GUARDS

1) Front safety guards

The safety guards increase the safety of the machine.
The 2 front safety guards (P) are made up of 3 parts,
one fixed and 2 sliding sections. They are factory
fitted as shown on photo 1.
The sliding sections of the safety guards may need to
be repositioned (front wheels, track eradicators…).
Whatever the accessories the machine is equipped
with, the guards must remain fixed and cover the
whole length of the machine from the outside of the
adjustable lower link brackets (C) (photo 1).

2) Side safety guards

To reduce the machine width for road transport, proceed as follows :

- loosen the screws (A) of guards (B) (photos 2 and 3)

- pivot guards (B) upwards (photos 2 and 3),

- tighten screws (A).

1

2

4

Side guards (B) are safety
elements, they must be always
folded downwards at work (pho­tos 4 and 5).

3) Guard extension

Fit the guard extension (1) over the sheet metal guard
(2) of the torque limiter (see photo 6).

FITTING TO THE TRACTOR

The EL 142 can be fitted to all tractors equipped with
a standard Cat. 2 or Cat. 3 three-point hitch (figure 7).

Category "2"

- original equipment

Alternative attachment :
Category “ 3 N ”

(with a cat.2 space between lower lift arms)

Recommended with a EL 142/seed drill combina­tion.

The top hitch pin (code 525 970 00) and the lower hitch
pins cat.3 (code 525 925 00) are available through the
Kuhn Service Parts Department.

7

Note : The top link pin (B) has an anti-turn arm (T). It

should be fitted as shown in photo 8.

The lower attachment yokes can be placed in 2
different positions on the main frame.

1) Towards the rear (A) (photo 9) (original fitting) : to

bring the centre of gravity of the machine as close to
the tractor as possible (in combination with a seed
drill for example).

7A

8

2) Towards the front (B) (photo 9) : to avoid any

clashing with the tractor wheels when fitting certain
equipments such as front gauge wheels or track
eradicators.

P.T.O. DRIVE SHAFT

10

Make sure the EL 142 is resting on the ground and is maintained in a stable position. Clean and lubricate the
gearbox input shaft and slide the mating PTO shaft yoke in place. Before attaching the PTO shaft to the slip clutch
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
a torque setting of 10 daNm (75 ft.lbs) at the same time making sure that the flange is centrally seated.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.
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 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 :

- 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°

(fig. 10).

Should the above mentioned conditions not exist :

- Shorten both tubes by an equal length (fig. A and B), chamfer edges (fig. C) and grease liberally (fig. D) 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. 10).

Important : 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.

- 14 -

A

B

C

A hook (C) is supplied with the machine to support
the PTO shaft (T) when disconnected to avoid
damage or deterioration due to contact with the
ground (photo 11).

To avoid accidents which could be serious, make sure that the guards are always
correctly in place and secured with the safety chains. On the machine side, attach
restraining chain (H) to the corresponding hole on the right side of the hitch frame (photo

11). All worn or damaged guards must be replaced immediately.

- 15 -

FRICTION SLIP CLUTCH

The EL 142 is factory equipped with an adjustable friction slip clutch.
Spring pressure is factory pre-set (L = 32 mm / 1 1/4") for 103 kW (140 hp) tractors at 1000 rpm (min-1) PTO (photo

12).

The theoretical average length of springs (R) (L = 32 mm / 1 1/4") is only an indication and can be slightly modified
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

necessary and wait until the temperature of the clutch drops to a normal work temperature of
approximately 40°C (104 °F) before getting back to work. If the clutch overheats it will slip more
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
off the 6 springs (R) by unscrewing their securing nuts, let the friction plates slip for a few seconds then retighten
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.

- 16 -

ROTOR SPEED (ROTATIONAL FREQUENCY)

The EL 142 is fitted with a speed gearbox which adapt the rotor speed (rotational frequency) to the working
conditions.
To change the PTO speed (rotational frequency) invert or replace the sets of matching gearwheels located at the
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

- remove bolts (U) from cover plate (V) and pull the cover and gearwheel assembly out of the gearbox (photo 13),

- invert the set of matching gears (A and B) or replace it by the set (C and D), according to the desired rotor speed

(rotational frequency) (photo 14),

- always store the non used set of matching gears inside the gearbox by placing gearwheel (D) on the rear PTO

shaft and gearwheel (C) on the cover plate (photo 14),

- reinstall the cover plate making sure to position the O-ring (E) in its groove correctly (photo 14).

