AI adoption challenges for farmers

Highlights

Agco’s Outrun autonomy platform enables driverless tractors for U.S. farms, with retrofit costs at $60,000 plus a $9,000 annual fee, addressing ongoing labor shortages.
Purdue University research shows Midwest corn and soyabean farms require labor wages above $140 an hour before autonomous equipment yields better returns than conventional machinery.
Illinois Soybean Association leaders and farmers report variable reliability for AI applications like geo-data maps, with inconsistent results and external costs offsetting potential efficiency gains.

Autonomy costs and adoption hurdles

As reported by Financial Times, AI-driven equipment is expanding across U.S. agriculture, from disease-detection glasses and precision weed control to autonomous grain carts that work alongside harvesters. On Bob Stewart’s 10,000-acre Illinois farm, a driverless tractor using Agco’s Outrun autonomy platform pulls a grain cart beside a harvester, then heads on its own to unload before returning to the field.

Agco says retrofitting an existing tractor with the autonomy kit costs $60,000, plus a $9,000 annual fee. Stewart, whose family has farmed in the area since the 1850s, says labour is his biggest concern because six full-time staff, including family members, must manage large acreage and extensive equipment.

He says the U.S. farm labour shortage is longstanding, with fewer children returning to farming after college over the past two decades, while immigration crackdowns have added pressure. Agco chief executive Eric Hansotia says demand for autonomy differs sharply by farm type, noting that labour-intensive sugarcane operations may want the technology immediately, while some Midwestern growers with 2,000 acres may be less motivated to hand over driving tasks.

Returns depend on farm economics and priorities

Chad Fiechter of Purdue University’s Centre for Commercial Agriculture, who co-authored a study on autonomy for Midwest corn and soyabean farmers, says the economics remain difficult under current assumptions. The study found labour wages would need to rise above $140 an hour before autonomous machinery generates higher returns than conventional equipment.

Fiechter says some grain farmers may still adopt the technology for lifestyle reasons rather than profit, because time away from the cab can matter as much as financial payback. He adds that while he values new technology and used it in his own decade of corn and soyabean farming, it can also become a distraction that solves smaller problems without addressing the main constraints on a business.

Brady Holst, vice-chair of the Illinois Soybean Association, says a driverless grain cart is appealing because it could free one worker for other harvest tasks. But he says some AI applications, including AI-generated geo-data prescription maps, are not yet reliable enough because repeated runs can produce different results, while weather, tariffs and diesel costs can wipe out any marginal gains.

Stewart says U.S. agriculture has room for both adopters and holdouts. In his view, choosing not to invest in the newest AI systems does not mean a farm will not still be operating a decade from now.

Our earlier article on a KPMG U.S. CEO survey found that AI agents are delivering mostly incremental efficiency and growth gains so far, with only a small share of executives calling them transformational today. It also highlighted that leaders expect continued investment in AI infrastructure alongside hiring and retraining, as organizations work through data, process, and skills changes needed to scale AI use.
