**5. Discussion**

Through global analysis of the test process and results of the dandelion seed harvester, the deficiencies in the harvesting quality were investigated:

1. Environmental influences: Under strong external natural wind, the blowers fail to draw all falling seeds into the harvester, which may cause a collection loss. If the ground is rough, seeds falling off under the disturbance of the disturbing roller cannot be collected due to the rugged ground and long distance from the blowers that results in inadequate wind strength, thus inducing the collection loss.
