LET YOUR LAWN BREATHE. Get your lawn in top green shape with the Sun Joe® Dethatcher Joe AJ801E 13-inch electric scarifier lawn dethatcher. Powered by a robust 12-amp motor, the Dethatcher Joe rakes a 13-inch wide path in a single pass to get your job done fast. Enhancing its raking ability is AirBoost technology, which maximizes thatch pickup with spring steel tines that stay sharp longer for reliable performance. Use the 5-position depth control knob to tailor the raking depth from -0.4 in. (10 mm below the soil) to 0.4 in. (10 mm above the soil), depending on your lawn’s scarifying or dethatching needs. Scarifying your lawn at regular intervals cuts grass roots and encourages growth for thicker, healthier turf.
