15.2 SPREADING TEST
If the seeding device needs recalibration for a certain seed type or if it must be
checked for proper operation in accordance with the seed table (see section 5.0 Tab
1) a spreading test is to be carried out.
This is done as follows: (see fig. 10).
Fig. 10
1. Place the machine safely on the support legs on a level surface.
* Lock the machine to prevent it from moving.
2. First of all check the seeding slit opening for correct setting (see section
15.0).
3. Put the seed that is to be calibrated into the seed tray (4) and spread it
equally over the tray.
4. Remove the spreading tray 1.
5. Remove pins 2 on both sides of the machine.
6. Remove the funnel tray (3).
7. Slide the spreading tray underneath below the seed tray (4).
8. Turn the wheel (5) 13 full rotations counterclockwise.
9. Weigh the seed that is collected and multiply this by 5.37 (1275)
Weigh the seed that is collected and multiply this by 4.08 (1575)
Weigh the seed that is collected and multiply this by 3.06 (2075).
The result is the weight of the seed that is seeded per (kg) 100m

.
Compare the results with Tab. 1 (section 5.0) and do another spreading
test if necessary.
10. If the results of the spreading test do not reasonably match the calibration
values, check the seeding slit opening and adjust this if necessary (see
section 15.0).
11. Remount the parts in reverse order.