The gearbox is factory fitted with a rear PTO shaft (S) which rotates at the same speed (rotational frequency) as
the tractor PTO shaft (photo 16). An extra implement can be driven by a secondary PTO shaft which should be
assembled and used according to the legislation in force at the time.
Remove the PTO shaft cover (O) (photos 15 and 16). The rear PTO shaft is 1 3/8" 6 spline profile, and must not

be used to transmit more than 37 kW (50 hp).

If the rear PTO shaft is not used, always put cover (O) in place (photo 15).

- 18 -

ADJUSTMENT OF THE REAR HOOD

The rear hood unit consists of:

- Hood (Q) the position of which can be adjusted by

cranked handles (P) (photo 17)

- Flap (R) which can be adjusted and locked by

inserting pins (B) into holes (S) (photos 18 and 19)

The desired tilth can be obtained by adjusting the
position of rear hood (Q):

- lowering the hood increases the working of the

ground (see arrow C, figure 20) giving a finer tilth

- raising the hood reduces the working of the ground

giving a coarser tilth (figure 21).

17

18

Flap (R) must always be set to ensure that it levels the ground according to the flow of soil behind the rotor (figures
20 and 21). In order to keep the machine stable it is essential that the ground is well levelled in front of the roller.
If the flap is not correctly adjusted the ground surface will be undulating which can result in the machine pitching
or rolling in work, especially when travelling fast.

USE

Before carrying out any operation on the machine, stop the tractor engine,
remove ignition key and wait for all rotating parts to stop before leaving the tractor.

Clod size should be different depending on the job to be done.
The following features determine clod size :

- Choice of rotor (either POWER TILLLER, CULTITILLER or CULTIPLOW)

- Rotor speed (rotational frequency)

- Working depth

- Hood position.

- Position of the flap.

- Forward speed.

- Number of passes.

The rear hood/flap unit must be set to ensure that there is no risk of it touching the roller
during work.

To obtain fine clods :

- High rotor speed (rotational frequency)

- Hood (Q) lowered (figure 20, page 19)

- Set the position of flap (R) in relation to the working depth to ensure that it performs its function of levelling (figure

20, page 19)

- Low forward speed

- Choice of the rotor in accordance with given work conditions :

. CULTITILLER rotor with angled blades
. CULTIPLOW rotor with curved blades : a greater shattering effect to get even finer clods.
. POWER TILLER rotor with "three pairs of blades per flange".

To obtain coarser clods :

- Low rotor speed (rotational frequency)

- Hood (Q) raised (figure 21, page 19)

- Set the position of flap (R) in relation to the working depth to ensure that it performs its function of levelling (figure

21, page 19)

- Higher forward speed

- Choice of the rotor in accordance with given work conditions (CULTITILLER, CULTIPLOW or POWER TILLER

with "2 pairs of blades per flange").

EL 142 CULTITILLER or CULTIPLOW

With the EL 142 CULTITILLER or CULTIPLOW, clods are shattered vertically without modifying their natural
structure : not too many clods, nor too much fine soil !
Points are spirally mounted, working and aerating the ground over the entire rotor width ; no panning. They engage
into the ground with a digging action without risk of gathering up vegetable residue. The angle at which the blades
of the CULTITILLER rotor enter the ground has the effect of a pickaxe. The “trailing” position of the blades in
CULTIPLOW version eliminates nearly all risks of clogging and building up of plant residues.
The roller controls working depth and levels and packs the seedbed behind the machine.

The EL 142 CULTITILLER or CULTIPLOW is a very versatile machine offering a wide range of appli­cations :

- turning in stubble

- soil preparation after ploughing

- and in some cases, direct soil preparation without ploughing.

- 20 -

EL 142 POWER TILLER

The POWER TILLER rotor fitted with mulch blades "BH" is world renown for its excellent incorporation of organic
matter into the ground.
The POWER TILLER rotor can be equipped with either 2 or 3 spades, depending on the soil profile required. When
it comes to turning in stubble and reclaiming old pastures, the Power Tiller rotor is at it’s best.

The Power Tiller rotor fitted with mulch blades "BH" is recommended for :

- turning in green manure, dung, harvest residues

- reclaiming old pastures

- orchard maintenance

- turning in stubble

- market gardening.

Note : Before working in vegetable residue, an independant shredder must be used first to obtain a fine

shred and even distribution of residue so that it can then be easily incorporated into the ground, getting
a good mix. The more residue there is, the more important this is.

