DESCRIPTION
6 DESCRIPTION
The machine DUOLENT DX 380 NS, DX 460 NS, DX 550 NS is structurally solved as carried.
Machine DX 380 NS is equipped with TPS 2 and TPS 3 suspension. Machines DX 460 NS and DX 550 NS
are equipped with TPS 3 and „KIROVEC“ suspension. DUOLENT consists of a central framework and two fold-
ing side frameworks with two rows of shares with an automatic spring securing. There is a row of discs on
the rear crossbar of the framework. There are also swinging rear frames equipped with the rear roller at-
tached to the main frame . Side frameworks are unfolded with the use of rectilinear hydraulic motors con-
nected to the external hydraulic circuit.
6.1 Working parts of the machine
1. TPS towing suspension
2. Hydraulic motor
3. Machine framework
4. Setting the depth of the rollers
5. Rear roller framework
6. Spring protection
7. Sections of shares in 2 rows; screwed chisels with cutting wings
8. Sections of angle discs
9. Rear roller

DESCRIPTION
6.1.1 Description and setting of the ring roller
The roller with wheels consisting of ring segments is attached to the frame. There is a row of leveller
blades in front of the roller. The height as well as angle of the blades can be adjusted. The correct setting of
the blades is essential for the correct function of the roller. The setting of the blades must be first tested
and adjusted under factual conditions.
1. Roller frame 4. Front leveller blades
2. Roller cleaner 5. Bolts for adjusting leveller blades
3. Roller
Possibilities for setting front leveller blades
1. Front leveller blades located in front of the roller wheels throw clods directly under the wheels that
crush them.
2. Front leveller blades located between the roller wheels throw soil inside the wheels. Clods of soil are
thus partially crushed by the wheels and partially crushed inside the wheels. With this setting, the surface is
covered with soft soil after work.

* Recommended towing means, the real towing force may significantly vary according to the processing
depth, soil conditions, land slope, working body wear and adjustment.
• Connect the machine using the TPS suspension bar to the lower arms of the rear TPS of the
tractor, secure the TPS arms using pins against disconnecting.
• Connect the third point of the tractor only to the circular hole both for work and transport.
(concerns machine DX 380 NS).
• The machine aggregated with the tractor changes the distribution of the weight to the
individual axles of the tractor. The weight of the front axle is reduced and therefore the
controllability gets worse. It also affects braking properties.
When connecting, no persons may stay in the space between the tractor and the machine.
