gearboxinputshaftandslidethematingPTOshaftyokeinplace.BeforeattachingthePTOshafttotheslipclutch
flange, it is essential that both mating surfaces are thoroughly cleaned.
Bring both components together and fix in place using the self-locking screws provided. Tighten all the studs to
atorquesettingof10daNm(75ft.lbs)atthesametimemakingsurethattheflangeiscentrallyseated.Tightness
has to be checked regularly.
After mounting the EL 142, stabilize the tractor 3-point linkage with whatever means are recommended i.e. the
bars, chains, etc.
Be sure the tractor P.T.O. shaft drive is disengaged and stop engine.
Couple the P.T.O. shaft to the tractor P.T.O stub.
Attachment is correct when machine is horizontal in work position.

In working position :
- The 2 angles (K) formed by the centre lines of the yoke and the sliding tubes must be equal and not exceed a
combined angle of 30° when working.
- The sliding tube overlap (L) must be at least 22 cm (8.5") (fig. 10).
With the machine fully raised on the tractor hydraulic linkage :
- The2 sliding tubes must not completely overlap each other ; a gap (M)of1cm(3/8")shouldexistbetweenend

FRICTION SLIP CLUTCH
The EL 142 is factory equipped with an adjustable friction slip clutch.
Springpressureisfactorypre-set(L=32mm/11/4")for103kW(140hp)tractorsat1000rpm(min-1)PTO(photo
12).
Thetheoreticalaveragelengthofsprings(R)(L=32mm/11/4")isonlyanindicationandcanbeslightlymodified
according to machine width, work conditions and tractor. Too light a spring pressure will allow the plates to slip
continuously or intermittently at frequent intervals, resulting in overheating and rapid wear of the friction plates.
On the other hand, over pressured or completely coil bound springs will provide no protection to the drive
components (this occurs at 31 mm spring length).
IMPORTANT : * Always check if the clutch is set correctly for the work to be carried out. It should feel warm
to the touch during work.
* If the clutch slips excessively (too light a spring pressure, obstacles, etc.), readjust if
necessaryand wait until thetemperatureoftheclutchdropstoanormal work temperature of
approximately40°C(104°F)beforegettingbacktowork. Iftheclutchoverheatsitwillslipmore
easily, thus increasing disc wear.
* With L = 31 mm the springs (R) will be completely coil bound and the clutch cannot operate.
Never work with springs fully locked as this risks deteriorating drive line components if an
obstruction jams the rotor. Always loosen at least half a turn.
NEVER FULLY LOCK THE SPRINGS.
Check clutch setting regularly, especially after the machine hasn’t worked for a long time. Completely slacken
offthe 6 springs (R)byunscrewing their securingnuts,let the frictionplatesslip for afew secondsthenretighten
springs as explained above (to L = 32 mm / 1 1/4").
Note : We recommend that the clutch guard be removed for easier access when carrying out slip clutch
adjustments. Don’t forget to bolt guard back in place after adjustments have been made.

ROTOR SPEED (ROTATIONAL FREQUENCY)
The EL 142 is fitted with a speed gearbox which adapt the rotor speed (rotational frequency) to the working
conditions.
TochangethePTOspeed(rotationalfrequency)invertorreplacethesetsofmatchinggearwheelslocatedatthe
rear of the gearbox. The machine is standard equipped with 2 sets of gearwheels.
To invert the pinions proceed as follows. Tilt the machine forward to avoid oil leaking out of the gearbox when
removing the cover.
To do this :
- uncouple the PTO shaft
- shorten the turn buckle
- raise the machine in order to obtain a satisfactory angle
-removebolts(U)fromcoverplate(V)andpullthecoverandgearwheelassemblyoutofthegearbox(photo13),
- invertthesetofmatchinggears(AandB)orreplaceitbytheset(CandD),accordingtothedesiredrotorspeed
