PURPOSE: A speed change device of a farm work vehicle is provided to reduce the distance between shafts by arranging a planetary gear and a shuttle device on different shaft. CONSTITUTION: A planetary gear(120) synthesizes a hydraulic output and a machinery output of a hydrostatic step-less speed change device(10). The planetary gear is composed of a sun gear, a plurality of satellite gears, a ring gear, and a driving gear. The sun gear is rotated by the machinery output. The plurality of satellite gears is geared with the sun gear. The plurality of satellite gears is inscribed to the ring gear. The driving gear is formed at the outer side of the ring gear. The planetary gear and a shuttle device(140) are arranged on different shaft. The shuttle device is driven with an output of the planetary gear. |
