Hi there, i'm looking at purchasing a used but in good condition tow behind Cushman GA60 aerator. (also made by ryan??) http://www.gardenequipmentreview.co...equipment/turf-care/aerators/ga60ga60-pt.aspx. I'll be using it for condo complexes in open areas. it's built for fairways.. anyone here have any expierience with these machines? it's selling for only $1800 canadian . which is an incredible price if i can use it. the only problems i can come up with is if it's build for fairways, what might happen if i hit a rock or root under the soil.., and also i was considering pulling it with a quad, and it needs hydraulic lines to lift so i'd need a hand pump or something. please any input would be greatly appreciated, thankyou.
