Kubota has unveiled a striking vision for farm work: a hydrogen fuel-cell tractor that can drive itself or be steered from a distance. Revealed at Expo 2025 Osaka Kansai, the concept spotlights two trends reshaping agriculture — cleaner fuels and automation — and asks whether farms can adopt both at scale.

Kubota’s hydrogen tractor: a first look at the concept shown in Osaka

At the world fair, Kubota presented a functional concept rather than a production machine. The prototype replaces a diesel engine with a hydrogen fuel cell system. Designers say the tractor emits only water while running.

The company emphasized dual control modes. Operators can let the tractor run autonomously across fields or take control remotely when tasks demand human judgment. Kubota framed the vehicle as a response to labor shortages and the push to cut farm emissions.

Why hydrogen might suit heavy agricultural equipment

Battery electric power has won the race for most passenger cars. But heavy machinery presents different constraints.

• Battery packs add significant weight and bulk.
• Recharging large batteries takes long downtime on tight schedules.
• Hydrogen refueling is much faster than charging and can sustain long operating hours.

Kubota argues that for long, continuous field work, hydrogen offers a practical balance: steady power output and quick refueling. That makes fuel cells attractive for tractors, loaders, and other heavy units where uptime matters.

Key features and how the system works

The concept integrates a fuel cell stack, hydrogen storage, and electric drive motors. That lets the tractor produce electricity on board and drive like an EV.

Performance and operation

• Continuous high-power delivery for extended tasks.
• Rapid refueling compared with plug-in charging.
• Dual-mode operation: autonomous navigation and remote human control.

By combining electric drivetrains with hydrogen fuel cells, the design keeps many benefits of EVs while sidestepping lengthy charge cycles. Kubota highlights that the machine can operate for long shifts with only water as exhaust.

Autonomy on the farm: reducing labor gaps

Japan faces an aging farming population and fewer workers entering agriculture. Kubota positions the tractor as part of a solution.

• Autonomous routines can handle repetitive field work.
• Remote operation allows one technician to manage several machines.
• Automation can free farmers for value-added tasks.

Still, engineers will need to prove the system in diverse field conditions. Kubota plans demonstration trials to validate navigation, obstacle avoidance, and remote-control safety.

Refueling infrastructure and hurdles to practical use

Technology alone does not make a market. Fuel access and costs remain central obstacles.

• Japan already has more than 150 hydrogen refueling stations, mostly in urban areas.
• Rural coverage is sparse, making field refueling difficult today.
• Building a countryside supply chain is essential for commercial adoption.

Farmers will need practical options for topping up hydrogen on remote plots. That might mean mobile refueling, on-site electrolyzers, or public investments to expand networks.

Where Kubota goes from concept to reality

Kubota presents the tractor as an experimental platform. The company intends to refine the design based on farmer feedback and to run field demonstrations. It has not committed to a sales timeline.

Industrywide, many manufacturers still rely on diesel for now. Kubota’s roadmap depends on proving autonomy, securing hydrogen access, and meeting cost targets. If those elements align, hydrogen tractors could join a growing list of heavy-equipment applications exploring alternatives to fossil fuels.
