The rake should be attached to a tractor with use of tractor's lower pull-cables as provided in
Fig. 8. For this purpose drive the tractor at the rake's catch, and then place hangers W of
tractor's lower pull-cables on pins S on the rake's linkage.
Once the rake is mounted turn support leg back (Fig. 8).
Connect hydraulic hoses.
Connect machine's controller to tractor's lighter outlet (12V) by means of a plug and a three-pin
plug to socket on the rake's linkage. Fix the controller in tractor's cabin by means of magnetic
holder in a visible place.
Connect the machine's lighting cables to the tractor and check the lights for operation.
Connect telescopic articulated shaft. If need be shorten the shaft as per item 5.4.

5.1.1. Control panel
Controller (Fig. 9) enables switching the rake's working units to working position (lowering)
and transport position (lifting). During the machine operation, if diode (1) is lit the sequential lifting
and lowering of working units function is enabled. Button (C) is for switching between the panel
functions. Once button (C) is pressed the diode (1) goes off, a diode (2) will light up to indicate
deactivation of sequential lifting and lowering function and thus activation of folding the machine
for transport and unfolding it for operation function. Once this option is enabled the working units
will fold and unfold steadily. Note: once diode (2) lights up the function remains active for 60
seconds. This time is sufficient to fold the machine to transport position or unfold it to working
position. As the 60 s time elapses the panel will go to sequential operation mode.

5.3. Preparing rake for transport on public roads
To meet safety precautions concerning transport on the public roads the rake should be
equipped with warning triangle, attached at the rake's rear (the plates are standard-delivered with
the machine.) To improve safety during the transport the machine should be fitted with a warning
triangle – to be purchased at the manufacturer.
When transporting on public roads respect provisions valid in the country of use.
NOTE:
If the rake's owner does not own the above warning lights and plates, these can be ordered at
the manufacturer.
5.4. Mounting telescopic articulated shaft
Mount the shaft with wide-angle joint from the rake side.
The guard should be protected against rotating by securing the shaft set chains to immovable
parts of the tractor and the rake.
NOTE:
If necessary shorten the shaft as provided in the corresponding operator's manual (Fig. 12).
Fig. 12. Telescopic articulated shaft shortening instructions
CAUTION!
The articulated telescopic shaft should remain connected only during rake
operation. During transport or any servicing operations the shaft should be
disconnected from the PTO of the tractor.
CAUTION!
Use machines with correspondingly designed driving PTO shafts. Before
work, safety guards should be inspected whether they (in the tractor, the rake
and the PTO shaft) are placed correctly and are not damaged. Damaged or
missing parts must be replaced. Make sure that the PTO shaft is mounted
properly. Approaching the rotating parts is strictly forbidden, as it may cause
serious injuries or even death. For any service and repair works on the shaft
and the rake, makes sure that the tractor’s engine and its drive is turned off.
Before operation, read the operator's manuals of both the machine and the
PTO shaft
.
NOTE
PTO shaft’s end with friction clutch should be mounted at the rake’s side.

5.5. Switching rake from transport to working position
make sure there is no person around the danger area where the machine is to be lowered,
lower rake's arms by means of hydraulic lifter as slow as possible in order to better absorb it
when touching the ground,
remove raking arms from transport holes, mount them in the rotor and secure with cotters,
lower safety guards.
5.6. Preparing rake for operation
NOTE:
For the machine storing period, cylinder rods are lubricated as SaMASZ with protective
grease in order to protect them against weather conditions able to shorten their service life.
Before operating the machine remove excess grease coming out from cylinder rods.
Due to large dimensions of rake TANGO 730, extreme most arms are originally dismounted
on each rotor for transport purposes (TIR). In order to dismount these quicker they are mounted in
factory with bolts. For operation purposes put expansion pins which are provided with the machine
instead of factory bolts as given below:
unscrew bolts from rake's arms on each gear (Fig. 13),
support rake's arm to avoid damaging the gear's connecting rod (Fig. 14),

5.7. Operation
Rotary rake is used for raking up swath or grass after tedders. The driving speed should be the
result of ground configuration, quantity of grass, and raking cleanness. Depending on setting the
working assemblies' operating widths, the rake will be able to form either one, or two rows. When
forming two rows, both swath screens should be lowered.

ground unevenness (e.g. stones) is levelled by movable, tandem wheels on the driving trolley.
5.8. Mechanism for sequential lifting and lowering of working units
Due to the rake's design, where working units are arranged in different distances in relation to
the tractor, a mechanism for sequential lifting and lowering of working units is applied, and it is
used when driving the machine to and from a meadow. When driving to a meadow and after
switching hydraulic section to floating position, the front working unit lowers and starts raking, and
in a while the rear enters the grass, lowers and starts raking as well. When leaving a meadow the
rotor at the tractor's side lifts up to headland position as first.
5.8.1. Sequential lifting
When switching to transport position, the rear rotor's hydraulic assembly remains locked until
the front rotor reaches the transport position. Only afterwards hydraulic lowering of the rear rotor is
released. When switching from transport position to working position the rotors lower in the reverse
order.
Switching time of the control valve (Z) is adjusted with screw (S) on the cam (K) (Fig. 26).
Turn the screw counter clockwise to set shorter time of delay in lifting of the rear unit against the
first unit. Turn the screw clockwise to set longer time of delay in lifting of the rear unit.

5.10. Switching rake from forming one row to forming two single rows
In order to switch the machine for raking two rows, perform the following:
fold out working assemblies with tractor's hydraulics, so that raking tines on front working
assembly do not overlap with tines on the rear assembly,
open valve on tarpaulin cover mechanism cylinder.
Switching the valve shall cause the cover to get lifted as headlands with working assemblies,
and be set for operation as the machine starts raking.
When forming two rows the rear cover is set the same as when forming a single one.
Once the work is completed, first lift the tarpaulin cover mechanism (Fig. 28) and secure the
valve on cylinder (Fig. 29). Working assemblies can be slid down only when the mechanism is
secured.
CAUTION:
When sliding down the working assemblies, pay particular attention to

5.10.1. Protection mechanism of front safety curtain
The mechanism is designed to provide protection of front safety curtain against damage in the
event the curtain was not locked in the upper position by shut-off valve, and the rotating working
units will be slid down.
Fig. 32. Protection mechanism of front safety curtain
This mechanism is operated by means of lever (1), which, as the working unit approaches the
rake's linkage, is pushed away by pin (4) located on pull-out arm. The lever has a line (2) attached,
and with its use, along with the lever, push-off arm (3) operates. It is intended to protect the curtain
against damage by pushing it to a safe distance away from an operating rotor. With adjusting nut (5)
it is possible to set a safe distance for safety curtain from raking arms of the working unit.
5.11. Lifting rake on headlands
When lifting arms with working assemblies (A) and (B) the pawl (3) will be locked
automatically in position for headlands (Fig. 34). To lift working units to transport position, on the
