Row markers
Adjustments and operations
NOTE
The row marker utilization is very important to achieve an uniform spacing in the
plantation, thus facilitating the cultivation and harvest.
To adjust the marker discs it is just necessary to loosen up the bolts (A) and displace
the marker to the desired position. This distance can be obtained as follows:
• Drive some meters on a prepared soil, being the planter hitched.
• Measure the distance (D) between the center of the tractor trace and the center of
the first seed row (row in the planter extremity).
• Sum up the found measure with the spacing between rows (E) measure, considering
the spacing that is being used in the equipment.
• The result is the distance (F) that should exist between the row marker disc and the
center of the first seed row (row in the planter extremity).
Example:
D
- Tractor trace center to the center of the first seed row = 600 mm.
E
- Spacing between row crops = 900 mm.
F
- Distance to be found (?).
So:
D + E = F
600 +
900 =
1,500 mm.
F = 1,500 mm
This is the distance between the center of the first seed row and the marker disc
lowered to the soil.
For this practical adjustment it is necessary to keep the front and rear
gauges with the same measure, being the central measure of the front tires
equal to the rear ones.
