Abstract

PURPOSE: To make it possible to drive at ultra low speed and at the same time to switch from forward driving to backward driving and vice versa instantly by the method wherein, in the titled device in which an oil pressure drive device is provided in addition to a gear speed change device, a differential deceleration gear mechanism is provided for the oil pressure drive device, and it is so constructed that the differential function of the differential mechanism can be stopped.
CONSTITUTION: When a tractor is driven by the instant forward-backward switching mechanism, set the main speed change lever neutral and engage slide gear 40 with gear 37 by means of the selection lever. When motor 12 is driven under this condition, gear 45 and casing 42 rotate at the same speed in the same direction. By this, the differential function of the differential deceleration gear mechanism 47 is stopped, planet gear 43 revolves without rotating, and thereby power transmission shaft 39 is rotated via gears 43b, 46 and 49. When the oil pressure direction control valve is switched by the forward-backward switching lever, oil pressure motor 12 rotates in the opposite direction, and as a result, power transmission shaft 39 also rotates in the opposite direction and the tractor travels in the opposite direction.
