That thing made me rethink aeration.
I too went to an open house and tried it.
It was sitting there in a lineup of standers and I didn't even notice it until I focused on it for a couple of minutes.
It was the best piece of equipment on display in my opinion.
Now, one man (old/out of shape) can do the work of AT LEAST 2 PEOPLE!
I can't say enough about this machine.
Now, how it holds up will depend on other guys to post.
Remembering all my departed friends.
