Aeration, Aerovator, difference, price, when , walk behind, towbehind?

[syzer]

I was checking the archives, and have'nt been able to find a direct answer to some of these ?'s. What is the difference between an aerator and an aerovator? Which do you guys prefer tow behind or a walk behind, i assume a zt cant tow one behind. Am I wrong? What is a good price to get one of these units at for just starting, what times of year do i do this what are the advantages? I assume this goes hand and hand with fert and over seeding? What is the process i should go about this, adnis there a FAQ or somethign i can learn more about this. I want to be able to offer this to my customers from the start.

Thanks....

You should find all these answers except for the prices. I have a Ryan 28 paid $2300, it's a walk behind. The 60" Aera-Vator cost around $4300.
