I had setup aerations to do and luckily we did get some rain. I took advice from here and went to lesco dealer to see about aerators. I rented the aerator that they had, it was a split drive unit. I was amazed at how nice it pulled the plugs out. This machine is the cadilac of all the aerators that I have rented.The weight of it made the plugging in the groud very nice! There was a neighbor that was watching me and said that the aerators that he rented never put that kind of plugs out. He asked me to bid on his lawn, I measured the lawn and gave him the rather large bid and he said that he needed to think about it. I finished up doing the job and he said he wanted me to do his lawn, as soon as I could. I had finished with all my jobs and was tired, and it was getting late,but for the money, I called him and told him I could do the aeration before dark, and do seeding the following morn. When I arrived at the house, he had a check made out and wanted to pay me, he was so impressed with the neighbors job. He now wants me to do aerations in the spring and fall, to get his lawn in shape. This was a great machine, and next year I will be adding it to my list of equiptment. I would like to know what the difference in this is compared to the clasen split drive to make my decision.
