ASSEMBLY
Assembly is highly dangerous and must be carried out in strict accordance with the following
instructions. We recommend that qualified personnel perform assembly. We also recommend that
assembly be carried out in a flat, solid surface, open area with no people (particularly children)
nearby who could be severely injured if they were to touch or move any parts of the machine.
Assemblers must provide suitable lifting mechanisms and supports for stabilizing the partially
assembled units, so as to prevent them from falling and causing damage or injury. The steps for
assembly are illustrated in following. Depending on the experience of the assemblers and the tools
available, it is not necessary that the instructions be followed in the exact order given here, but the
safety precautions described above must always be followed carefully and scrupulously.
Assembly seguence:
The following pictures , used to describe the rotary rake’s assembly, refer to model 420/11.
On the 320/8 model there are small differences in the shape of components.
The person in charge of assembling the rotary rake should verify in the parts book the small
differences existing compared to the bigger version. The difference in the building’s shape
does not change the function nor the performances.
ATTENTION
For the model 320/8 standard, fit the wheel 26 directly to the outer pins of axle 17. For the
model 320/8 with tandem wheels , fit the lock pins as per spare-parts’ drawing 920.138. For
machines with tandem wheels keep in mind to grease the pin regularly 210.967/a.
Attach the arms (2) to the housing (1), placing them over the pins (3). Fasten the arms by
inserting spring pins (4) into holes (A), and then insert the inside spring pins (5). Attach
grease nipples (16) to the axle (17). Next check to see that the wear bushings are in place on
the wheel tandems (23), and mount the tandems on the axles, inserting spacers (21), in
order to limit play (the longer part of the wheel tandem should face the tractor), and fasten
with the washer (24) and nut (25). Mount wheels (26) on the tandem pins, first placing the
large guard (27) and then the small guard (36), the washer (34) and tighten with the nut (35).

13
Attach the pin (20) to the drawbar (40) and fasten on the lower part with the washer (13) the wear
preventing bushing (10) and the bushing (8) with the spring pin (9). Insert the 3rd point arch (1) bended
in order to overlap the slot and the bushing (10) then place the arch in order to insert the pin (18) and
the spring pins (19). Mount the linkage brackets (2) and (3) by inserting pins (4) and spring pins (5).
Mount the parking stand (41) to the mounted on the 3point hitch (1), and fasten with pin (44) and clip
(42). The machine can now be placed on the ground. Rotating 3rd point hitch (1) as regards to the
drawbar, then insert the spring (38) into the outer shock absorber (37) and into the inner one (39).
Attach the shock absorber to the proper hitches by inserting pins (35) and (40). Repeat the same
operation on the opposite side of the machine.

14
Mount the support (31), plate (27) and ratchet (23).
Insert the crank (25) on the supports, and then attach the flexible joint (11) connecting
it also to the adjusting screw by the spring pins (12). Take off the guard (A) from the
screw.

15
Mount the right-hand protection frame 2-3by inserting into the special hole (A) on the
drawbar and use screw 8 and pin 14 to fasten it.
Repeat the procedure on the left-hand protection of the machine.Assemble support 6 and
9 using screw 17. Use pin 11 to fasten the protection. Mount pin 20 and plate nut 21.
In order to mount swathing deflector 29 insert the slanting metal tabs 31 into the slots
and then rest the swathing deflector on the inside of side frame 27 and place plate 28 on
the outside; use screws 32 and nuts 33 to fasten everything into place.
Now use screws 23 and 26 to mount this group on plate carrier extension 19

16
Before assembling the rake arms, raise the protection frames and use hook 23 to hold
them up.
If the machine has to be set up for work, mount detachable arms 44 on to the fixed arms
45 and fasten them with pin 43; the two holes on the detachable arms are to adjust
swath width. The maximum working width is obtained by assembling the arm on the
innermost hole.
If the machine has to be prepared for transport or for storage, mount the detachable
arms in position (R) in holes (A) on the frame.

