It still has mulching, discharge and bagging capabilities, though the bag must be purchased separately, and there is an optional side chute accessory as well. The increased motor power means that the MM575 is more suitable for dense lawns or lawns that require heavier mulching. It is recommended that the maximum distance from an electrical outlet be no more than 100', since the MM575 must still be plugged in to run. It has a cutting height range of 1" to 3.5" and this can be adjusted with a single button. The deck width is 18" and made of plastic polymers, meaning that the mower is relatively lightweight. The deck has a lifetime warranty and the rest of the mower has a 2 year warranty.
