Lawn-Boy 21" 2in1 electric-start self-propelled (rear-wheel-drive) mulching lawn mower for sale. This mower has a powerful Kohler XT650 149cc 6.5ft-lbs auto-choke engine that starts on the first pull (no priming or choke settings are necessary), however it also has an electric start function which will crank the engine by turning the starting ignition key. This mower is RWD self-propelled, so it has a lot more power and traction than a FWD version, and so will easily propell itself uphill. This mower can mulch grass with it's heavy-duty mulching blade, or be used with the included grass bag. This mower has been fully tuned-up and is in overall excellent conditon, and is a very high-quality mower from Lawn-Boy that that is sure to last a long time with proper maintenance.
