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 :
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.
