Fill up the planter hopper, repeat the previous procedure and write down the traveled
distance.
Calculation:
Filled distance – Empty distance x 100
Empty distance
The tires must have the same design, same inflation and same adjustment
of springs over the wheelset arms.
NOTE
Planning the plantation - Correct seed rate
Working preparation
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 it 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.
