2.
Retract the piston-rods of the rollers into the maximum top position (piston-rods are drawn in) so
that the spacer rings placed on the piston-rods are compressed tightly. Place the machine in the
tractor suspension on the ground. Set the longitudinal plane of the machine by adjusting the
position of the bottom arms of the tractor and the drawbar of the third point of the tractor, thus
ensuring the same working depth for both disc rows.
10.2 Adjusting the longitudinal plane of the machine
• The machine is very stable at work; however, when the longitudinal plane is not set properly, the
machine may swing to the sides excessively. This effect may be removed by a proper setting of the
longitudinal plane of the machine using the drawbar of the third point of the tractor suspension so that
both the front and the rear row of discs work in the same depth.
Setting the longitudinal plane of the machine
1 – Third point drawbar – setting the longitudinal plane
When the machine swings to the left, the front disc row is recessed more.
Lift the front row by extending the drawbar of the third point of the tractor suspension.
When the machine swings to the right, the rear disc row is recessed more.
Recess the front row by shortening the drawbar of the third point of the tractor suspension.
