Hello, Bought a 17 hp briggs, craftsman mower real cheap, just to get me by until I get My Tiger cub next season, and this is the most awful mower I have ever seen. Not only do i have a new engine leak, the mower is cutting like garbage. No way i can mulch with it, leaves huge paths of clumped grass, when I take mulch cover off it leaves a huge path of cut grass. My friend has a Scott's that mows very well leaving no path of grass, and can mulch very well also. Doesn't seem to matter if I have new blades or not. I was wondering if maybe my rpm's are too low and not chopping the grass up enough,.. I don't know, Anyone else have this problem?
