HYDRAULIC UNIT

HYDRAULIC UNIT
The standard tractor has 5 hydraulic control systems as
shown below. Therefore, use the most appropriate
system for the implement you are using.
C 3-Point Hitch Control System

1. Position Control

2. Draft Control

3. Mixed Control

4. Float Control
C Remote Hydraulic Control System
5. Combined Flow Control
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.

3-POINT HITCH CONTROL SYSTEM

BPosition Control
This will control the working depth of 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"
BDraft 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.

BMixed 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, the implement can be lowered, set the position
control lever at the lowest working depth desired for the
implement. Lower the draft control lever to the point where
the implement is at the desired depth.
This stops the implement from going too deep and
causing loss of traction and ground speed.

(B) "SENSITIVE"
(C) "INSENSITIVE"
(D) "FLOAT"
