Document Type and Number:
Japanese Patent JP6514958
Kind Code:
B2
Abstract:
In a work vehicle such as a tractor, efficiency of a transmission path and operability can be enhanced while lighter weight and reduced cost can be achieved. The work vehicle includes an engine 5 mounted on a traveling body 2, a straight-traveling system transmission path including a first stepless transmission device 17, and a turning system transmission path including a second stepless transmission device 13, and is configured to combine an output of the straight-traveling system transmission path and an output of the turning system transmission path to drive left and right traveling units 3. The work vehicle also includes control sections 813 and 814 that control the output of the straight-traveling system transmission path and the output of the turning system transmission path in cooperation with each other; a transmission operation tool 822 that specifies the output of the straight-traveling system transmission path; and a detector 823 that detects the output of the straight-traveling system transmission path. The control sections 813 and 814 select one of an instruction value from the transmission operation tool 822 and an actually measured value from the detector 823 and sets the output of the turning system transmission path.
