This 21-in. self-propelled mower is ideal for medium-sized yards. It has a 163cc Briggs & Stratton® engine with one step starting, no priming needed. The mower's vertical storage technology can reduce your storage space by over 70%. Mow at your own pace using the single lever speed control. The 3-in-1 deck allows you to mulch, helping to put nutrients back in the soil for a healthier lawn, discharge or use the 1.9 bushel Dust Blocker bag for easy cleanup or composting. The 8-in. front and rear wheels provide improved maneuverability on any terrain and the dual-lever, 6-position height adjustment makes it easy for you to change the cutting height while mowing.
