The automatic ball collection system contains a blower sub-system and a collection device. The blower sub-system drives the balls on the ground towards the collection device, and the balls are then automatically collected by the collection device. The blower sub-system contains a number of blowing devices configured at the corners capable of producing air flow substantially along ground surface so as to push the balls to roll towards the collection device. As such, the players' time and effort in constant bending and picking up balls, and the possible injury resulted as such are avoided.
