I have found a really good deal on a new kohler cv-730s as an extra replacement engine. currently I have all 25hp kohlers. The only drawback if any, this engine has no oil cooler. I know for fact that this engine came off a new but damaged scotts mower. It runs as a new should. Any real big drawbacks by not having the oil cooler. I have 2 Bobcat ZTR mowers this could fit.
