This machine combines true 30″ wide aeration and speed up to 4.3 mph to complete 1/4 acre in as little as 15 minutes! That’s 59% faster than a 26″ drum! Plus no more lifting on turns; aerate in reverse; do trim and edges with ease; and significantly improve hole quantity and quality vs. drum aerators.The AE1300H features Patent Pending variable aeration density (VAD^™) and creates 2-10 times more holes than drum models in one pass (8-48 holes per sq. ft.) This eliminates double or triple aerating typical with drum aerators that have fixed hole patterns as low as 4 per sq. ft. and saves significant time. VAD also offers ability to do patch repair and seed bed prep in one pass by simply slowing down over bare spots.