Hints on 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.

Important remarks :

Like many farm machines, use of the EL 142 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 types : 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 power : adapt working depth, forward speed and rotor speed (rotational frequency) to power available

and type of work to be done. Never exceed the maximum allowable tractor DIN power : 103 kW (140 hp).

- hood adjustment : The machine should not be operated with the hood (Q) (photo 17, page 19) completely

closed. The hood should always be sufficiently open so that worked ground can flow out freely. If the rotor is
operating deep down in the soil and the hood is closed, the large amount of worked ground could clog the rotor
and deteriorate the hoods.

EQUIPMENT

1) ROLLERS

The operator may choose to equip the EL 142 with :

- either a packer roller (studs welded onto a cylinder),

- either a packer roller PK2 (studs welded onto a cylinder) (only for EL 142 - 3,00 m),

- either a maxipacker roller (rows of discontinuous studs welded on a large diameter cylinder),

- either a crumbler roller (welded tubes and removable bars)

- or a maxicrumbler roller (welded tubes).

The roller :

- adjusts and controls rotor working depth

- packs the ground behind the rotor to create an ideal seedbed

- increases crumbling efficiency by breaking down the clods

- improves ground levelling.

Adjusting the roller (photo 23)

Adjustment in direction of travel :

The roller can be placed in six different horizontal
positions so that the overhang is reduced to a mini­mum in relation to the hood. This shift is carried out
with the 3 screws (C) on the multi-hole arms (A) and
plates (B) (photo 23).

23

Height adjustment :

The roller height is adjusted at (P) (photo 23).
To adjust, proceed as follows:

- Lift the machine behind the tractor,

- Place pin (T) in the hole corresponding to the required height (photo 23). Make sure that the same hole is used

on each side of the machine.

To limit the roller downward movement when manoeuvring on field end, a 2nd pin (T) may be ordered under part
number 517 070 00 (2 x) and be inserted in holes (O) of the adjustment plate (P) (photo 23). Do not restrain the
roller movement if the machine is equipped with a Venta seed drill resting on the roller arms.

To raise the roller completely out of work, lift the roller, then place the original pins (T) in holes (O).

Fitting of the adjustment sectors and roller arm mounting brackets (photo 23)

Fit the adjustment sectors (P) on the side plates using 8 cup square bolts (I) (M12 x35) and 8 self-locking nuts (M

12) (screw heads positioned on the inner side of the side plates).

Fit the roller arm mounting brackets (K) on the side plates using 4 hexagonal screws (M) (M 12x35) and 4 self­locking nuts (M 12).

- 22 -

A) STANDARD PACKER ROLLER AND PACKER ROLLER PK2 :

- EL 142 - 2.50 m : Kit No.121 6650 (standard)

- EL 142 - 3.00 m : Kit No.121 6600 (standard), Kit No. 121 7080 (PK2)

This rollers are particularly intended for use in wet or sticky soils. Efficient packing, proper levelling and good
crumbling are always achieved. Mud scrapers are an integral part of the standard packer roller and of the packer
roller PK2. These scrapers, placed between the rows of studs, ensure that the roller is cleaned.

a) Assembly of the packer rollers and their scrapers

When assembling the roller, take particular care concerning the direction of rotation. The direction of rotation is
indicated on the decal affixed to the side of the roller (see arrow, figure 24).
Using 8 bolts (U) and M 12 nuts and mount roller arms (B) and scraper bar arms (D) on the bearing housings (T)
placing spacer (N) as shown on drawings 24 and 25 (torque 10 daNm / 74 ft.lbs).
Then fit the swinging arms (A) on roller arms (B) with 6 bolts (C) and M16 nuts using the 3 holes (C) (torque 22
daNm / 160 ft.lbs) (fig. 26).
Then bolt the scraper bar (H) onto holders (D) using the 4 screws (R) (figure 24). Do not fully tighten these bolts
at this stage. Check that all the cleaners (P) of the scraper are in the retracted position.
Position the 2 eybolts (Q) (photo 27). Using the two nuts (S) tighten against the tensioners to pivot the scraper
towards the roller until the two elongated holes almost butt out (photo 27). Thereafter tighten the four bolts (R) and
adjust the scraper plates (P) as described below (torque 22 daNm / 160 ft.lbs).
Then mount the complete roller assembly with arms (A) on the roller arm brackets (K) by means of 2 pins (X)
secured with 2 self-locking screws (J) (M10 x 16) (photo 23, page 22).

