Tractor with no driver plants field with no help

The only thing to do is set the speed of the tractor and the amount of seed to be planted, Zheng said.

"The device is particularly helpful to people in summer, as farm work seems more arduous than other times in hot weather," he said.

Zheng said now there are three automatic seeders in Huyi district for experiments. "More automatic devices will be introduced that will free people from heavy farm work," he said.
