ABSTRACT:
The invention provides a portable towing device for downhill or water skiers which includes a drive unit. This drive unit comprises a motor and a drive pulley connected to the motor by a rotor which is rotated by the motor. The motor has an actuator which is movable from an idle position wherein the motor idles to an increased power position wherein the power output of the motor is increased. A first anchor is used to anchor the drive unit in the ground in a stationary position. There is also second anchor which is engageable in the ground at a distance from the drive unit and which has a support pulley connected thereto. An endless cable extends between and is entrained about the drive pulley and the support pulley and has an upper portion and a lower portion. A switch comprising a linkage is rotatably connected to the actuator at one end and to the cable at the other end by a regulator roller. This switch is operable to move the actuator to the idle position when the tension of each of the portions of the cable on the regulator roller are equal and to move the actuator to the increased power position when the tension of the portions of the cable are unequal.
