Inherited an old Wizard Western Auto rototiller from the 70s.
It does work. But how does one go about lubricating the lower unit?
Has no zert fittings but I did find what I did take to be the
equivalent of an oil fill screw. Is this one of those things that is
usually filled at the factory, sealed, and usually you don't have to
worry about it again? Or is it something that you're supposed to check
each season? And if the latter is the case what type of oil or
lubrication would you use for something like this?
