It's the Specially Designed Steel Tines that do all the digging.
Any Shop Vac simply sucks up loose dirt.
Here's how it works:
Attach Bull Digger to any portable, full-size shop vacuum.
Turn the shop vac on and start digging.
The chiseled steel tines break up the soil and make digging easy.
As you dig the shop vac sucks up the loose soil into the bin.
No more messy dirt piles.
The soil is now ready for easy backfilling.
