Replacement 12v. starter for all Hercules IX-series equipped machines:
Cletrac HG, Oliver-Cletrac HG, Oliver HG, Oliver OC-3, 4 cylinder Oliver OC-4 and OC-46.
 
Also: Cletrac General GG, Avery A, Wards Twin Row, Minneapolis Moline Model BF, Silver King or indeed any machine with a Hercules, IXA-3, IXK-3 or IXB-3 engine - combines, generators, forklifts etc.
 
This is a modern 12v. gear reduction starter modified to fit these engines.
The 'gear reduction' means it spins at the same speed as the original 6v. starter for the most effective start.

If you use an original 6v. starter with a 12v. battery it turns the starter twice as fast which can cause the starter to fail and will sometimes spin the magneto too fast to initiate an impulse.
 
Hundereds sold and no complaints!
