REMOTE HYDRAULIC CONTROL SYSTEM
A Before letting a large amount of oil into the hydraulic
cylinder, hydraulic motor or other implements, consult
your local KUBOTA Dealer to confirm the possible oil
quantity and additional oil quantity taken from the
tractor and other requirements.
Improper handling may cause serious trouble: seizure
of the transmission, for example.
BRemote Valve Controls
The external hydraulic power can be taken out of up to 4

an example.
Carefully check the relation between each valve and
control lever before connecting the hydraulic hoses.
