Our farm is selling a 977 we have had since 1963, this has been a great machine. The ring gear in the steering clutch group popped, I sourced a replacement part for $675 from Smart parts of Alban Cat, but we decided to buy a used 963. Engine in this runs great, we put a 24 volt starter drive in a few years back with updated wiring and good gauges.
