The planet gears of the planet assembly have inner and outer portions that rotate together and have different diameters and different numbers of teeth, one ring gear engaged with an inner portion and a second ring gear engaged with an outer portion of the planet gears. Said ring gears matched to the respective planet gear portions and having different numbers of teeth and different diameters as required to achieve involute engagement of the ring gears and planet gears whereby the rotatable gear is caused to rotate at a substantially reduced rate of rotation. Said rotatable ring gear is fixed to the winch reel for reduced rotation of the reel.
