The choices that I have used are Lesco renovator, Ryan Mattaway or aerovator
Tese are all hands and feet above the the bluebitds. The Lesco unit si a bit more stable and I think easier to use then the mattaway -- especially on nay property with any hills.
My peronal faborite is to go over the yard with an aerovator.
The Aera-Vator is a 40", 60", or 80" aeration device that attaches to the PTO of a 3 cylinder tractor or they have a model that attaches to the Grass Hopper mowers, and a Dingo model. The Aera-Vator has solid tines that are attached at an angle, they are "vibrated" into the soil causing even the hardest grounds to break open.
The process I use involves applying half of the desired seed prior to running the Aera-Vator, then after apply the other half of the seed, the fertilizers, and lime if needed. The results are great, no patterns like you get with aeration or cornrows like with the Mattaway
The Aera-Vator is best on thin lawns or renovations but can be used for any lawn in place of aeration. One big bonus, when it is dry and other companies are unable to aerate due to hard ground, we continue on business as usual.
