I just cut the grass for the first time with my new MFT with the mulch kit this past Sunday and was just covered with leaves, dust, and debris. I ordered the blow out kit first thing Monday morning, but wanted to hear from anyone who's installed this "option" to see how well they really work. What percent reduction in blow out might I reasonably expect? Thanks. PS. I posted this on the homeowner's forum, but haven't gotten any responses.
