7.
Carefully remove the soil covering four of the
planted seeds.
8. Measure the distance from the surface of
the soil to the bottom of each seed. Use one
of the following two methods.
Using a ruler and a straight edge: Place
°
the straight edge flat against the surface
of the ground. Hold a ruler vertically in the
seed furrow next to the seed. Measure the
distance from the bottom of the seed to
the bottom of the straight edge.
° Using the seed finding tool:Place the
long flat section (1) of the seed finding
tool against the ground with the short flat
section (2) inside the seed furrow (3).
Press the short flat section in the ground
until the long flat section is flush with the ground. Measure the depth of the furrow using the
marks on the short flat section.
Result
The measurement taken is the actual seed depth.
9.
Check the depth of the seeds in two of the other furrows behind the machine.
10. Compare the measurements to the correct seed depth and adjust the machine as necessary.
After finishing the procedure
Continue to check the seed depth until the machine plants the seed at the correct seed depth.
