Design of the central lubrication system
An electrically driven piston pump delivers lubricant to the main progressive distributor. Its task
is to distribute grease to the sub-progressive distributors at the correct ratio. Then, the sub-
progressive distributors pump the grease to the individual lubrication points. The lubrication
duration and the break times are controlled via terminal,

The hydraulic system of the machine is designed for tractors with a
constant flow system
and
for tractors with a
Load Sensing system
.
The hydraulic system of the machine has been set at the factory for tractors with the
constant
flow system
. In doing so, the system screw (1) has been completely unscrewed from the
control block.
The hydraulic system is adjusted to the hydraulic system of the tractor
(constant flow system
or Load Sensing system)
via the system screw (1) on the control block of the machine,
.
The control block is at front on left under the side hood next to the electronics box.
