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.
