HYDRAULIC UNIT
IMPORTANT :
• Do not operate until the engine is warmed up. If
any operation is attempted when the engine is
still cold, the hydraulic system may be
damaged.
• If noises are heard when the 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 adjustments.
A standard tractor has the following hydraulic control
systems. Choose the most appropriate system for the
implement you are using.
3-point hitch control system
• Position control
• Draft control
• Mixed control
• Float control
Remote hydraulic control system
3-POINT HITCH CONTROL
SYSTEM
WARNING
To avoid personal injury or death:
• Before using the 3-point hitch controls, ensure
that no person or object is in the area
surrounding 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. Position control
This will control the working depth of the 3-point hitch
mounted implement regardless of the amount of pull
required.
(1) Position control lever
(2) Draft control lever (A) “FLOAT”
(B) “DOWN”
(C) “UP”
2. Draft control
This will control the pull of the 3-point implement.
As the load on the 3-point hitch changes due to various
soil conditions, the draft control system automatically
responds to these changes by either raising or lowering
the implement slightly to maintain a constant pull.
Place the position control lever in the lowest position
and set the implement pull with the draft control lever.
(1) Draft control lever
(2) Position control lever
(A) “SENSITIVE” (B) “INSENSITIVE”
(C) “FLOAT”
3. Mixed control
In draft control, when draft decreases, the implement
automatically lowers to increase draft.
However, the implement sometimes lowers too much.
To limit the degree to which the implement can be
lowered, set the position control lever at the lowest
working depth desired for the implement. Lower the
