Abstract
A working vehicle includes a PTO shaft to extract power of a prime mover to an outside, a first PTO transmission shaft to receive power from the prime mover, a second PTO transmission shaft to transmit power to the PTO shaft, a first gear train and a second gear train to transmit power from the first PTO transmission shaft to the second PTO transmission shaft, and a synchromesh switching mechanism to switch power transmission from the first PTO transmission shaft to the second PTO transmission shaft between a first mode where the power transmission is performed via the first gear train and a second mode where the power transmission is performed via the second gear train.
Claims6
A working vehicle comprising:
- a PTO shaft to extract power of a prime mover;
- a first PTO transmission shaft to receive power from the prime mover;
- a second PTO transmission shaft to transmit power to the PTO shaft;
- a first gear train and a second gear train to transmit power from the first PTO transmission shaft to the second PTO transmission shaft;
- a synchromesh switching mechanism to switch power transmission from the first PTO transmission shaft to the second PTO transmission shaft between a first mode where the power transmission is performed via the first gear train and a second mode where the power transmission is performed via the second gear train;
- a shift fork to perform a switching operation of the synchromesh switching mechanism to switch the power transmission between the first mode and the second mode;
- an operation mechanism to operate the shift fork to cause the shift fork to perform the switching operation of the synchromesh switching mechanism;
- a switch operable to output an operational signal to operate the operation mechanism;
- and
- a controller configured or programmed to, when acquiring the operational signal from the switch, output a control signal to actuate the operation mechanism.
A working vehicle comprising:
- a PTO shaft to extract power of a prime mover;
- a first PTO transmission shaft to receive power from the prime mover;
- a second PTO transmission shaft to transmit power to the PTO shaft;
- a first gear train and a second gear train to transmit power from the first PTO transmission shaft to the second PTO transmission shaft;
- and
- a synchromesh switching mechanism to switch power transmission from the first PTO transmission shaft to the second PTO transmission shaft between a first mode where the power transmission is performed via the first gear train and a second mode where the power transmission is performed via the second gear train,;
- wherein
- the first gear train is configured to transmit the power to the PTO shaft when a rotation speed of the prime mover is a first rotation speed;
- the second gear train is configured to transmit the power to the PTO shaft when the rotation speed of the prime mover is a second rotation speed different from the first rotation speed;
- and
- a gear ratio of the first gear train and a gear ratio of the second gear train are such that a rotation speed of the PTO shaft when the rotation speed of the prime mover is the first rotation speed is equal or substantially equal to a rotation speed of the PTO shaft when the rotation speed of the prime mover is the second rotation speed.
