Abstract
The present disclosure relates to a method for driving a ski course gate into a snow covered surface. The method includes the step of providing a portable driver having a housing, a drive member rotatedly connected to the housing, a gate engaging structure connected to the drive member, a rotational power source, and a rotational transference assembly mounted within the housing for transferring a rotational input from the rotational power source to the drive member. The method also includes the steps of inserting a pole portion of the ski course gate within a longitudinal channel of the drive member and sliding the pole portion longitudinally through the longitudinal channel of the drive member. Next, a torque transmitting engagement is formed between the gate engaging structure of the portable driving device and an auger portion of the ski course gate. Finally, the rotational power source is activated while a downward force is applied to the ski course gate such that the auger portion of the ski course gate is rotationally driven into the snow covered surface.
