work on farms across the country.

Installation Notes This is a main drive disc, so you'll need to split the tractor to get to it - typically a job for someone with clutch experience. The 1-1/8 inch x 21 spline configuration is standard for these models. A good tip: always check your pressure plate and release bearing while you're in there, since clutch problems rarely happen in isolation.
