A couple days ago we received our new aerator. It is self propelled, aerates forward and backward, and can turn with the tines in the ground! We have had a hydrostatic overseeder made by the same company, Lawn Solutions, since 2008 and customers have been pleased with its easy controls. So far the new aerator is getting good reviews by customers; no more pulling the tines in and out of the ground! Now is the time for aerating according to the U of M Extension Service!
