3-POINT HITCH CONTROL
SYSTEM
WARNING
To avoid serious injury or death:
• Before using the 3-point hitch controls, make
sure that no person or object is in the area of
the implement or 3-point hitch.
• Do not stand on or near the implement or
between the implement and tractor when
operating the 3-point hitch controls.
1. Hydraulic control
IMPORTANT :
• 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.
• If noises are heard when implement is lifting
after the hydraulic control lever has been
activated, the hydraulic mechanism is not
adjusted properly.
If you do not correct the hydraulic control unit,
it will be damaged.
Contact your KUBOTA Dealer for adjustment.
Operating the hydraulic control lever actuates the
hydraulic lift arm, which controls the elevation of the 3-
point-hitch-mounted implement.
To lower the implement, move the hydraulic control
lever forward (the
position). To raise the implement,
move the hydraulic control lever rearward (the
position).
In the slow-down position and the slow-up position of
the hydraulic control lever in contact with the inner
stopper, you can control the valve with ease in the
following increments at the lower link end.
Increments at the lower link
end
approximately 6.4 mm (0.25 in.)
(1) Hydraulic control lever
(A) Down
(B) Slow down (C) Neutral
(D) Slow up

IMPORTANT :
• If the 3-point-hitch can not be raised by setting
the hydraulic control lever to the up (raised)
position after long term storage or when
changing the transmission oil, follow the
following air bleeding procedures.
1. Stop the engine.
2. Set the hydraulic control lever to the down
(lowered) position and start the engine.
3. Operate the engine at low idle speed for the
following seconds to bleed air from the
system.
Operating the engine at low idle speed at least 30 seconds
2. Lowering speed of 3-point hitch
The lowering speed of the 3-point hitch can be
controlled or locked in similar fashion to a water faucet.
WARNING
To avoid serious injury or death:
• Fast lowering speed may cause damage or
injury. Lowering speed of implement should be
adjusted to 2 or more seconds.
Turn toward the fast position to increase, the slow
position to reduce, and the lock position firmly to the
stop for lock.
