I have been working for the a small commercial lawn care business for about 8 years now and the entire time we have been bagging grass. Now I know there has to be a better way in terms of mulchers, but what is it? We currently use all John Deere riding mowers (475, 485, 495) is there any custom mulcher decks that we could purchase or is it the whole mower system (preferably a deck width of 54 - 60 in)? What type of horsepower do we need to effectively mulch the grass (Gas or deisel better)? Also to mulch grass with out leaving trails how fast should the blade tip speed be? Sorry for so many questions but I know I can get some helpful insight to answer some of my questions. I am sick of bagging grass and I know there has to be a beter way!
