If you want a high quality lawn aerator, there is a lot that you should know. First of all, you want and aerator with a Honda engine on it. Honda engine will last about three times longer than a Briggs & Stratton. Even though they can cost three or $400 more, they are definitely worth it. Another thing to look for when you buy and aerator is how well you can maneuver it. I think that a Ryan for is one of the better aerators as far as maneuvering and control goes. A Billy goat aerator is very well built except for the fact that it is difficult to maneuver. Another thing you want to look at is to read customer reviews about different kinds of lawn aerators. Some of them are better for spring aeration and some of them will aerate just fine in the fall.
The other thing you want to look at is the quality of the aerator. I am not sure if all bluebirds are low quality, but the one that I owned for three years was the worst aerator I ever had. I had to constantly repair it and spend more time on available because of small parts breaking on it than I did actually using the machine.
The type of machine you get isn’t pour into the quality of the aeration that you will be able to do. In order to get better plugs when you aerate a lawn, you want to make sure to always water the lawn well the night before, and you want to make sure that the machine has all of its weights in it. The weights, and the wetness of the soil will determine how far your aerator will go into it. Ideally, you want to get a 2 inch plug when you aerate your lawn.
