HUSQVARNA 21” RWD (rear wheel drive) Self-propelled lawnmower w/ blade-stop for sale. This is a Medium-duty lawnmower with a powerful HONDA 160cc engine, so it will handle standard to large sized residential lawns with ease. This mower is RWD self-propelled so it has a lot more power and traction than a FWD mower, it can mulch grass with the included mulch-plug or be used with the grass bag, it has the blade-stop feature so the engine can run without the blade spinning for quick bag emptying or use of the self-propulsion to move the mower, and it has a single lever height adjustment feature. I am a small engine mechanic and have fully serviced this mower: -new spark plug -new air filter -new engine oil -new carburetor -blade has been sharpened and oiled -self-propulsion function has been tested -has been inspected and power-washed -90day no-start warranty
