China turns to driverless tractors, combines to overhaul agriculture

XINGHUA: A brand new combine harvester buzzes up and down a field in eastern China without a driver on board, chopping golden rice stalks and offering a glimpse of what authorities say is the automated future of the nation’s mammoth agricultural sector.

The bright green prototype was operating last autumn during a trial of driverless farm equipment as the government pushes firms to develop within 7 years fully-automated machinery capable of planting, fertilizing and harvesting each of China’s staple crops – rice, wheat and corn.

That shift to automation is key to the farming sector in the world’s No.2 economy as it grapples with an ageing rural workforce and a dearth of young people willing to endure the hardships many associate with toiling on the land.

Other countries like Australia and the United States are taking similar steps in the face of such demographic pressures, but the sheer scale of China’s farming industry means the stakes are particularly high in its drive to automate agriculture.

“Automated farming is the way ahead and demand for it here is huge,” said Cheng Yue, general manager of tractor maker Changzhou Dongfeng CVT Co Ltd, which provided an autonomous vehicle that was also used at the trial in the rice field in Xinghua, a county in the eastern province of Jiangsu.

However, the road to automation is long and littered with obstacles such as high costs, the nation’s varied terrain and the small size of many of its farms.

“I have heard of driverless tractors. But I don’t think they are practical, especially the really large ones,” said Li Guoyong, a wheat farmer in China’s northern Hebei province.

Most farms in his area are only a few hectares in size, he said by phone.

GOING LOCAL

To try to achieve its ambitious 7-year goal, Beijing is supporting trials of local technology across the country organised by industry group Telematics Industry Application Alliance (TIAA).

Members include state-owned tractor maker YTO Group, navigation systems producer Hwa Create and Zoomlion Heavy Industry Science & Technology Co Ltd 000157.SZ, which helped develop the combine harvester used in the Xinghua trial along with Jiangsu University.

The next trials are slated for the northeastern province of Heilongjiang and for the hills around the southwestern city of Chongqing in the first half of this year.

Those come after a string of automated developments in the sector.

YTO developed its first driverless tractor in 2017 and is aiming to start mass production soon, depending on market demand, said Lei Jun, an executive at the firm’s technology center, without giving a more detailed timeline.

Lovol Heavy Industry Co Ltd signed a deal with Baidu  in April to apply the tech giant’s Apollo automated driving system to its agricultural machinery.

“China is expected to climb the autonomous technology ladder very quickly, mainly because Chinese companies can access the local navigation satellite system, which gives them an advantage over their international peers,” said Alexious Lee, Head of China Industrial Research at Hong Kong brokerage CLSA.

He was referring to China’s ‘Beidou’ homegrown satellite navigation system, a rival to the U.S. Global Positioning System (GPS).

Beijing has included agricultural machinery in its ‘Made in China 2025’ campaign, meaning the vast majority of its farm equipment should be produced at home by that time.

Semi-automated technology is already fairly common on farms in places such as the United States, but fully-automated tractors and combines have yet to be mass-produced anywhere.
