This unit is considered a one man unit and the auger is driven hydraulically. Benefits of this machine is safety and power to run through the hardest ground. That said we have a few rocks in our area and they cause issues with success. Wise to have a 5′ crow bar on hand to get those pesky ground knots out of the way. They come with a tow bar that hooks to a 2″ ball and we have augers from 6-12″ and you can get down 4′ with use of an extension.
