1DESCRIPTION
The SOFTER PRO machine is constructed as semi-carried. The basic version consists of a drawbar
equipped with a loop for the fixed suspension pin or carrier bar for TBZ, a central frame with the transportation axle
two side frames. There are working discs in two rows on the central and side frames. There are rollers in the rear
that compact the loosened soil.

•The panel is located on the left side of the drawbar (Chyba! Nenalezen zdroj odkazů.)
Attention! The machine may move suddenly when some of the valves are changed over.
Safety axle lock and folding
Locking for transport
The red (folding) and yellow (axle) circuits are
closed. The circuits cannot be moved. Lever
position –on the left.
Used for transport.
Field work
The red (folding) and yellow (axle) circuits are
open. Lever position –on the right.

Turning at headland
•Used to lock the axle for turn at headland
•The machine moves only on the roller when working in the field
Transport
The yellow circuit is used to move the drawbar,
axle and central roller. It is used for conversion
between the working and transport position of
the transport axle and the middle roller.
Used for transport and folding. The circuit can
also be used for work with turning on the axle.
Field work
Axle and middle roller are locked. The machine
only lifts on the drawbar. Lever position –on the
right.
Used at work.
Disc circuit closure
•Used to restrict unintentional movement of discs when the machine is folded.
•The machine only meets the required width of 3 metres for road traffic with disc depth set at minimum.
•The unintentional movement of discs may also be caused when the yellow axle circuit is used (linked
function). The valve closure prevents that.
Locked discs
The green circuit valve is closed. Discs cannot be
moved.
Discs must be maximally drawn in for folding.
The valve must be closed.
Used for transport and folding.
Unlocked discs
The green circuit valve is open. The working
depth can be adjusted.
Used for work.

Shut-off valve on the drawbar hydraulic cylinder
•Used for closing the supply of pressure oil to
the drawbar piston-rod.
•Prevents the machine from dropping when
the hose breaks during transport.
•It does not need to be closed when the
machine is resting on the drawbar washers
for transport.
Axle valve for lowering the machine
•The valve is located on the central roller beam
•It is used for achieving the lowered transport position with height below 4 metres or for turning on the axle
•The valve closes oil supply to the long axle piston rod on the central frame
•The piston rod must be extended at maximum prior to closing in order to achieve proper transport position
Attention! Pay extra attention when the valve is open. The machine may start moving unexpectedly.

1.4 BRAKE DISTRIBUTION OF THE MACHINE
•The standard version of the machine includes a single-circuit two-line braking system by KNORR BREMSE
•Braking is provided by pneumatic brake cylinders.
•The parking brake is mechanical, controlled by a jack on the axle.
•Always check that the parking and operating brakes are released prior to driving.
•If the machine is equipped with brakes, they must be connected to the tractor when driving.
•Always release the brakes of the machine when lifting the machine on the axle.

1.4.2 Hand brake control valve
The manual brake is controlled with a jack and a lever on the axle. When engaging and releasing the brake, always
turn the jack to the end stop. The parking brake is only functional when the step of the brake levers on both wheels
is correctly adjusted.
Attention! When air brakes are used, the parking brake jack must be released all the way. If the jack is not released
all the way, it might continue braking slightly when the air brakes are released.
1.4.3 Emergency pneumatic brake control
•The emergency brake is automatically activated when air brakes are disconnected
•The activation only happens when there is sufficient pressure in the air tank
•You can use the black button on the brake switchboard to release brakes for manipulation
•When the system is pressurized, it automatically switches to the driving (extended) position
