the gear ratio on the gear box is 3.6 to 1. it slows down the auger but add double the torque so you can run 8 or 10 inch augers on it. if running a 10 inch from a power auger you will need the clam/kdrill adapter as this allows an auger from a gas auger to be used. if running an 8 inch just make sure it is an 8 inch hand auger or you would need the adapter too.
