HYDRAULIC UNIT 46
A
Do not hold the lever in the "pull" or "push" position
once the remote cylinder has reached the end of the
stroke, as this will cause oil to flow through the relief
valve. Forcing oil through the relief valve for extended
periods will overheat the oil.
A
When using the tractor hydraulic system to power front
loader, do not operate boom and bucket cylinders
simultaneously.
A
Connect the pressure of load side of implement
cylinders to ports [B] or [D] which have built in load
check valve to prevent leak down.
A
To use the single-acting cylinder with the float valve,
connect this cylinder to the [B] or [D] port.
To extend a single-acting cylinder, pull the remote
control valve lever rearward. To retract a cylinder,
push it fully forward to the "FLOAT" position. Do not
hold it in the down position, the transmission fluid may
be overheat.

Remote Control Valve Coupler
Connecting and Disconnecting
To avoid personal injury or death:
A
Stop the engine and relieve pressure before
connecting or disconnecting lines.
A
Do not use your hand to check for leaks.
C
Connecting
1. Clean both couplers.
2. Remove dust plugs.
3. Insert the implement coupler to the tractor hydraulic
coupler.
4. Pull the implement coupler slightly to make sure
couplers are firmly connected.
C
Disconnecting
1. Lower the implement first to the ground to release
hydraulic pressure in the hoses.
2. Clean the couplers.
3. Relieve pressure by moving hydraulic control levers
with engine shut off. Pull the hose straight from the
hydraulic coupler to release it.
4. Clean oil and dust from the coupler, then replace the
dust plugs.
A
Your local KUBOTA Dealer can supply parts to adapt
couplers to hydraulic hoses.
B
Flow Control Valve (option)
The optional flow control valve may be added for the
following purposes.
1. To operate within limits, the remote control valves (2)
or (3) above the flow control valve (4) and the 3-point
hitch at the same time without one affecting the other.
2. To operate within limits, the remote control valves (2)
or (3) above the flow control valve (4) and the other
remote control valve (1) at the same time without one
affecting the other. Activating the remote control valve
(1) will interrupt the operation of the 3-point hitch.
3. To maintain within limits, the constant speed of an
attachment (hydraulic motor RPM, for example) when
connected to the remote control valves (2) or (3) above
the flow control valve (4).
A
At slower engine speeds the total hydraulic flow rate
may be inadequate for simultaneous operation of the
remote control valves (2) or (3) and the 3-point hitch or
the remote control valve (1), or operation of an
attachment connected to the remote control valves
(1)(2)(3). Under these conditions, the engine speed
must be increased to provide additional hydraulic flow.
A
The remote control valves (2) and (3) above the flow
control valve (4) can not be operated at the same time.