- 23 -

b) Adjusting scraper plates

- Slightly loosen fixing bolts (V) of the scrapers (P) so that they slide freely (figure 24, page 23).

- Check that their position is central relative to the rows of roller teeth. The scraper supports have elongated holes

to allow readjustment if necessary.

- After having checked that the scraper bar is in its furthest forward position (photo 27, page 23), position scraper

plates one at a time so that they are all in contact with the roller. Retighten bolts (V) to 8 daNm / 50 ft.lbs (figure
24, page 23). Make sure that the plates only lightly touch the roller and do not interfere with its rotation.

c) Cleaning the scrapers

In case of crop or soil build-up, to clean, it is recommended that the scraper assembly be pivoted to the rear around
the two upper bolts (R) (photo 27, page 23).

- Loosen the self-locking nuts (S) (photo 27, page 23).

- Release the two eyebolts (Q).

- Remove the two lower bolts (R) (photo 27, page 23).

- To facilitate pivoting the scraper assembly, use a lever in each of the two holes (L) situated at each end of the

connecting tube (H) (photo 27, page 23).

B) MAXIPACKER ROLLER 2,50 m - Kit No. 121 6690

3,00 m - Kit No. 121 6700

This roller is suitable for all soil types and especially humid and sticky soils. It provides an efficient ground packing,
a good levelling and crumbling.
Due to its large diameter cylinder, it provides a large ground contact area, hence reduced sinking and less
resistance to rolling, meaning a reduced traction power is needed. The scraperbar is part of the maxipacker roller.
The scraper plates located between the rows of studs ensure the cleaning of the roller. They are hard coated to
further increase their service life.
In case of blocking with crop residues, the scraper bar can be easily pivoted to permit cleaning.

a) Fitting the maxipacker roller and its scraper (figures 28 and 29 and photo 30).
When fitting the roller, be sure to check its direction of rotation. The direction of rotation is indicated by a sticker

on the side of the roller (see arrow on figure 28).
Using 8 bolts (U) and M12 nuts and mount roller arms (B) and scraper bar arms (D) on the bearing housings (T)
placing spacer (N) as shown on drawings 24 and 25 (torque 10 daNm / 74 ft.lbs).
Then fit the swinging arms (A) on roller arms (B) with 6 bolts (C) and M16 nuts using the 3 holes (C) (torque 22
daNm / 160 ft.lbs) (fig. 26, page 23).
Then fit scraper supporting bar (H) onto the 2 support arms (D) with the 6 bolts (R). Do not tighten the bolts at this
stage (figure 28).

28

29

- 24 -

Fit the 2 adjusters (Q) (photo 30). Using the 2 nuts (S)
on the adjusters, bring the scraper bar towards the
roller until it is almost bottomed-out in the 2 slots of the
support arms (D) (photo 30). Then tighten the 6 bolts
(R) to a torque of 22 daNm / 160 ft.lbs, and if required
adjust the position of the scraper plates (P) as shown
thereafter.
Then mount the complete roller assembly with arms
(A) on the roller arm brackets (K) by means of 2 pins
(X) secured with 2 self-locking screws (J) (M10 x 16)
(photo 23, page 22).

b) Adjusting the scraper plates

- The hard coated thick scraper plates have been factory

pre-set on a reference roller. Therefore, they are nearly
in the correct working position after mounting the scraper
bar (paragraph a, page 24).

- If necessary, adjust the scraper plates so that they are in

contact with the roller and tighten the screws (torque 8

daNm / 50 ft.lbs). Make sure that the scraper plates
only lightly touch the roller and do not interfere with
its rotation.

- Also make sure that the scraper plates (P) are well

centred with regards to the stud rows (E) (photo 31). The
scraper plate supports (S) are equipped with oblong
holes enabling to recentre them by sliding them cross­wise at the screw level (V) (torque 10 daNm / 74 ft.lbs).

30

c) Cleaning the scrapers

In case of crop residue build-up, it is recommended for cleaning that the scraper be pivoted backwards around
the 2 upper bolt holes (R) (figure 28, page 24). To do this, untighten the 4 lower bolts (R) and release the 2 adjusters
(Q) after loosening their self-locking nuts (S) (photo 30).
To ease pivoting of the scraper bar towards the rear, use a lever in holes (L) (photo 30) placed at each side of the
scraper bar (H).

