Im looking at the 36" Metro and am wondering whats better between these two motors. Id like to go with the Kawa since it seems like a better brand, but is the 12.5 underpowered for the 36" metro with velke? One Dealer prefers the 15 hp for power, but another one prefers the Kawa since its specs are better than the Kohler. Also, I was talked out of the 36" metro hp, dealer said with such a small deck, the floating option wasnt that beneficial. This mower is for home use only, so it wont be used everyday. Also, any benefits of the ECS over the Pistol Grip?
