I've only powerraked about 500 yards so I probably don't know what I'm doing by now, atleas thats what people seem to think. Yesterday first lady comes outside and says her husband use to powerrake their yard 2 or 3 times when he rented one. I said just because he did it that way doesn't mean its the right way. She haggles on the price and I settled on a low price and she ended up handing me chech for $10 less than what we agreed on. Next guy says when he used rent one he would lower it until dirt was flying and tearing out 80% of the lawn. I was like what good could that result in, you may as well hire someone to Harleyrake it. You are supposed remove dead thatch, not all of the lawn. Some guy I powerraked for last whined about the price but called and wanted it done today, then he calls this morning and says to cancel because since he bags when he mows there is no dead thatch. Hello people, dead thatch has nothing to do with bagging when you cut. It has everything to do with the way you fertalize and water(TOO MUCH).
