Wheel motor
This converts the fluid energy from the pump
to mechanical energy (rotation motion) in
order to directly drive the machine.
This is located at each wheel.
Orbitrol
This is a fully hydraulic power steering unit,
switching of the internal valve depending on
the rotational input from the steering wheel
causes oil from the hydraulic pump to be fed
to the steering cylinder.
It is located in the front part in the center
cover.
2WD/4WD changeover valve (KVS-65K-2)
This channels the fluid energy from the two
piston pumps to the wheel motor of the
vehicle by manual changeover composed of
multiple valves.
If the valve position is 4WD, the fluid energy
is channeled from the front piston pump to
the front wheel and from the rear piston
pump to the rear wheel.
If it is 2WD, the fluid energy from the two
piston pumps converges and flows into the
rear wheel.
It is located in the rear left part of the main
body.
Solenoid valve (HF78806-12)
This raises and lowers the mower unit by
channeling the fluid energy from the gear
pump to the up or down side of the up/down
cylinder by changeover of the flow channel
by opening and closing the electromagnetic
valve.
It is located in the rear right part of the main
body.
Piston pump
This converts the mechanical energy of the
engine to fluid energy by using the
reciprocating motion of the piston.
It is located in the center of the main body.
Gear pump (w/piston pump)
This converts the mechanical energy
(rotation motion) of the engine to fluid energy
by using two gears.
It is installed in the front part of the piston
pump. 1.

Steering cylinder
According to the control valve that is
activated depending on the steering
operation, the flow of the fluid from the
hydraulic pump is changed to steer the
vehicle to the left or right.
This is located between the front tires.
Up/down cylinder
This converts the fluid energy from the pump
to mechanical energy (reciprocating motion)
in order to raise and lower the mower unit.
It is located inside the fuel tank.
Relief valve (DVR04)
This automatically opens the valve and emits
fluid if the pressure reaches the specified
level and closes the valve if the pressure
drops, in order to protect the equipment.
It is installed in the upper part of the
2WD/4WD changeover valve.
Cartridge filter
This removes dirt or dust in the outgoing
fluid.
This fulfills an essential role since elements
that could cause major problems may be
circulated if there was no filter.
It is located in the rear right part of the main
body.
Filler neck breather
While hydraulic mechanisms are functioning,
the oil level is regularly raised and lowered.
In addition, due to atmospheric pressure
fluctuations as well as temperature
fluctuations, air is flowing in and out of the
hydraulic tank.
Therefore, the vent at the top of the hydraulic
tank has an air breather so fresh air can flow
in.
This is located in the oil filling port of the
hydraulic tank. 7.
