HYDRAULIC UNIT
3-POINT HITCH CONTROL SYSTEM
B
Hydraulic Control
Operating the hydraulic control lever actuates the
hydraulic lift arm, which controls the height of 3-point hitch
mounted implement.
To lower implement, push the lever forward; to raise it, pull
the lever back. After setting the implement to the desired
height, move the lever back to "NEUTRAL" position.
The lever position (C) enables you to control the valve
with ease in increments of approximately 1/4 inches 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,
turn steering wheel to the right and left several times
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.
B Implement Lowering Limit
The implement lowering limit can be changed by shifting
the locker (A).
Lower Limit
The lower limit can be changed by adjusting the position
of locker (A). Shifting the locker (A) backward raises the
lower limit and shifting it forward lowers the lower limit.
