Came across this in my travels:
It really caught my attention because the price delivered is not much different than the rental I'm planning when you include the cost of the tines. With 8 rows across 64" it won't have the same density as the Deere Aerator 800's 36 holes/sqft. It looks more like 3-4 holes/sqft per pass.
It clamps on the frame so no holes are required, although they are optional. It isn't as fancy as the JRCO, but 1/4 to 1/5th the price.
They also have a spreader and dumpable hauler:
Has anyone tried the aerator?
