PROBLEM TO BE SOLVED: To provide a miniaturized riding type self-propelled working vehicle having a structure for elevating/lowering a working part of a work unit capable of expanding a working space part during the maintenance of the working part of the work unit and enhancing the workability without changing the driving position of a worker between the working mode and the regular traveling mode. SOLUTION: The riding type self-propelled working vehicle (A) is elevated/lowered by turning a cultivation unit (C) to be turned around an axle of rear wheels (T2, T3). A seat (17) is provided above a prime mover (5). A transmission (7) for traveling is provided on the cultivation unit (C). A front wheel (T1) and the rear wheels (T2, T3) are driven by a hydraulic continuously variable transmission (8) and a hydraulic motor (M). A differential gear is provided between the rear wheels (T2, T3). COPYRIGHT: (C)2006,JPO&NCIPI
