HYDRAULIC UNIT
3-POINT HITCH CONTROL SYSTEM
BHydraulic Control
Operating the hydraulic control lever actuates the
hydraulic lift arm, which controls the elevation of 3-point
hitch mounted implement.
To lower implement, move the hydraulic control lever
forward; to raise it, move the hydraulic control lever
rearward.
The positions (B) and (C) of the lever in contact with the
inner stopper enables you to control the valve with ease in
increments of approximately 6.4 mm (0.25 in.) at the lower
link end.
A If the 3-point hitch can not be raised by setting the
hydraulic control lever to the "UP" position after long
term storage or when changing the transmission oil,
follow these air bleeding procedures.
(1) Stop the engine.
(2) Set the hydraulic control lever to the down
position and start the engine.
(3) Operate the engine at low idle speed for at least
30 seconds to bleed air from the system.
A Do not operate until the engine is warmed up. If
operation is attempted when the engine is still cold, the
hydraulic system may be damaged.
A If noises are heard when implement is lifting after the
hydraulic control lever has been activated, the
hydraulic mechanism is not adjusted properly.
Unless corrected the unit will be damaged.
Contact your KUBOTA Dealer for adjustment.
