I like the fine height control the operator has of the driver at the end, to get it just right.

guy in background seems to be checking one that is not plumb

Looks something like the driver they used for the piles under our new house. I expected it to be automatic but an operator controlled the up/down travel by hand. That has got to be a long day!
