SAFETY GUARDS
The safety guards protect against accidents and therefore ensure maximum machine safety
Figures 1, 3, 7, 11 and 15 (pages 10, 11 and 12) indicate the guards factory setting for category 1N (narrow lower
link spacing) and category "O" attachments with the head stock in the central position
This setting provides the optimal guarding whatever the machine width, hitch category and head stock position
When using a tractor with a category 1 linkage or when coupling to a machine with the head stock in the offset
position, the guards may also be fitted as shown in figures 2, 4, 5, 6, 8, 9, 10, 12, 13, 14, 16 , 17 and 18 to increase
clearance around the lower link brackets
However, on no account must the clearance between guards and lower attachment yokes exceed
60 mm / 2.3" (see distance D in figure 7). Lateral guard su ort (A and B in figure 7) must always remain
fitted.
Note : - When mounting the EL 35 - 130 headstock in the offset position remove guard (C, figure 12) and replace
it with bracket (E) supplied with the machine as shown in figure 14
- A third angle iron (F), also supplied with the machine, must be installed as shown in figures 13 and 17
whenever the EL 35 - 130 or EL 35 - 155 is attached in the offset position to a category 1 N or category
"0" tractor

OFF-SETTING
(fig. 19) (only for 105 / 117 / 130 / 155)
The EL 35 Power Tiller can be mounted behind a tractor in an off-set position to the right (or in line with the tractor)
The setting of the machine in this position should be carried out before mounting to the tractor
The offset position is obtained by removing the head stock (1) from its central position (A) and mounting it in position
(B) To avoid accidents, make sure the power tiller is properly secured before removing the head stock Use a
hoist, lifting from the tube Avoid using makeshift props that are unsafe
Position A : in line Position B : 18 cm (7") off-set to the right by distance "D"
After reassembling the head stock, make sure the front safety guards are correctly fitted (see pages 10, 11 and
12)
Note : The POWER TILLER EL 35 ty e 92 cannot be off-set by moving the hitch frame but it is possible to obtain
adjustment of 6 to 8 cm (2 to 3 ins) by adjusting the lower link brackets
When reassembling, make sure all bolts (V and
W) are tightened to a torque of 14 daNm
(100 ft.lbs)

- 14 -
FITTING TO THE TRACTOR
The EL 35 has two adjustment settings giving the following attachment possibilities :
The lower link brackets are mounted symmetrically to the head stock
*

- 15 -
P.T.O. DRIVE SHAFT
Make sure the EL 35 is resting on the ground and is maintained in a stable position with the parking stand or with
the front wheels Clean and lubricate the gearbox input shaft and slide the mating PTO shaft yoke in place
After mounting the Power Tiller, stabilize the tractor 3-point linkage with whatever means are recommended (tie
bars, chains etc )
Be sure the tractor P T O shaft drive is disengaged and stop engine
Couple the PTO shaft to the tractor P T O stub
Attachment is correct when machine is horizontal in work position
With the machine resting on the ground, adjust the top link (P) length to a position where the tractor PTO stub
and the tiller input shaft are parallel
In working osition :
- 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 23)

- 16 -
With the machine fully raised on the tractor hydraulic linkage :
- The 2 sliding tubes must not completely overlap each other ; a gap (M) of 1 cm (3/8") should exist between end
of sliding tube and yoke
- Both U joints (K) should operate approximately at the same bent angles which must never exceed
40° (figure 23)
Should the above mentioned conditions not exist :
- Shorten both tubes by an equal length, chamfer edges and grease liberally before refitting
- To avoid noisy running of the PTO shaft when lifting the machine out of work, attach top link (P) so that it is
almost parallel to the lower links (fig 23)
Im ortant : Always disconnect the tractor PTO drive before lifting the machine into the transport position,
otherwise permanent damage can be caused to the transmission shaft
Repeat these adjustments each time the machine is mounted to a different tractor
A safety chain (C) is delivered with the machine to
support the PTO shaft (T) when the machine is
parked This prevents the PTO shaft from becoming
soiled or deteriorated when in contact with the ground
Attach the chain (C) to the support (U) as shown in the
photo 24 opposite
Always make sure the PTO shaft guards are in good condition and secured with the safety chains
provided to prevent them from turning The safety chains should be attached to the side of the
machine at the safety guard of the central gearbox (photo 24) Replace guards immediately if they
become damaged

- 17 -
ROTOR SPEED
The rotor speed of the EL 35 is 248 rpm with a P T O speed of 540 rpm
No other PTO speed is allowed
USE
BEFORE ADJUSTING, MAINTAINING OR REPAIRING THE MACHINE, TURN OFF THE
ENGINE, REMOVE IGNITION KEY AND WAIT UNTIL ALL MOVING PARTS HAVE COME TO
A COMPLETE STOP.
The tilth varies with the work required The degree of tilth is governed by combining the following factors :
- rear shield position, regulated by suspension chain,
- forward speed,
- working depth,
- mounting of 2 or 3 pairs of blades,
- number of passes
Coarse tilth :
- Rear shield up
- Fast forward speed (approx 2 5 mph - 4 km/h)
- 2 pairs of blades
Fine tilth :
- Rear shield down
- Slow forward speed (approx 1 mph - 1 5 km/h)
- 3 pairs of blades

- 18 -
Hi ts o use :
- Allow the rotor to rotate at ist working speed before engaging it into the soil Gradually lower the machine while
pulling forward with the tractor
- Always work in a straight line When turning, lift machine out of work
- Never work in reverse, otherwise damage could occur to some component parts
- Do not disengage the PTO drive unless the machine has been lifted out of work
Importa t remarks :
Like many farm machines, the use of the EL 35 entails limits which must be respected in all situations
These limits are often tied in with :
- meteorological conditions : avoid working during and immediately after rainfall, wait until ground to be
worked is completely drained,
- soil ty es : smooth clods indicate too malleable or too humid soil to be worked in Wait until ground is
completely drained Soil consistency is ideal when clods crumble without sticking,
- tractor ower : adapt share depth, working depth and forward speed to power available and type of work
to be done
Never exceed the maximum allowable tractor DIN power : 26 kW (35 hp)
