Just put on a set of double blades. Have to say i am not very impressed. I do not think it stripes better at all. I loose too much horsepower when going up hill, and i have a 25 hp kohler, and it is a little loud. The only good place to use them is in my dad's pasture mowing tall grass, it really chops tall grass down but still use too much power and not to mention the fuel use. I do not recommend double blades, just not worth it. Just my opinion.
