I'm looking into adding an core aerator to my arsenal. I am a solo operator, so easy to use and use for a long time is a big plus. I am looking at the ride on's by clausen and lawn solutions, but not sure if I can justify the cost. Think I could get a ton of aerations done and even really push new aerations if I had one of those. Any thoughts on the ride on's? What about split drive? Are they as easy to turn and use as the videos? What brands to look at or stay away from?
