The last year the 14SB was produced was 1997, which makes that mower at least 24 years old, could be even older. There were two different units made, one with a splash lube system and the other with a pressurized lube system. With a unit that old you might get 2 cuttings or 10 years out of it. I wouldn’t take that gamble on any mower at that price, but it is your dollar and maybe you are a gambler.
