4.6. THE LENGTH OF THE 3
RD
POINT
The adjustment of the third point is performed when the plough has been attached to the tractor. At
the same time the controlling of the work, loosening and lubrication are much more accessible
before the plough attachment.
Before joining the third point to the plough:
Vérifier la
bonne fixation du palonnier aux 2 bras inférieurs du tracteur.
S’assurer que les 2 vis du 3
ème point disposent de suffisamment de longueur de filetage (6) dans
les écrous centraux pour qu’il soit possible de les régler sans risque de déboitement ou
d’arrachement.
Examine if the cross-arm perfectly fastened to t
he tractor two bottom levers.
Be sure that two screws of the thir
d point are long enough (6) for the central female screws in
order not to damage or tear them off during adju
s
tment
It must be examined that two edge screw are on the same adjusting level.
Two seen threads (6) should be the same length (Z = T). So being maximum screwed the third point
must be the shortest. Or vise versa if it is unscrewed it must be maximum long.
NOTICE : Inside the third point the big quantity of the lubricant can obstacle the shortening. On some
tractors the lubricant must be cleared away with the dismounting of the lubricator which release the
lubricants being under the pressure.
