We would have the commercial grasshoppers buying the Toro's the four cycle heavy iron. They would buy fertilizer, lime, fescue and bluegrass, antifungual etc.
My dad's friend, he finally gave a lawnboy a try. It sure was expensive then the regular fours and it made funny high RPM sounds... Years later he did admit that the lawnboy while 60% premium over the other mowers, it sure did outlast 3-4 of them other ones.