31

C) CRUMBLER ROLLER : 2,50 m - Kit No. 121 6670

3,00 m - Kit No. 121 6680

The crumbler roller is ideal for dry and slightly humid conditions. It is made up of fixed welded tubes (F) and
removable bars (G), held in place by round support rings (figure 32, page 26).

With removable bars in place :

Recommended in dry conditions for fine tillage and levelling with good ground packing.

Without removable bars in place :

Recommended in more humid ground, less risk of roller clogging. Tillage and levelling are coarser.
Bars can be removed as follows :

- Remove inside roll pins

- loosen the bars using a hammer

- pull out the bars.

- 25 -

Using 8 bolts (U) and M12 nuts, mount the roller arms (B) together with the covers (D) on the roller bearing housings
(T) placing a spacer (N) as shown on drawings 32 and 33 (torque 10 daNm / 74 ft.lbs). Then fit the swinging arms
(A) on roller arms (B) with 6 bolts (C) and M16 nuts using the 3 holes (C) (torque 22 daNm / 160 ft.lbs) (fig. 26,
page 23).
Then mount the complete roller assembly with arms (A) on the roller arm brackets (K) by means of 2 pins (X)
secured with 2 self-locking screws (J) (M10 x 16) (photo 23, page 22).

32

D) MAXICRUMBLER ROLLER (photo 34)

2.50 m - Kit no. 121 6950

3.00 m - Kit no. 121 6870

The maxicrumbler roller is ideal for dry or slightly
humid conditions. It is not advisable to use it in
conjunction with an integrated seed drill.
It is made up of fixed tubes (F) welded on round
support rings (photo 34).

2) SKIDS + STAND (photos 35 and 35 A)

Kit no 120 9210

The EL 142 can be equipped with 2 skids which must be mounted on each side of the machine.
This equipment is recommended in Cultirotor version when no roller for working depth control is fitted.

Depth control is adjusted by means of 6 hole skid bars (T) (photo 35).
Assemble skids following photo 34. First remove the wear plate of the lateral housing.
A stand (E) is supplied with the skids to ensure stability when machine is parked (photo 35 A).

3)FRONT GAUGE WHEELS

(photo 36)

The EL 142 can be equipped with a gauge wheel kit.
Wheels (R) are fitted on cross tube (T) in front of the
machine. This equipment is recommended either in
Cultirotor version when no roller is fitted, or for all
versions combined with a roller in order to improve the
machine’s stability.
Wheels (R) can easily be adjusted in height inside
their supports using pins (B).
Handles (A) make it easier to handle the gauge
wheels (R).

Kit no 121 6640

36

NOTE : - When mounting the front wheels, slide guards (P) (photo 36) so that they cover the complete

front part of the machine located at the exterior of the 3-point frame’s mounting yokes (C). The
gap between guards (P) and the wheels columns (R) must be of less than 60 mm.

- In addition, on 230 and 250 models, dismount the front safety guard inner part on each side
of the headstock in order to obtain the space required to fit the front gauge wheels.

IMPORTANT NOTE CONCERNING THE USE OF
FRONT GAUGE WHEELS

When the EL 142 is used with front gauge wheels
combined with a roller, the tractor top link must be
connected to the oblong hole (O) on the machine’s 3­point frame (photo 37). With this method of hitching
the machine adapts freely to the ground contours,
independently of the tractor.

Coupling the top link to the oblong hole (O) on the machines headstock is only intended for
work. It is strictly forbidden to use this hole during transportation.

37

- 27 -

4) SIDE SEPARATING DISCS (photos 38 and 38A)

Kit no. 121 6630

These discs improve soil movement towards the rotor and thus achieve a better definition between worked and
unworked land. The side separating discs also help to stabilize the machine during surface work. Fit the side
separating discs (D) to the cross bar (T) as shown in photo 38. They are adjustable in height on the inside of their
supports (C) using pins (B).
They are also adjustable laterally. Make sure to set both side discs (D) in the same position.
Handles (A) make it easier to handle the side separating discs (D) and also act as a stop to prevent accidents.

At transport, in order to reduce the overall width, the side separating discs (D) must be
completely retracted into their supports (S) (see arrow) and locked in the holes (N) using the
pins (P) (photo 38A).

