    摘要: The planetary drive structure includes a variable speed transmission by which the drive structure speed is universally variable in both forward and reverse directions. The drive structure also includes selectively engageable power takeoff structure. The variable speed feature of the transmission is effected by means of a sun gear and a ring gear having planet gears positioned therebetween and means for varying the resistance to rotation of the sun gear. The means for varying the resistance to rotation of the sun gear may be hydraulically or electrically energized and includes selectively operable accessory drive structure. The method of the invention includes the step of varying the speed of a hydraulic transmission in planetary drive structure in both forward and reverse directions substantially universally over the range of speeds thereof, selectively actuating accessories through the variable speed transmission and selectively actuating power takeoff means with the planetary drive structure.
