5. USE OF RAKE
5.1. Mounting rake on tractor
Rake TANGO 730 cooperates with tractors with power from 60 HP.
 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 Wof
tractor's lower pull-cables on pins Son 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.
Fig. 8. Rake mounted on tractor
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.

In order to prepare the rake for transport and- drive on a road-:
 due to safety reasons, before setting the rake to transport position turn off the PTO shaft; raking
arms cannot be in motion,
 lift safety guards to transport position,
 take out the extreme most raking arms from a rotor, place them in transport holes (depending on
max. height of obstacles under way) (Fig. 10),
 lower and secure a support leg,
 lift working assemblies and secure them with a pawl,
Fig. 10. Transport dimensions
NOTE:
Once the machine is set to transport position, check whether mechanical locking pawls are
properly locked on pins.

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),
Fig. 13. Temporary mounting of arms Fig. 14. Supporting rake arm
 hammer expansion pins into holes where bolts were previously placed. put pin Ø10 and Ø6 into
each one hole (Fig. 14).
Fig. 15. Hammering dowel pins Fig. 16. Properly hammered pins
Before commissioning of the rake, in driving wheels (Fig. 17), replace provisional bolts (S)
on joints of steering heads with rear wheel axis for expansion pins Ø16 and Ø10 (K) delivered with
the machine. Install the pins as shown in Fig. 16.

Fig. 17. Preparing drive system of the rake
The following should be performed in workplace and as rake is in working position:
 connect PTO shaft extension onto tractor's spline shaft (if only one extension was taken out) or
connect the complete PTO shaft,
 set the tractor and rake aggregate on an even, level ground,
 lift or lower adjustment lever (Fig. 18) to set the required raking height. Recommended distance
of raking tines and the ground is 0.4'' (1 cm) (Fig. 21).
Fig. 18. Raking height adjustment lever
WARNING!
It is forbidden to lower raking arms below 0.4'' (1 cm) from the ground as
this may cause damages to the machine such as bending the raking arms,
breaking the linkage or the gear, faster wearing of raking tines, damaging the
turf and causing contamination to the collected forage, etc. Too high a raking
set may cause the swath not be collected completely.
