Any thoughts on whether it's a good idea to mow and aerate at same time? I have a pull be hind plug aerator for my mower, but my mower is old/cheap and I don't want to overwork it (by running the blades and towing the aerator with cinderblocks).

But it would save me the step of mowing and then aerating. Also, maybe it's good to get the mulched up grass down into the holes?

Thoughts on this?
