Planning the plantation - Correct seed rate
Set-up instructions
Consider that the amount of plants in the harvest is always smaller than the number
of seeds distributed in the planting operation, due to the following factors: germination
rate, physical purity, vigor (provided in the seed pack), plagues and diseases that may take
place during the cultivation cycle.
Also, consider that during the plantation slippage or skidding of the planter tires can
occur, according to the local working conditions.
How to calculate the slippage index of the planter:
• This index is obtained by comparing the number of spins the tire will perform, being
the planter with empty hoppers and then filling them up, moving the planter around to see
the difference;
• Being the planter empty and normally hitched to the tractor, set a starting point on
the ground and on the tire. Move the planter until the tire complete 10 (ten) spins. Measure
and write down the traveled distance.
Calculation:
Distance with load – Distance without load x 100
Distance without load
The tires must have the same design, same inflation and same adjustment of
springs over the wheelset arms.
NOTE
Retighten all sets, paying attention to the following points:
• Retighten the nuts that fasten the seed row units on the frame
gradually, avoiding to totally tighten each nut at a time;
• That information is also useful between a row unit and another. So,
do not totally tighten a row unit at once, but gradually;
• When switching between this nut tightening operation of a row unit
and passing to another, it is necessary to spin the hexagonal shaft
to keep the proper alignment and avoid locking.
IMPORTANT
Fill up the planter hopper, repeat the previous procedure and write down the traveled
distance.
