A vehicle transmission housing has first and second axle housings pivotably connected to opposite ends of the transmission housing and a stand-on platform may be connected to the assembly. A first gear train in the first axle housing drives a first axle having a first axis of rotation. A second gear train is disposed in the second axle housing drives a second axle having a second axis of rotation collinear with the first axis of rotation. The axle housings are both capable of pivoting about the transmission housing about a third axis that is parallel to the first and second axes. The first and second axle housings may also be separately rigidly or flexibly connected to one another. This assembly permits adjustment of the ground heights of the platform with respect to a vehicle frame.

A power transmission device includes a first shaft provided to be rotatable around a first rotational axis of the hydraulic pump driven by the engine. A second shaft is rotatable about the first rotational axis to rotate the power take shaft. A clutch is rotatable about a second rotational axis that is substantially parallel to the first rotational axis and is vertically below the first rotational axis. The clutch has a first rotating portion and a second rotating portion arranged to face each other in the second rotational axis. A first rotating portion is connectable to and separable from the second rotating portion. The first rotation transmission mechanism is configured to transmit rotation of the first shaft to the first rotating portion. A second rotation transmission mechanism is configured to transmit rotation of the second rotating portion to the second shaft.

This work vehicle (tractor), which is provided with an engine and an accelerator pedal capable of changing the operational state of the engine, and is configured to be free to travel by means of an operation of the accelerator pedal by an operator, is equipped with a display near an operator's seat, said display being configured to be capable of displaying a screen (travel customization screen) for selecting whether or not to allow travel in conjunction with the accelerator.

A hydraulic continuous variable transmission is provided to connect a wind turbine and a generator. The hydraulic continuous variable transmission has a primary paddle wheel and a number of secondary paddle wheels for macro speed control. Also provided are pneumatic paddle wheels for micro speed control. A controller is included that measures AC electrical characterized output to load or line for speed control.

A work machine control system includes an operational input portion that accepts an input operation to change a position of acceptance, maintains the position of acceptance when there is no input operation accepted, and provides an operation command in accordance with change in position of acceptance, an operational force providing portion that provides a plurality of operational forces in correspondence with an amount of change of the position of acceptance, a transmission portion that changes a speed of rotation provided from a drive source to transmit resultant rotation to a drive wheel, and a controller that controls the transmission portion based on a travel speed of the drive wheel in accordance with the operation command.

A working vehicle comprises: a vehicle body; a linkage device configured to link a working device to the vehicle body; a prime mover provided on the vehicle body; a traveling device configured to cause the vehicle body to travel; a transmission device configured to transmit power from the prime mover to the traveling device and perform a speed change process to change a speed of the vehicle body; an increase-in-speed detection device configured to detect an increase in speed of the vehicle body; and a speed change restraint unit configured such that, during the speed change process performed by the transmission device, when the increase in speed detected by the increase-in-speed detection device has become equal to or greater than a threshold, the speed change restraint unit stops the speed change process performed by the transmission device.

A shift power transmission apparatus of a tractor that has a small up-down width or a small transverse width and a short front-rear length. A shift output unit is located further toward a vehicle rear side than a combined planetary power transmission unit. A planetary unit output axis and a shift unit input axis are coaxial with each other. A power transmission unit, that transmits motive power from an engine to a continuously variable transmission unit and the combined planetary power transmission unit, includes a rotary power transmission shaft, a pump transmission unit and a planetary transmission unit, the rotary power transmission shaft being interlockingly joined to an output shaft of the engine and extending in a direction along a vehicle front-rear direction, the pump transmission unit being configured to input motive power of the rotary power transmission shaft to the continuously variable transmission unit, and the planetary transmission unit being configured to input motive power of the rotary power transmission shaft to the combined planetary power transmission unit.

A work vehicle such as a tractor including an engine, a battery, a hydraulic continuously variable transmission, and an electric cylinder, and a power transmission mechanism. The hydraulic continuously variable transmission changes an output of the engine, and changes an angle of a movable swash plate to change a gear ratio thereof. The electric cylinder is driven by electric power supplied from the battery at least while the engine is stopped. With the power generated in the electric cylinder and transmitted, the power transmission mechanism changes the angle of the movable swash plate of the hydraulic continuously variable transmission.
