I havent gotten into doing this kind of stuff on big scales, but since it's my old school, i figured I'll at least look at it. Met with someone and we came to the conclusion that it needs to be dethatched, aerated and then overseeded. Is there a bigger aerater and dethatcher that i can rent to do big jobs like this? The size of the field is 110 yards by 64 yards. What would be the going rate something like this?? Thanks in advance.
