4.9.4.2 TOP LINK
Optionally, the user may replace the standard mechanical top link with a hydraulic top link for
hydraulic adjustment of the top link or the connection bar, which is used for connecting the third
linkage point, directly from the driver’s seat by means of a shift lever. See Fig. 84.
4.9.4.3 VERTICAL HYDRAULIC TENSIONER
The rear lift mechanism can also be optionally upgraded with a lift rod for the hydraulic version.
•
Standard lift rod
As standard, the hydraulic lift mechanism is
equipped with two lift rods, one on the left and
one on the right side.
•
Hydraulic lift rod
There is only one hydraulic lift rod installed on
the right side of the hydraulic lift mechanism,
see Fig. 93.
The hydraulic lift rod is used for adjusting the
height of lower link arms directly from the
driver's seat by means of a shift lever.

4.9.4.4 DOUBLE-ACTING HYDRAULIC LIFT CYLINDER
As standard, the rear hydraulic lift mechanism operates on the principle of a one-way system and
the operator may choose to optionally upgrade the rear mechanism to a two-way system to
control the lifting and lowering operations through a control lever on the control device. See Fig.
84.
Hydraulic lift mechanism operation
The rear hydraulic lift mechanism is controlled by two hydraulic cylinders, providing the ability
to select between one-way or two-way operation in connection with a three-way valve.
•
One-way operation of hydraulic cylinder, the pressure from hydraulic oil acts on the
piston in the cylinder from one side, which allows the cylinder to be moved in one
direction (lifted), while the return movement (lowering) is achieved by an external force,
generated by the implement weight or a spring.
