Let’s use the following agricultural formula to calculate the fertilizer fl ow which
will be spread:
EXAMPLE:
Let’s take the following example to demonstrate the calculation: We need to spread
280 Kg of fertilizer per hectare, at a width of 10 m, and the tractor is moving at
a speed of 8 Km/hour.
Here is the informations:
Spreading rate = 280 Kg/ha.
Operating width = 10 m.
Tractor speed = 8 Km/hr.
THE FOLLOWING IS THE CALCULATION:
Flow = 280
Kg/h
X 10
m
X 8
km/hr
= 37 Kg/min.
600
So, we discovered, it is necessary to spread 37 Kg of fertilizer per minute to
achieve this. Now, only we need to defi ne what position it is necessary to place
the scale so that the valve is open enough to spread 37 Kg/min.
fl ow =
spreading rate (Kg/ha) x operating width (m) x tractor operating speed (Km/h)
600
This test is simple; just perform the following described procedure:
1. Load the machine with the product for spreading.
2. Remove
pendulum
A (fi gura 8).
3. Place a recipient for storing the product from the outlet (fi gura 8).
4. Move
lever
D and completely close the valve (fi gura 8).
5. Manually turn the adjuster C (fi gure 9) until the midpoint of the scale.
6. Turn on the machine (540 rpm in the power take-off).
7. Move
lever
D (fi gure 8), until the valve is completely open. Register the weight
of the product after 1 minute of fl ow into the recipient.
8. Redo the test, changing the scale position until achieving 37 Kg/min;
Increasing the scale to increase the fl ow and or decreasing it.
9. Once the adjustment is defi ned, reinsert the pendulum again.
CMT.: Register the required scale position, you may need the same setting for
future spreadings.
