3.13 Adjustment of the pre-implements
3.13.1 System Crossboard, System Agrilla
Figure 3.30
The pre-implements are normally preadjusted at the factory.
Similar to the lifting system, the pre-implements are also connected to a master and slave system.
Prior to adjusting the pre-implements, bleed and reset the hydraulic system in the same was as the
lifting system. See ”
3.10 Hydraulic adjustment of sowing depth (option 15582-)” on page 31
.
Bleeding the system should be done with the drill in the work position and the pre-implements
completely raised to enable the hydraulic rams to extend fully to the outermost positions.
Then verify the basic adjustment of the pre-implements while hitched to the tractor and the drill
folded out, resting on the seed boxes on level ground. If necessary, adjust the piston rods (A) to
achieve the same working angle on all pre-implements. Loosen the counter-nut (B) while turning
the piston rod and the hydraulic ram in place. The piston rods can be adjusted to a maximum ex-
tension of the thread (C) to 20 mm.
Fine adjustment is then performed in the field by adjusting the piston rods (A) until all sections
work at the same depth. Adjust the angle of the front pre-implement in relation to that of the rear
implement using the hole series in the parallel iron bar (D).
NOTE! Always make sure that the par-
allel iron bars do not interfere with the frame once adjustment is completed.
System Agrilla serial number 15432-
The pre-implement is connected to an individual Master and Slave system like System Disc. Ad-
justments are made in the same way as System Disc, see ”
3.13.2 System Disc” on page 37
