Three years ago when I was in school my uncle rented Lesco walk behind Aeator to do his yard with... His friends found out he had it and wanted there yard done so I went and got it and did it for them. These same folks approached me today and wanted it done again, and I told them if I could track down an aerator I would do it. The rental place that my uncle rented it from went out of business and I dont know where I can find one now. Should I consider buying one? I have a hitch on my mower so I thought about getting a pull type? Any help would be appreciated.
