4. Intended use of the machine
The rotary mower is designed for agricultural applications, mowing of the low growing green forage like
grasses, alfalfa, etc., on fields and meadows with flat surfaces.
It can be used in fields and meadows, which contain no stones, are flat or slightly undulating, with the slope
of up to 10 °.
The mower is a machine suspended on the three-point hitch system of the category I and II tractor. The
working elements are two rotating discs, fitted with blades. This unit is driven from power transmission shaft,
through articulated telescopic shaft and belt transmission to bevel gears. The bevel gears are embedded on
the drive shafts, which drive the discs.
Complying with the requirements related to the use of the machine, its operation and repairs, strictly
according to the manufacturer's guidelines, is the precondition of the use of the machine as intended. The
machine should be used, operated and repaired only by persons familiar with its specific characteristics, who

5.2. Technical characteristics
The overall construction of the mower is shown in the following figure.

15
Figure 2 Overall machine construction: 1 - suspension frame; 2 –main chassis; 3 –hydraulic cylinder (depending on the model);
4 –cutting unit; 5 –cover assembly; 6 –working section of cutting unit;
7 –support foot.
Suspension system frame is used to connect the mower to a tractor. Through centre frame, the suspension
system frame is connected to the complete working unit with covers.
The working unit consists of two working drums, with cutting blades rotationally embedded in the lower part
of the drums. Diagram of the drive system is shown in Figure 3.
Figure 3 Eco CUT 210 drive system diagram: 1 –articulated telescopic shaft with one-way clutch; 2 –drive head shaft; 4 –V-belt
transmission; 5 –main frame shaft; 6 –bevel gear; n1 –rotational speed of tractors PTO; n2 –rotational speed of drums (values
given in Table 2); z1 –large bevel gear; z2 –small bevel gear.
The drums are driven by the tractors PTO shaft. Together with the blades, they rotate in opposite directions,
cutting plants and forming green forage in a swath. The one-way clutch allows the drums to rotate freely
after the engine is shut off, and protects the driving elements from damage.
Technical-operational data for mowers are provided in Table 2 (below).

6. Machine usage
The manufacturer declares that the machine is fully functional. It has been inspected in accordance with the
quality control procedures and approved for use. However, this does not relieve the user from the obligation
to inspect the machine after its delivery.
Before every time the machine is used, its mechanical condition needs to be checked, and
especially the condition of cutting unit, drive transmission system, hydraulic system and guarding
shields.

17
6.1. Mower assembly
The distributor delivers a complete mower with a cover of the cutting unit. Installation of the cutting unit
cover must be done by the user or dealer.
Working without the cutting unit cover, or with the cover damaged or raised, poses a danger
for an operator and for environment –Strictly prohibited.
Instructions for the cover unit installation are provided in the paragraph “13.2.8 Cover unit”.
6.2. Connecting the mower to a tractor
Make sure that the connecting parts of both, the vehicle and the machine, are suitably adjusted
to each other.
In case of any doubt, always ask the vehicle or the machine distributor.
The mower should be connected with the tractor by means of a three-point hitch suspension
system. During connection, the mower should be in transportation position.

18
Figure 3 Aggregating –connecting the mower
In order to connect the mower to the tractor:
1. On the pins (Fig. 8, item1) of the suspension frame, fit the tractor’s lower connectors (first left, then
right), and secure them with linchpins.
2. Insert the top connector’s tip between the yoke plates, using the holes (Fig. 8, item 2), thenconnect
with a pin and secure with a linchpin.
3. Raise the mower to take the weight off the support foot.
4. Raise the support foot and secure it with a cotter pin.
5. Connect the chain to the transportation hitch or its bracket.
Adjust length of the articulated telescopic shaft to the tractor, according to the shaft’s instructions.
6.3. Transport position
For the mowers transportation, it should be set in the transportation position.
Articulated telescopic shaft must be detached from both, the tractor and the mower.

19
For mower models with hydraulic cylinder 2.10m:
1) transport position 2) working
position
1. Park the tractor and mower on a flat, even surface,
2. Remove the securing element from the upper pivot of the suspension frame,
3. Raise the mower with a hydraulic cylinder of the tractor, so that the sliding discs do not
rest on the ground,
4. Raise the support foot to the upper position, and secure with a cotter pin,
5. Manually place the mower in transportation position, so the interlock pin is inserted into
the hole in clevis (rope must be loose) (Fig. 11A),
6. Bring the cylinder to transportation position, until the cylinder lock gets triggered (Fig.
13A). Transport position is shown in the Figure 13.

Figure 4 Proper transport position for 2.10m mowers
Closing the cylinder for Eco CUT 210 mower for transport is shown in the figure below.
Lock pin - Pos. 1 should lock into the cylinder handle (lower the mower until the pin is completely locked).
The ball valve lever should be moved to the closed position - Pos. A.
However, for operation, the valve lever should be moved to the open position - Pos. B, and open the lock
with the cable until the lock is released.
