I am a MDD owner and was considering looking for a used 42" mulching deck new style. I know nothing about them. My experience with mulching is clumping and clogging but I never tried it on a mower like this. Does the deck actually work. I hate to spend all the money and have it not work for me. Any help from those who have used them would be a appreciated. Do they mulch even in the heavy thick growing season? Thanks in advance.
