Adjustments and operations
To adjust the marker discs it is just necessary to loosen the nuts and displace the
extensor 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 (A) 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 (B) measure, considering
the spacing that is being used in the equipment.
• The result is the distance (C) that should exist between the row marker disc and the
center of the first seed row (row in the planter extremity).
Example:
A - Tractor trace center to the center of the first seed row = 800 mm.
B - Spacing between row crops = 500 mm.
C - Distance to be found (?).
So A + B = C
800 + 500 = 1,300 mm
C = 1,300 mm
This is the distance between the center of the first 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.
Follow the instructions that goes along with the illustration on the next page.
The row marker utilization is very important to achieve an uniform spacing in the
plantation, thus facilitating the cultivation and harvest.
