I have a musgrave 60623 with a clinton engine . Can you tell me how to find info on it?

Hey Bob, try this site and scroll down to the abtract. Seems Orly Musgrave has not done much since 1970 so don't expect to find parts too easily. INDEPENDENTLY OPERABLE DUAL DRIVE WHEEL RIDING POWER MOWER - Patent 3702051 Good luck on your quest your friend Bob
