Having trouble mulching my lawn?

well you are trying to mulch to early in the morning or to late in the evening. best time to do it is about 3 or 4 pm, when it is driest.may also want try cutting the yard more often like every 4 days instead of every 7 days. it wont be so tall and the mower wont have to work so hard to cut it.in order to keep gr from sticking to the bottom of your deck, clean it out and soak it down with wd-40. as for the dents and dings in your blade sharpen it or have it done for you at local hardware store. good luck mate