5) REAR WHEEL KIT (photos 39 and 40)

Kit no. 121 6360 for EL 142 - 2.50 m
Kit no. 121 6370 for EL 142 - 3.00 m

Rear wheels can be fitted in place of the roller for certain surface operations (for example, stubble clearing or
turning over pastures).
The rear wheel kit can be fitted in various positions (lengthways) on the roller arms (P) delivered with the kit by
means of 8 hexagon bolts (H) (M 16 x 55) and 8 self-locking nuts (M 16).
Next fit cross bar (Q) on the fixed arms (U) of the rear wheels using 2 hexagon bolts (V) (M 16 x 55), 2 hexagon
bolts (W) (M 16 x 55), 2 flat washers (X) (diameter 16 x 30 x 3) and 4 self-locking nuts (M 16). The cross bar can
be fitted either in the upper position (as shown on photos 39 and 40) or the lower position (when working with an
integrated seeder or separate seeding system). When fitting in the lower position use the 2 longer hexagon bolts
(W) (M 16 x 80) supplied.
Rear wheels (Y) should face inside the machine for transport to reduce machine width (photo 39). They should
face outside during work so as not to roll over the ground worked by the rotor (photo 40).
It may, however, be useful to work on field edges with the wheels in their transport position. In this case the wheel
scraper should be pivoted to the rear of the machine (seen in the forward direction).
To put the rear wheels into their transport position (photo 39) or work position (photo 40), pivot them inside or out
on vertical axle (F). Lock them in place using linchpin (Z), do not forget to insert washer (R) (diameter
23 x 54 x 6).

- 29 -

6) TRACK ERADICATORS

In order to reduce the tractor wheel marks left on the seedbed, the EL 142 may be equipped with wheel track
eradicators. Depending upon the working conditions and machine widths, various types of track eradicators may
be ordered : - Kit no. 121 6610 for the traction bolt overload mechanism

- Kit no. 121 6620 for the adjustable spring overload mechanism

The eradicator tine mounting yokes (C) are to be fitted on the cross tube (T) as shown on photos 41 and 41 A.
The height of the leg (L) with reversible share (F) can be adjusted according to the depth of the wheel tracks by
means of a pin (N) (photos 41 and 41 A). Nevertheless, the working depth of the shares must never

exceed 100 mm (4").

The track eradicators are equipped with an overload mechanism should they encounter an obstacle :

- with traction bolt (T) (photo 41) : breakage of the bolt (ref. 801 310 51) with its nut (ref. 802 010 30)

- with adjustable spring (U) (photo 41 A) : the tine clears the obstacle and regains automatically its position.
Recommended in difficult or stony grounds.

41

The track eradicators must be mounted centred with regards to the tractor wheels, one per wheel (photos 42
and 42 A). In the case of dual wheels or large tyres, additional track eradicator tines can be fitted (to be ordered
under n° 121 6610 or 121 6620).

41A

42A42

NOTE : - Track eradicators are only to be used for secondary tillage work.

- When mounting the track eradicators, slide guards (P) (photos 41 and 41 A) in order to cover
the complete front part of the machine located at the exterior of the 3-point frame’s mounting
yokes. The gap between guards (P) and the track eradicators must be of less than 60 mm.

7) 3-POINT LINKAGE WITH HYDRAULIC LIFT FOR ADDITIONAL IMPLEMENTS

(photo 43) Kit no. 121 6720

43

The 3-point linkage with hydraulic lift cylinders (V) reduces the overhang of a combination (EL 142 - seeder, for
example) by lifting back the combined machine over the EL 142 (see photo 45 on page 33).

a) Assembly :

The hydraulic lift linkage is fitted to the EL 142 by means of axle (Q) and pins (U) (photo 43). A spacer washer
(Ø 20 x 45 x 8) must be added on each side of the headstock mounting plates in order to minimise the lateral play
at (U).

Hydraulic cylinders (V) necessitate at least one single acting valve on the tractor.
Attach hydraulic hoses (K) to cross bar by means of 2 hose clamps (N) and connect hoses to the cylinders (V)
as shown in photo 43.

To allow adaptation of Category 1 and Category 2 implements, hooks (A) and spacers (B) can be assembled in
different ways : either to the inside or to the outside of rear frame (C) to obtain desired span.
The hooks (A) can also be adjusted in height (two positions). The locks (D) are used to secure the secondary
implement's lower link pins inside hooks (A) (photo 43 and fig. 44 on page 30).

