When the HST pedal is pressed forward, the oil fed to the HST variable pump flows separately to the front and rear
wheel motors after the oil is changed via the 2WD/4WD valve. (red and light blue arrows in the diagram above)
Unlike the flow of oil during 2WD, the oil is supplied completely separately to the front and rear driving motors, and
therefore the sub-transmission shifts to "low".
Normally, this "low" speed is used for mowing work. However, it is also possible to use the "high" speed, depending on
conditions.
The returning oil forms a circuit as it returns from the front and rear wheels to the variable pump. (green arrow)
