PROBLEMS
Seeds on surface.
Seeds too deep.
Irregular seed drilling
depth.
The seed furrow remains
open and the seeds un-
covered.
The gearbox chain jumps
off the gears.
Irregular distribution of
chemical products
(Fertilizers and Micro-
granulates)
Row marker does not
work or works irregular-
ly.
cod. G19503270
CAUSES
1) Wrong seeding depth setting.
2) Obstructed seed delivery tube.
3) Insufficient pressure of the rear seed-
covering wheels.
4) Rear seed-covering wheels not suitable for
the ground.
5) Use of stainless steel seed-covering wheel
on damp soil.
6) Ground not suitably prepared.
7) Bent planting unit frame (example: caused
by knocks from stones on the ground).
8) Seed drilling on steeply sloping ground.
1) Wrong seeding depth setting.
2) Excessive pressure of the rear seed-cove-
ring wheels.
3) Unsuitable rear seed-covering wheels.
Clod clearer set too low.
1) Rear seed-covering wheels a long way from
the seed furrow.
2) Insufficient pressure of the rear seed-
covering wheels.
3) Rear seed-covering wheels not suitable for
the ground.
The two pinion axles are not parallel to each
other.
1) Wrong setting of the MINIMAX distributor
and/or gear ratios.
2) Product with specifi c gravity different to
those indicated in the table.
3) Use of non-granulated product (dusty).
4) Delivery tube bent sharply and/or blocked
by deposits.
5) Obstructed furrower element.
6) Distributor dirty with deposits.
7) Protective grille fi tted the wrong way round
(after maintenance).
8) Fertilizer on surface.
1) Impurities present in the hydraulic system.
2) The row marker arms rise too quickly (da-
mage to the structure).
USE AND MAINTENANCE
1) Correct the depth setting.
2) Cleaning
3) Increase the pressure of the rear wheels on
the ground.
4) Replace
5) Disable the stainless steel seed-covering
wheel.
6) Prepare the ground carefully.
7) Restore the planting unit frame.
8) Regular seed drilling is not guaranteed for
slopes greater than 20%.
1) Correct the depth setting.
2) Reduce the pressure of the rear wheels on
the ground.
3) Replace
Raise the clod clearer: it must be set as
shown in the instruction booklet.
1) Adjust the distance between wheels.
2) Increase the pressure of the rear wheels on
the ground.
3) Replace
Loosen the 3 axle fi xing bolts and adjust the
position of the axle support.
1) See distribution table and correct.
2) Protract the values of the table to the new
specifi c gravity.
3) Dusty products are not suitable for this type
of distribution. Change product.
4) Check the length, shorten them and
straighten them. Cleaning.
5) Cleaning
6) Cleaning
7) Check the position (a gap of about 1 cm
must remain on the back).
8) Increase the penetration power of the disc
and ballast the seed drill frame.
1) Clean the exchange valve and the nipple
with calibrated hole fi tted on the hydraulic
cylinders of the row marker arms (where
present).
2) Work on the fl ow regulators to correctly set
the system during the upward movement of
the row marker arms.
