Simplicity 552 is a high-quality tiller that can help you to prepare your garden for planting. It features a 3 H.P. Briggs & Stratton engine that provides plenty of power to turn the 12 hardened steel tines. The tines are adjustable, so you can set the tilling depth from 0 to 7 inches. The tiller also features a touch-o-matic clutch control for easy engagement and disengagement of the drive, and a handle-mounted throttle lever for easy speed control.
