IMPORTANT:
¾ If we are not going to return to the field before changing the plough bottom angel adjustment,
check the wearing parts condition (gib heads and blades). The worn parts prevent the required
penetration. The gib heads should be pulled forward and blades should be changed.
¾ If plough bottoms penetrate too deep, it is difficult to pull the plough, the fuel consumption is
being increased, the securities will be disengaged, the ground will slip under the rear part of
the breast.
¾ The rear measured height (Y) must never be less than the front measured height. (X).
9.6.7. ADJUSTMENT OF JOINTERS
The task of the jointers is to cut plants to provide suitable rotation of the residues.
The height of the jointer can be adjusted (from top to bottom) and fron front to back direction.
9.6.7.1. Security pins on the jointers
The jointer is protected by shearing. At hitting the obstacle (stone) the upper pin (50) shears and the
sole of the jointer turns round the pin.(51) As standard equipment the shearing was calibrated to 80
kg (GB reference: VI 29 08).
We increase the security resistance, if the 100 kg calibrated pin (GB reference: VI 29 09) is used. The
suitable pins can be got from the GRÉGOIRE-BESSON dealer.
9.6.7.2. Adjustment of the jointer hieght
Generally it can be said that the front part of the jointer iron (46) should be adjusted so that it could
work in the half height of the soil (about 6 cm / 2’’1/2).
¾
In order to adjust the working depth of the jointer, two cusped screws (47) should be loosened so
as to be able to pull them out of the hole of the jointer arm (48)
¾
Push the jointer arm (48) into the holder (49) till you get the required height.
¾ Screw back two screws (47) paying attention that the jointer arms (48) go back into the hole.
¾ In order to put other jointers into the same level, perform the operation accordingly to the number
of the holes on the rear part of the jointer.
¾ The length of the standard jointers is (48) 330 mm ( ≈ 13’’). There are longer models (410 mm /
16’’) to use them for less deeper ploughing (Reference: 19 186).
N.B. :
¾ Changing the depth of the plough, the jointers adjusting should be corrected as well.
¾ If the jointer is adjusted too high, behind the jointer (and at the rear part of the plough bottom
around connecting link) there may be clogging as the plants will not be cut properly.
¾ If the jointer is adjusted too deep, there may be clogging in front part of the jointer which will not
be able to absorb too big quantity of the plant residues. At the same time the plough can be pulled
with bigger difficulty and the tractor will use more fuel.
¾ In both cases it is possible that the plant residues will not be rotated properly.
Think over this situation till the end before performing the adjusting the jointer.
¾ The modification of the adjustment start on one or two jointers, then test them. If the result is
suitable, adjust the other jointers. In the contrasting situation perform another adjustment.
