aerator

I'm thinking about purchasing an aerator. I have a 6 acre lot with grass and trees. It's decent grass, but it is not smooth pasture land. A drum seems heavy duty, but I wonder if that solid steel would be a negative on land that isn't completely flat. There are other companies that have spoons...

Anyone have experience with an aera-vator, made by 1st products ? Saw a used one for sale and was interested for general lawn aerating as well as possible overseeding, but this is the first I’ve ever seen one. Would be used in multiple soil types including clay and sandy….

Will a New Holland TS110 pull a 12 spike aerator, my ground is pretty hard dirt. i don’t reallly need a 12’ but there is a used one with a real good price on it with the weight blocks already on it.
