Best pull behind core aerator

[TractorDale]

Can anyone recommend a good brand of core aerator that is heavy duty and well-built. I will pull behind a JD X700 series garden tractor.

Thanks!

Tralee, I used mine today, its a Brinley and I weigh it with two 8 x 8 x 16 cement blocks. It just does not penetrate like a powered one will. I may even rent one as I am trying to rehab my lawn this year.
