David started a thread recently about his new walk behind aerator. As good as the video was, the actual unit is even better. David was passing by today and stopped in to let me do a quick demo. In a word - fantastic! This unit is incredibly easy to use and very nimble. I have a Turfo Turnaer, which is a fine unit, but this will run circles around it. Excellent going across a slope, true hydro drive, simple and built for heavy use. If you like the Lawn Solution seeder, you'll love this unit. And the best part is the unbeatable price.
