PROBLEM TO BE SOLVED: To provide a transmission mechanism of a work vehicle such as a rice planting machine which is provided with a seedling placing platform and a seedling planting pawl and continuously performs a seedling planting operation, a tractor, a combine or construction equipment.SOLUTION: A work vehicle includes a transmission mechanism having a hydraulic transmission mechanism 57 to which constant speed power is input from an engine and a planetary gear mechanism 83 which combines the constant speed power from the engine with variable power from the hydraulic transmission mechanism and outputs the combined power. The planetary gear mechanism is configured such that the rotation direction of combined output is unidirectional and, as the variable power is changed from a reverse rotation into a normal rotation via zero, the unidirectional rotation speed of combined output increases and the combined output has a unidirectional prescribed rotation speed when the variable power is zero. |
