I take it you got an old Massey TE-20. They are great little tractors pretty much a carbon copy of the Ford 8n or you could say Ford copied the Massey for the ferguson 3 point system. Regardless they are great little tractors when used within there limitations. The Perkins motor inside them is a strong motor with parts still pretty readily available.
The only thing bad I have heard about the Massey's is that the Perkins diesel in them can be a bear to start in colder weather but once going they run great.
