Ideal for yards up to 1/2 acre, the 23-in. Rear-Wheel-Drive Self-Propelled Lawn Mower with Pace-Control System automatically adjusts the mower pace to your walking speed while the rear wheel drive delivers added traction and control on flat, hilly, and uneven terrain. It features a 196cc CRAFTSMAN® engine to deliver maximum performance. A 3-in-1 deck allows you to discharge (rear discharge sold separately), mulch to help put nutrients back in your soil for a healthy lawn, or use the 3.1-bushel Dust Blocker™ bag for easy cleanup or composting while reducing in-air dust and debris. The dual-lever, 6-position height adjustment makes it easy for you to change the cutting height while mowing.
