same time ensuring that there is always a safety
clearance (M) of 1-2 cm (1/2"-1") (fig. 3 page 12),
- position the chain stroke limiters (E) as shown in
photo 26, 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.
Chain stroke limiters :
For the combination of the EL 131 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
Bump stops :
Assemble bump stops (K) (photo 24) with the self-locking nuts provided. In the transport position, rear PTO shaft
must be disconnected and chain stroke limiters (E) (photo 26) removed. This will allow lower lift arms to rest against
the bump stops, 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 26).
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 26.
d) Maintenance of the linkage
Periodically grease the different pivot points equipped with 8 grease nipples.
When parking the combined unit ( EL 131 / 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 24) which rotates at the same speed as the tractor
PTO. This rear shaft should not be used with gears disengaged (neutral position) when driving a
secondary implement (seed drill etc.) as this could damage the gearbox due to a lack of lubrication. The
rear PTO shaft is 1 3/8" 6 spline profile and must not be used to transmit more than 37 kW (50 hp).
