Craftsman 21” FWD (front wheel drive) self-propelled mulching lawn mower for sale. $400 FIRM. This is a medium-duty lawnmower with a powerful Kohler XT-7 173cc auto-choke engine, so it will handle standard sized residential lawns with ease. It starts on the first pull (no priming or choke settings are necessary), and is FWD self-propelled so it will assist with most of the pushing force needed to move the mower forward. This mower can mulch grass with the installed mulching blade and integrated mulch plug, or be used with the included grass bag. This mower has been fully tuned-up and is in great condition. I am a small engine mechanic and have fully serviced this mower: -new spark plug -new air filter -new engine oil -carburetor has been disassembled and serviced -mulching blade has been sharpened and oiled -self-propulsion belt and function has been tested -has been inspected and power-washed -90day no-start warranty