- 31 -

44

In order to reduce combination overhang as much as possible, the 3-point frame lower linkage hooks (A) can be
adjusted horizontally through a range of 22 cm (8,5") (photo 43 on page 31).
Depending upon application, the standard position (as set in factory) can be changed. The alternative positions
can be achieved as follows :

- towards the rear : by combining the two rear positions of linkage arm (W) with the four holes (F) of arm (G) (photo
43 on page 31)

- towards the front : by first moving rear frame (C) into position (Y) and by combining the two front positions of
linkage arm (W) with the four holes (F) of arm (G) (photo 43 on page 31).

Note : In the position (Y), the 2 plates (Z) must be removed.

b) Combination with a machine with PTO drive

(for example a pneumatic seed drill - photo 45)

Set of two chain stroke limiters Kit no. 124 6040

For the combination of the EL 142 with a PTO powered
machine, it is necessary to fit a set of two chain

stroke limiters (E) available as an optional extra to
prevent the PTO shaft sliding tubes (T) from butting
together and to protect the PTO shaft from being
subject to excessive angles.

Proceed as follows when adapting the seeder for the
first time :

- Connect transmission (T),

- progressively lift the combined machine up to the
maximum overlap of the transmission tubes, at the
same time ensuring that there is always a safety
clearance (W) of 1-2 cm (1/2"-1"),

- position the chain stroke limiters (E) as shown in
photo 45, adjust tensioners (R) in order to prevent
the two cylinders (V) from lifting any higher.
The rear hydraulic linkage can then be operated with
total safety.

Bump stops :

45

In the transport position, rear PTO shaft must be disconnected and chain stroke limiters (E) (photo 45) removed.
This will allow lower lift arms to rest against the bump stops (M) (photo 43), preventing accidental over-raising and
damping vibrations which reduces loading on structural parts.

c) Safety chain

A safety chain (H) prevents the hydraulic lift linkage from lowering accidentally during
transport if, for example, there is an oil leak (see photo 45).

This safety chain (H) is supplied as standard with all the hydraulic lift linkages and must be connected to the chassis
(S) and the rear 3-point frame (C) with 2 pins (A) as shown on photo 45.

d) Maintenance of the linkage

Periodically grease the different pivot points equipped with 8 grease nipples.

When parking the combined unit (EL 142 / seed drill, for example) make sure that the
additional implement is lowered first.
Always put cover in place if the rear P.T.O. shaft is not used.

NOTE : All gearboxes are fitted with a rear PTO shaft (P) (photo 43) which rotates at the same speed (rotational

frequency) as the tractor PTO. The rear PTO shaft is 1 3/8" 6 spline profile and must not be used to
transmit more than 37 kW (50 hp).

There are two adhesive safety decals (O) and (O') on the 3-point frame as shown in photo 43, page 31. Their aim
is to contribute to your safety and the safety of the people working with you. Check their location and read them
carefully. Always keep the decals clean and legible ; replace them if they are not.

- Fixed adapter : Kit no. 121 6750

For assembling and operating instructions see the VENTA AL and TI instructions booklets.

9) SEMI-AUTOMATIC HITCH (photo A)

Kit no. 121 6770 - Category 2
Kit no. 121 6780 - Category 3

The semi-automatic linkage consists especially of a
cross-shaft (L), 2 linkage hooks (M) and 2 bushes (N).
The cross-shaft (L) should be fitted to the tractor lower
links, and the linkage hooks (M) should be fitted to the
machine chassis in place of the standard lower at­tachment brackets.
Do not forget to install the 2 spacers (N).

10)HARD COATED PLATES FOR STANDARD PACKER ROLLER AND

PACKER ROLLER PK2

These scraper plates, which are particularly resistant to wear and tear, are available as replacement parts under

part n° 525 600 10.

- 34 -

11) NYLON CLEANING PLATES FOR STANDARD PACKER ROLLER,

PACKER ROLLER PK2 AND MAXIPACKER ROLLER SCRAPERS

Part No. 525 702 00 for the standard packer roller and the packer roller PK2
Part no. 525 923 00 for the maxipacker roller

These cleaning plates are made from a supple synthetic
material which enables them to be slightly pre
compressed against the roller for improved cleaning
action.

a) Installation and adjustment (photo 46) :

The nylon cleaning craper plates (R) are to be placed :

- between two new standard steel scraper plates (S)
(525 321 30) for standard and PK2 packer rollers by
using a longer screw (V) (part No 500 073 00),

- between two non hardcoated steel scraper plates (S)
(525 989 10) on maxipacker rollers by using a longer
screw (V) (part No 800 312 40).

