I am looking at a Scag 26hp 61 inch deck. The dealer does not have a air cooled unit left, but has offered me the same mower, same hp, only with a liquid cooled engine, for the same price. Normally the liquid cooled is more money. Should I take it, or should I stay away from water cooled? Liquid cooled seems like more future maintenance expense even if it is the same price now. Any opinions?
