A replacement engine kit for Walker MTGHS mowers built around the Kohler Command CH740 V-twin. It is aimed at owners doing a like-for-like engine swap rather than a rebuild. The CH740 is a proven 25 hp air-cooled V-twin with hydraulic lifters and a full-pressure lubrication system, so it runs smoother and needs less valve maintenance than flathead or solid-lifter engines. The trade-off is that this is a fitment-specific kit: confirm your mower's spec and engine mounting before buying, since generic CH740 engines vary in crankshaft, exhaust and wiring details.
