WARNING:
Keep the PTO shaft in engage position (PTO clutch lever fully lowered) irrespectively of
the PTO selector lever.
Before select PTO speed pull the PTO clutch lever fully.
To select PTO speed move the PTO selector lever (7
– Fig. 3.2). There are three positions as shown
on sticker beside the lever:
1 - independent PTO engaged
-
Independent
2 - neutral
-
N
3 - ground PTO engaged
-
Ground
Shifting the lever to engage position pull the PTO clutch lever fully(6
– Fig. 3.2).
When shifting the lever to the ground PTO engaged, there is obtained PTO speed depending on
tractor speed. Tables with ground PTO speed are in chapter 2.3.
Independent PTO drive means that the PTO shaft rotates proportionally to engine rotation. There is
possibility to select two speeds: 540 rpm and 1000 rpm (by engine rated rotation speed).
If required to drive implements of higher PTO speed (1000 rpm), select forward position of the lever
(10 - Fig. 4.6.2) placed above PTO shaft end. When 1000 rpm PTO is engaged the yellow indication
light illuminates on the pulpit (27- Fig.3.1).
!
WARNING:
When
1000 rpm PTO is engaged
don’t use implements adapted to low PTP rotation to avoid
damage of the implement and danger
4.5. Tractor hydraulic system.
Your tractor is equipped with a hydraulic system providing accurate and sensitive control over a wide
range of operating conditions.
This system provides the following functions:
Draft Control
– is most suitable for mounted soil engaging implements. 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.
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 soil
engaging implements unless it is essential to maintain a constant position of the equipment
regardless of the draft load.
Sensitivity Control
– provides smoother response to draft signals while using soil engaging
implements.
Flow Control
– is provided to control the rate of drop of the lower links and for locking of the lower
links in raised (transport) position.
External hydraulics control
– is provided to control the external equipment that requires hydraulic
power for its operation, such as trailer tipping, loader operation, hydraulic motor drive, etc.
4.5.1. Hydraulic lift system.
Control levers (Fig. 3.2)
Draft Control lever 12 (next to the seat)
– yellow knob, is used to adjust the draft i.e. working
depth,
Position Control lever 11 (next to the mudguard)
– red knob, is used to adjust the
position/height of the implement and lets you lift or lower the implement,
Sensitivity Control knob 14,
