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.
BRemote Control Valve Lever
Move the lever up or down and hold. This will raise or
lower the implement. Lever will return to neutral when
released.
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.
