Ego should create an aerator. I am tired of renting these heavy aerators form Home Depot. A nice light weight aerator would be a welcome addition to my Ego line of products. Please make this happen.
I tried using a de-thatching blade on my mower. Had to recharge the 7.5 amp battery 5 times to do 500 square feet of lawn. Not a good idea. as for aerating, that is not a widely sought after tool. So, I doubt that will happen. Of course they make snow blowers that I have no need of so who knows.
Aerating is tough business. Trying to pull plugs in very hard SC soil is difficult work and even when I had a riding mower, I had to put 75+ lbs on my pull behind aerator to get it to sink in enough. It's an awesome idea but I don't know if the battery power would hold up to this.
