Row Markers Calculation
The total length of the row markers arm must be calculated by the
formula:
D = e (n + 1) - b Mark for the nearest tire of the seeded row.
D = e (n + 1) + b Mark for the furthest tire of the seeded row.

Onde:-
D = Distance of the marker disc to the center of the double disc of external
seeder unit
n =Number of rows;
b = Gauge of the tractor (in meters)
e = Spacing among rows.
EXAMPLE:
e = 0,70
n = 6 b = 1,42 m
D = 0,70 ( 6 + 1) - 1,42 = 1,74 m
