Air Spading direction?

[Ea Quinn]

Hello everyone,
I did a search on your website but didnt come up with anything. I was looking to get some information on air spading and seem to be coming up empty handed. does anybody have any good links on some reading so i can learn some more about the process. I did an internship with the brickman group about 6 years ago, and they had just done some air spading on a large chesnut tree, and i learned a little bit about the process, but could use some more information. thanks in advance.

Bartlett actually copyrighted their spec. for air spading......... hit their web site or give one of their local reps a call.