5) ADJUSTMENT, PREPARATION AND USE INTRODUCTION
Connection to the tractor is highly dangerous. Take great care and carry out the entire
operation in strict compliance with the following instruction.
Nobody should go near the area between the tractor and the machine.
Check that all warning and danger signs are in place and legible.
Check that the tractor is in good running order. Check the engine oil, gearbox oil, brake
fluid and cooling water levels as well as the tire pressures.
Refer to the tractor operator’s manual.
CONNECTION TO THE TRACTOR
The forage rake is equipped with 1st and 2nd grade coupling pins so that it can be
attached to any kind of tractor.
When assembling the forage rake, make sure that no one is standing between the
machine and the tractor.
Mount the lower tractor arms 3 to the machine coupling pins 2 and fasten them with
release pins 4. Mount the third point tie rod 5 with pin 6 and pin 7.
Remove pin 42 and raise rest foot 41 and fasten it up.
Before using the rear hydraulic system to raise the machine, make sure that the tractor
cab is closed. Raised side protections could hit something and cause damage.
The hydraulic system should be raised by adjusting the distribution valve, so that the
forage rake frame is lowered gently to the ground.

18
CONNECTING THE CARDAN SHAFT
More detailed information may be found in the Cardan shaft manual which, together with this
manual, is an essential part of the accident-prevention documentation.
It is your responsibility to read and comply with this documentation. If information given in
this manual should conflict with that given in the Cardan shaft manual, you should follow the
instructions given by the Cardan shaft manufacturer.
Fit the Cardan shaft and check that the
shaft is connected correctly both at the
tractor end and at the machine end. For
more details, see the descriptions on the
following pages.
If a safety system is provided, this should
be fitted to the machine end, not to the
tractor end.
During both transport and use, avoid
conditions where the Cardan
transmission shaft is extended to the
maximum. In all working conditions, the
telescopic tubes must overlap by at least
1/3 of their length (fig. 1).
Conversely, when the Cardan shaft is
contracted to the maximum, there should
still be a gap of approximately 50 mm
(2") (fig. 2).
Take particular care when connecting the two Cardan
shaft end forks and make sure that they are fully secured.
This is achieved by inserting the safety pins and bolts (1)
(Fig.3) in the special slots (2) on the power takeoff shafts
on both the tractor and machine ends.
Aloose shaft could come apart and cause considerable
mechanical damage and serious injury to persons.

19
DISASSEMBLY OF THE TRACTOR
In order to park the rake, make sure
that the ground beneath it is flat and
is able to bear the weight of the
machine.
When the rake is raised and lowered,
no one should be standing between
the tractor and the machine or near
the machine.
Extract the rest foot and fasten it
with pins 42 and 43.
Slowly lower the rake and make sure
it is resting firmly on the ground with
the third point released.
Switch off the tractor and put on the
brake before getting off the tractor.
Disconnect the cardan shaft and rest
it on its special support.
Disconnect the third point tie rod.
Disconnect the lower arms.
ADJUSTMENT OF THE FORAGE RAKE
The machine has to be adjusted when
it is attached to the tractor.
In order to adjust the rake, slowly
lower the rake so that the arms sway
and the roller under the drawbar rests
in the rack (see diagram A). Adjust
the third point tie rod so that the
rotor is lying horizontally or is tilting
slightly forwards and the tines are
slightly touching the ground.

20
Adjustment of work depth
Crank 25 adjust the work height and
adjustment depends on machine speed as
well as the quality of the product.
If adjustment is too high, the forage will
not be completely picked up and if it is
too low, the forage risks becoming dirty,
the grass will be damaged and the double
elastic tines will be worn down.
After having adjusted the work height of the tine,
adjustment height swathing deflector from the
ground using support 210.962 and 210.963.
(see spare parts list TABLE 920.139)
The distance between the swath-shaper plate
and the rotor determines the size of the
swath and on this depends the amount of
forage. Adjustment is continuous and a large
amount of forage means making a larger
adjustment.
In order to carry out adjustment, loosen lock
21 and screw 20 and then move plate carrier
27 to the required position and tighten first
screw 20 and then lock 21.
In the work position check that safety hook
13 fits into lock 10 in order to fasten the
swath-shaper plate into position.
Adjustment of gear speed and revs to work
the machine
The gear speed and machine revs depend on:
•the amount of forage
•the type of ground
•the degree of dryness
The forage rake was designed for a maximum number of revs for the power take-off of
540 g/min. We advise working with a rev number of 350-450 g/min.
The forage rake must never be used with a power take-off of 1000 g/min..
