This 12-volt, 60-amp alternator is a complete replacement unit built to the output and mounting specification of the original equipment fitted to John Deere and Kubota tractors. It is manufactured by Mitsubishi, the original supplier for this application.
It is supplied complete with a single-groove V-belt pulley (73mm outside diameter), matching the factory setup exactly. Each unit is tested for correct output and rotation before it is dispatched.