46

Allow the nylon cleaning plate (R) to stick out of the carrier plates (S) by 10 mm and press it slightly against the
roller so that its leading edge is in contact with the roller segment across its full width. Rotate the roller one complete
turn to check that there is no gap between roller and nylon cleaning plate. Re-adjust the plate if this is not the case.
Also check that the upper carrier plate is set parallel to the roller segment and does not come into contact with it.

b) Use :
The nylon cleaning plate is particularly recommended for light, loamy or chalky grounds with little crop residue or

stones. A correct cleaning plate adjustment results in a clean and shiny roller area across the full width of the
cleaning plates.
Soil deposit on the roller will result in premature cleaning plate wear. Readjust them quickly. The cleaning plate
is reversible for increased service life.

12) P.T.O. SHAFTS

c) CULTITILLER rotor with Fast-Fit blades

The CULTITILLER rotor is equipped with angled left
and right blades, solidly housed in individual supports
welded on the rotor tube (photos 58 and 58A).
Start fitting blades on the support nearest the side
gearbox. A left blade should be fitted first (cutting
edge facing the left in the forward direction [A]) (photo

58). Then fit a right blade on the support opposite the

left blade. Fit all blades like this, alternately left and
right The last blades fitted should be the one nearest
the right end shield.
The cutting edges of all blades should face the direc­tion of rotor rotation (F) (in forward direction [A])
(photo 58).
To facilitate the removal of the lynch pins (M), use the
special key (N) supplied with the machine (photo
58A).

End blades : The left end flange is fitted with 2 angled
blades and 2 left guard caps (B) (photo 58). The right
end flange is fitted with 2 right angled blades and 2
right guard caps. The blades must be fitted on the
flange inner side and the guard caps on the outer side
using 2 screws (M 16) (torque : 30 daNm/220 ft.lbs.).

58

When replacing blades, also change
guard caps (B) located on both rotor
end flanges (photo 58).

d) CULTIPLOW rotor with 2 bolts per blade

(photo 59)

This CULTIPLOW rotor is fitted with right and left
angled blades bolted onto flanges welded on the rotor
tube. To distinguish the left blades from the right
blades, note the cutting edge of the blade which is
facing towards the left in the rotor rotating direction
(F) (seen in the direction of travel (A) of the machine).
Each rotor flange is equipped with two left angled
blades and two right angled blades. On the end
flanges, 4 angled blades are mounted on the inner
sides.
On intermediate flanges the 2 right angled blades are
mounted on the right side and the 2 left angled blades
are mounted on the left side.
Fit all blades like this so that left and right blades are
fitted helicoidally.
The mounting bolts heads must be on the blade side,
the washers and bolts on the flange side.

58A

e) CULTIPLOW rotor with 1 bolt per blade

(photo 60)

This CULTIPLOW rotor is fitted with left and right
angled blades. To distinguish left blades from right
blades, refer to part number marked on the back of
each blade (K1631030 = left blade, K1631040 = right
blade).

Each rotor flange is equipped with 2 left angled blades
mounted in holders welded to the flange left face and
2 right angled blades mounted in holders welded to
the flange right face.
On the end flanges, all holders are welded on the inner
face of the flanges.
Make sure to place the end flange blades in such a
way that they continue the spiral formed by the other
blades.
To replace blades, slightly unscrew fixing nuts, re­move blades from holders, insert new blades and
tighten nuts.

Bolt torque : 30 daNm/220 ft.lbs.

When replacing blades, also replace
guard caps (C) located on both rotor
end flanges (photo 60).

- Remove the 9 special hexagonal bolts (M16 x 43)

and their conical spring washers at F (photo 61).

- Remove the 2 hexagonal bolts (T) (M16 x 55)

(photo 62).

- Lift the machine. The complete rotor with housing

(H) now separates from drive flange (E) and side
shield (J) (photo 62).

Fit an alternative rotor :

Install the rotor by following the disassembly proce­dure in reverse order.

- Tighten the 2 hexagonal screws (T) (M16 x 55) (photo

62) to a torque of 30 daNm (221 ft.lbs).

- On drive flange (E) side, assemble 9 special hex­agonal bolts (M16 x 43) and their conical spring
washers at F (photo 61). Tighten to a torque of 30
