I just recently started mulching instead of bagging and it saves so much time. The only thing is though, I use a mulching kit or plug for my mower, JD GS30 36" WB, with a mulching blade and sometimes if the grass is kinda tall or a little wet I get all sorts of trouble. Either there will be small clumps or the bottom of the mower gets so caked with grass I don't even think it's mulching. What do you guys do? any suggestions?
