ADJUSTMENTS
6.10.1 ADJUSTING TRACK MARKER’S
LENGTH
Track marker’s arms are extensible. To calculate the horizon-
tal spacing BETWEEN TRACK DISCS AND THE LAST METE-
RING UNIT (B, Fig. 55), use following formula:
Fig. 55
B
= [
A
x (
NUMBER OF ROWS
+
1
) -
C
] /
2
WHERE
:
A
= row spacing
B
= horizontal distance between track disc and the
last metering unit.
C
= track width of the tractor.
DISTANCE B CALCULATED USING THIS FORMU-
LA IS THE ADJUSTING LENGTH UNTIL THE CEN-
TER OF THE TRACTOR’S LEFT WHEEL (FIG. 55).
PERFORM THE CALCULATION WITH ALL MEA-
SUREMENTS IN CENTIMETRES.
The distance of the track marker’s disk can be adjusted fo-
llowing these steps:
Fig. 56
1
1- Loosen the two securing screws (1, Fig. 56).
2- Place the track disc at the distance B previously calculated
(B= distance between the track disc and the last metering
unit which is closer to the track marker).
3- Retighten the 2 securing screws (1, Fig. 56).
6.10.2 ADJUSTING TRACK DISC’S ORIEN-
TATION
To adjust the track disc’s orientation, follow these steps:
Fig. 57
2
1-
Loosen the securing screw (2, Fig. 57).
2-
Adjust track disc’s orientation so that the it has the desira-
ble impact on the ground.
3-
Retighten the screw (2, Fig. 57).
IT IS NOT RECOMMENDED TO INCLINE THE
TRACK DISCS TOO MUCH, THUS PREVENTING
SERIOUS DAMAGE TO THE MACHINE.
6.11 INCLINATION OF THE FOLDING
PARTS
At the connection point between the folding parts and the
central chassis, there are adjustable stops which allow the
folding parts’ inclination angle to change.
Fig. 58 A
1-
Loosen the two securing nuts (A, Fig. 58).
2-
Remove the screws and nuts.
3-
Adjust the folding stops.
4-
Insert the screws and nuts in the new housing (3, Fig. 35).
DURING NORMAL SOWING CONDITIONS, THE
FOLDING PARTS SHOULD BE SLIGHLTY LOWER
THAN USUAL TO ADAPT TO TERRAIN IRREGU-
LARITIES. FOR A BETTER ADAPTATION TO THE
TERRAIN, SET THE HYDRAULIC CIRCUIT OF THE
SOWING EQUIPMENT IN NEUTRAL POSITION.
IN VERY TILLED OR LOOSE LAND, AS WELL AS
IN SOILS WITH HIGH HUMIDITY, THE FOLDING
PARTS SHOULD BE LEVELLED TO STAY HORI-
ZONTAL.
