 Re: Air-spade
Here in the states there are a few air spades around but not that many.
They have their place in spite of their expense. Only part of the cost is the tool. The far larger cost is the compressor. You really have to have this thing working all of the time to make it worth while. Sometimes people will calculate the cost into one large job and then rent a compressor for additional smaller job as needed.
Great tool for root collar investigations, compacted soil remediation, and vertical mulching.
Just be sure to wear hearing protection. Buy the best you can get. Look for protection with a 30dB rating. Over the ear being preferable to ear plugs.
