This 21-in self-propelled, variable-speed front wheel drive is ideal for smaller yards and allows you to mow at your own pace. Its 163cc Briggs and Stratton engine features one-step starting, no priming needed.. A 3-in-1 deck allows you to discharge, mulch to help put nutrients back in your soil for a healthier lawn, or use the 1.9 bushel Dust Blocker bag for easy clean up or composting while reducing in-air dust and debris. The 11-in 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.
