Three-point linkage for secondary equipment
In order to allow installation of a secondary implement
in the shortest possible position, the attachment arms
are adjustable (
11/1
).
Fit the chains (
11/2
) and perforated rail (
11/3
) in such
a way that the catch hooks are low enough to allow
coupling - and to allow the implement to be raised
sufficiently.
The chains should be slightly slack during opera-
tion in order to allow the attached implement (e.g.
seed drill) to level itself independently relative to the
ground.
Secure the catch hooks with safety pins (
11/4
).
Adjust the position of the attached implement at the
turnbuckle (
11/5
, top link).
The cat.III catch hooks can be adapted to the clear-
ance given by cat.II by repositioning the headstock
and catch hooks further inside. Use bushes if the at-
tached implement is fitted with cat. II lower link pins.
To adjust to live power take-off operation, adjust the
height of the support (
11/6
) to prevent collisions with
the drive shaft.
Hydraulic ”Drill-Lift” three-point linkage
Use the hole positions (
12/1+2
) to adjust the attach-
ment clearance, keeping to the ”same hole” on each
side.
The catch hooks can be bolted onto the inside or out-
side (cat.ll or lll clearance).
Adjust the catch hooks to the correct position - (
12/3
).
The hooks can also be bolted on in a rearward-slop-
ing position to allow more room for attachment.
Attach safety devices once coupling is complete (
12/
4
).
Adjust the top link to the correct position at the turn-
buckle (
12/5
).
Secure the ”front-mounted” implement with chains
(
13/1
) for transport by road, close the shutoff valve
and ensure that the end-stop bolts (
13/2
) are in place
with the implement in this position.
A shaft-driven attached implement can only be oper-
ated with the drive shaft disengaged - see also ”Drill-
Lift restrictor” (optional extra).
The single-function tractor-mounted control device
for the ”Drill-Lift”
must always be set to ”float
” during
operation. – Set to ”Lower” as the attached implement
(seed drill) can align itself with the ground independ-
ently of the rotary harrow.

When advancing or raising the combina-
tion take care not to collide with any part
of the tractor (e.g. the open rear panel of
the cab).
