Yardworks 21” FWD (front wheel drive) self-propelled mulching lawn mower for sale. $350 FIRM. This is a MEDIUM-DUTY lawnmower with Kohler XT675 149cc AutoChoke engine (comparable to a Honda), so it will handle standard sized residential lawns with ease. This mower is FWD self-propelled (which is more like a power assist compared to a RWD version), has autochoke (so just pull the chord and the engine starts), and can mulch with the mulching blade and integrated mulch-plug or be used with the included grass bag. I am a small engine mechanic and have fully serviced this mower: -new spark plug -clean air filter -new engine oil -carburetor has been disassembled and serviced -mulching blade has been sharpened, balanced, and oiled -self-propulsion belt and function has been tested -has been inspected and power-washed -90day no-start warranty
