I have two donated treadmill motors and controllers and wonder if one could be for a clockwise rotation and the other for a counter clockwise? I am told too that my soil should be clay to sand also. Easy drilling I hope.

Most of the reports stoped after they hit the aquifer so I don't know about beyond that. But they don't mention an actual rock layer. As for the motor, it's DC so just put in a switch to swap the polarity to the motor and same motor spins both directions
