EAST LANSING, Mich. (AP) — In the soft dirt of an indoor horseback riding ring in August, a group of farmers got ready to test drive a new piece of equipment: an electric tractor.

As they took turns climbing in — some surprised by its quick acceleration — they gave real-time feedback to the Michigan State University researchers who have been developing it for over two years.

The farmers remarked on the motor’s quiet whir. Most were intrigued, or at least open to the idea. Some were concerned that the battery on the underside of the carriage would mean a lower clearance over the field, while others worried that it would simply be too expensive.

“What we hope to do when we retire is we want to get everything electric on the farm. The tractor is the last electric implement to get,” said Don Dunklee, one of the farmers to provide feedback. He runs a small organic vegetable farm that’s relied on wind and solar for decades.

The market is fairly new, but some researchers and entrepreneurs think electric tractors will be ideal for small farmers who care about sustainability and want to market their products that way. The small cherry-red, open-cab machine is well-suited for tasks like weeding fields of specialty crops like carrots or asparagus, or squeezing between the tight rows of orchard trees. Farmers with solar panels can avoid the cost of diesel.

“There’s reduced emissions, but before you get there, you have to be solving for other problems,” including noise, ease of use and cost, said Derek Muller, business manager for battery electric systems at John Deere.

There are downsides — electric tractors are aimed at filling a niche, not overturning the status quo. And while battery technology has come a long way, they can’t last all day or match the massive horsepower of a diesel engine that sets giant tractors cruising through the sprawling grain and soybean operations of the Midwest.

In addition to battery limitations, there are other structural obstacles. Most farmers do not have fast electric chargers, nor do they have solar panels to supply those chargers with free electricity — diesel would need to be much more expensive for the economics to turn sharply in favor of electric. But companies are starting to see an opportunity.

“For John Deere, it is not the only solution,” Muller said. “It’s not going to be where we lead our efforts. It’s going to be one of many options.”

The company has built a small utility electric tractor prototype. It joins a limited set of offerings from other companies like Monarch Tractor, which started in 2019 with the aim to help farmers, who have traditionally struggled with razor-thin profits, save money, work sustainably and more efficiently.

Ajit Srivastava, an agricultural engineer and Michigan State professor who hosted the farmer feedback session, wants to help smallholder farmers across the world. Such farmers grow about a third of the world’s food but many do it with only hand tools. 

“If we were to mechanize all the smallholder farmers in the world, there isn’t enough diesel out there to power them. So we have to find some other source,” Srivastava said.

It’s still a work in progress. Rain had postponed the feedback session, originally planned for the spring, because the tractor hadn’t been waterproofed yet. It also doesn’t have enough power for some jobs like tilling. But farmers generally like what Srivastava had developed. He hopes it could eventually be sold for roughly $30,000, substantially cheaper than some of the competition.

“The steering is really responsive. It just seems to run really smooth,” said Dunklee, adding, however, that it might not do everything he needs on a farm yet. “Probably the biggest thing would be it’s relatively quiet.”

One possible customer is the smaller farming operation of specialty crops or vegetables and farms for fun, not necessarily to make a living.

“They want to be self-sustaining,” said Patrick Woolcock, an associate engineering professor and agriculture expert at the University of Wisconsin-River Falls.

Plus, without diesel emissions, they can work in greenhouses and, with fewer parts, there’s hope repairs won’t be as complicated, at least once a readily available supply is established.

Still, some aren’t so sure electric has such a big advantage when it comes to automation. Tim Bucher, CEO of Agtonomy, a company focused on bringing autonomy software to farm vehicles, was all-in on electric a few years ago. But the technology has gotten so good that now his customers can pick and choose the energy source for their tractor and see similar results, he said. And with government electric vehicle subsidies disappearing, there’s less incentive for most farmers to go that route.

On his own farm, though, he opts for electric, and he says he’s seen economic returns.

And from an environmental perspective, “it also just makes me feel better,” he said.
