Hello all, Am looking at buying an old Bobat (1972-1982) production years. It is belt driven but has hydros for the business part. Looks to be in decent shape, runs and works, but needs some work, good paint (repainted at one point). Just looking at it for fartin' around in the garden and small house projects. What would you pay for a unit like this? Were these units decent for their time? Do ya think I'd be buying a bag of problems? Any known problem getting parts for a unit this old?
