How Deep Can a Tractor Auger Dig?

Tractor post hole diggers are limited to how deep they can dig by the length of your bit.  Same goes for a regular post hole auger.  

Most tractor auger bits let you drill down about 3 feet, which is the perfect depth to cement in a fence post.  If you’re using your auger bits to drill footings for decks or other structures, you’ll be needing a bit that can drill down to 6 feet.  

Some tractor diggers will include an extension rod so you can drill down that low.  Otherwise, you should also purchase an extension rod.

How deep can a tractor auger did depends on the length of the standard bit it comes with and whether or not you have an extension rod.
