WARNING : To avoid inadvertent movement of
the implement, disengage the P.T.O. after each use.
5.8 HYDRAULIC SYSTEM
Your tractor is equipped with a hydraulic system
providing accurate and sensitive control over a wide
range of operating conditions.

Two distinct systems are incorporated
1. Draft Control lever 2. Position Control lever
The type of control selected will depend on the type
of implement in use and the operating conditions.
1. Draft Control is most suitable for soil engaging
implements operating in the ground. Changes in the
working depth or soil resistance cause the draft
loading on the implement to increase or decrease.
This change in draft loading is sensed through the
top link of the three-point linkage and the hydraulic
system responds by raising or lowering the
implement to restore the draft loading. In this way a
uniform draft load is maintained on the implement.
2. Position Control provides accurate and sensitive
control of implements such as sprayers, rakes,
mowers, etc., that operate above the ground.
Position Control would not normally be used with
ground engaging equipment unless it is essential to
maintain a constant depth regardless of the draft
load.
The tractor has a dual lever system, i.e., separate
levers for Draft and Position Control functions. See
Figure 6.
The Draft and Position Control levers are used to
raise or lower the three-point linkage (and
implement) to the required height or working depth.
WARNING: Do not transport or attach
equipment when the hydraulic system is in Draft
Control Use position Control for these operations
Always lower hydraulic equipment to the ground
before stopping the tractor.
OPERATION
There are three positions of PTO selection lever,
Position (1) is for normal operation of 540 rpm, position.
(2) is neutral and position (3) will select 540E RPM.
Please select 540 rev/min or 540E rev/min mode by
using dual PTO lever. Set the engine rpm to 1728
rev/min for 540 rev./min and engine rpm to 1251 rev/min
for 540E rev/min.
Bring PTO selection lever (2) to engaged position by
pulling it up.
IMPORTANT : Always disengage the independent PTO
clutch lever before engaging or dis-engaging the P.T.O.
to prevent damage to P.T.O. components.
