An articulate vehicle has first and second frames, which are coupled to each
other
at proximal ends thereof with respect to the vehicle through a coupling part so
as to be relatively rotatable around a vertical axis according to steering operation.
The first and second frames are distributed at front and rear portions of the vehicle.
The first frame supports a first transaxle apparatus having first axles, and the
second frame supports a second transaxle apparatus having a pair of second axles.
A gearbox is disposed near the coupling part and provided with a pair of mutually
drivingly connected horizontal shafts which are variable in relative angles thereof
around the vertical axis according to steering operation. One of the horizontal
shafts is drivingly connected to a power take-off shaft for extracting output power
of a speed-changing arrangement in the first transaxle apparatus. The other of
the horizontal shafts is drivingly connected to an input shaft of the second transaxle
apparatus. The vehicle is provided with a rotor having a rotary axis disposed on
the vertical axis so as to output power from a prime mover to a working device.
