I have a TZ22DA w/ a 60"MMM coming. It has a side discharge and I asked about a mulching kit. I was quoted around $450 by 2 dealers and was told it consisted of baffles and a discharge cover. That seems kinda high to me. Does anyone have experience w/ this kit? The other options are a $1900 bagger or buying a $200-$300 lawn sweeper to tow behind.
