<P>PROBLEM TO BE SOLVED: To improve the effect of a brake in high load travel, in a working device having a hydrostatic continuously variable transmission. Ž<P>SOLUTION: The working vehicle has the hydrostatic continuously variable transmission 22, advancing-retreating pedals 14 and 15 and brake pedals 31 and 32. and is constituted so that a trunnion shaft 22c of the continuously variable transmission 22 can be shifted via an intermediate link mechanism 36 and a shift rod 38 by operation of the advancing-retreating pedals 14 and 15. The working vehicle is characterized in that the continuously variable transmission 22 is provided with a neutral return mechanism 41 with a return spring 44 for returning the trunnion shaft 22c to a neutral position when the advancing-retreating pedals 14 and 15 are not operated, and a part between the return spring 44 and the brake pedals 31 and 32 is connected via tension strengthening means 42 and 43 for strengthening tension of the return spring 44 in relation to stepping of a brake.
