Zero-emission tractors perform many tasks of diesel tractors, without noise or exhaust
The University of California, a national leader in sustainability, has pledged to become carbon neutral by 2025. To reduce its reliance on fossil fuels, UC Agriculture and Natural Resources has replaced several of its diesel-powered tractors with electric tractors at its research and extension centers.
Seven of the nine UC research and extension centers – Intermountain located in Siskiyou County, Hopland in Mendocino County, Kearney and West Side in Fresno County, Lindcove in Tulare County, Desert in Imperial County and Hansen in Ventura County – started using the Solectrac e25 in July. The researchers plan to share what they learn from using the electric tractors.
“Charging is easy, we are using a standard 110V connection, no charging station needed,” said John Bailey, director of the University of California Hopland Research and Extension Center. “For faster charging, you can use a 220V connection – again, no charging station needed, just a regular receptacle – but we haven't gone there yet.”
The electric tractor runs for about five hours, depending on the type of use and the speed, on a charge.
“We will use the electric tractor to mix the soil for planting trees in the greenhouse,” said Ashraf El-kereamy, director of UC Lindcove Research and Extension Center in Exeter, which focuses on citrus research. “Also, for pulling the trailer with the fruit bins during harvest, it will be good as it does not emit any gases.”
The electric tractor is being used to move materials in the loader at UC Hopland REC. “It has worked well for this, functioning similarly to a standard diesel tractor,” said Bailey.
“We have also used it to clean our sheep barn, scraping the pens to get ready for lambing season,” Bailey said. “This involves pushing or dragging straw bedding and manure. The tractor functions well in tight spaces due to its compact size.”
Bailey learned one downside is that the front end is a little too light, making it difficult to generate enough downward pressure with the loader to effectively scrape the floor without reducing the front wheel traction.
“We are planning to add some weight to the front, a standard practice with tractors to increase traction. The tractor has the mounting to enable this so it should not be a big deal,” Bailey said. “Our operators really appreciate the lack of noise and exhaust, especially when working in the barn or in tight spaces.”
The small electric tractor is also being used in tight places at the UC Intermountain Research and Extension Center in Tulelake.
“The tractor that we obtained from the company is too small for the majority of our farm needs,” said Rob Wilson, Intermountain REC director. “We purchased a small box scraper and rototiller for the tractor and we are using it around our facility grounds. We also use it out in the field in tight spaces that are too small for our larger tractors to operate.”
“The tractor is quiet, powerful for its size and operates very similar to the diesel-powered tractors with regard to the controls, hydraulics and three-point assembly. The tractor also has a lot of torque and speed.”
Annemiek Schilder, director of UC Hansen Agricultural REC, added, “I think another advantage is that the tractors can go very slowly, which is helpful for some uses such as harvesting.”
Kearney, or KARE, will be using its electric tractor to mow and rototill in smaller, narrow blocks and will use the front loader to move and apply mulch and soil mixtures.
“We will use it around buildings because it's quiet and doesn't emit any gas,” said Vincent Silva, Kearney's superintendent of agriculture. “The main issue I have with the electric tractor is with it being so quiet, it may not allow us to hear any problems."
The researchers will continue to evaluate the electric tractors throughout the year.
“Our main usage will come in the spring, mowing around our headquarters and on roadsides,” Bailey said. “We are purchasing a 4-foot flail mower that can mount to the rear PTO, but won't really put it into use until April.” The power take-off, or PTO, is the shaft that transfers power from the tractor to the attachment.
Other benefits of electric tractors include no engine oil to change and no diesel fuel.
“If the farmer already has solar, they will see close to zero fuel charges,” Bailey added. “Even without solar, their fuel costs should be reduced depending on local electrical cost. Also, the engine only has one moving part compared to dozens in a diesel tractor so maintenance costs should be reduced significantly, something that is proving true in electric cars.”
The Solectrac e25 tractors each cost $27,999 and the optional loader was about $4,000.
The California Air Resources Board is offering incentives to buy zero-emission equipment through its Funding Agricultural Replacement Measures for Emission Reductions Program. FARMER provides funding through local air districts for agricultural harvesting equipment, heavy-duty trucks, agricultural pump engines, tractors and other equipment used in agricultural operations.

Commitment of $690,000 supports UC South Coast Research and Extension Center, 4-H programs
During a “GROW Field Day” when 100 high school students enjoyed harvesting and tasting avocados, the Orange County Farm Bureau announced a $690,000 gift to expand University of California-affiliated programs that introduce young people to agricultural careers.
The students from four schools across Southern California participated in the GROW program on May 13 at the UC South Coast Research and Extension Center in Irvine, a UC Agriculture and Natural Resources facility that organizes and hosts these educational programs.
“Part of the mission of Orange County Farm Bureau is to support the development of the next generation of agriculturalists,” said Casey Anderson, executive director of OCFB, in announcing the five-year commitment that will begin in 2023. “Through our partnership with South Coast Research Extension Center and support of Orange County 4-H, we are thrilled to provide opportunities to young people to directly connect with food production and myriad research and career opportunities in agriculture.”
Hundreds of local youth are served every year by Orange County 4-H, a part of a nationwide youth development and education program, administered in California by UC ANR.
“OCFB contributions to our Forever 4-H Endowment will soon provide sustaining funds every year, indefinitely,” said Rita Jakel, Orange County 4-H program coordinator. “And their commitment to our Program Support Fund will help ensure that 4-H will continue to have the capacity to impact the youth of Orange County.”
GROW program introduces youth to agriculture careers
The GROW program, originally conceived by OCFB as a way to make agricultural experiences more accessible to more young people across the region, has engaged over 1,000 students from nine schools – many of them in urban areas where knowledge of agriculture is limited. The program builds on a strong history of collaboration between OCFB and South Coast REC, dating back to the early 2000s.
“UC ANR and South Coast Research and Extension Center are grateful for the trust the Orange County Farm Bureau continues to place in us to not only deliver agricultural education to the people of Orange County, but also to open the eyes of young people to fulfilling careers in agriculture,” said Darren Haver, director of UC South Coast REC.
“To me, it's like a great big outdoor classroom,” said Tammy Majcherek, a South Coast REC community educator specialist who coordinates the GROW program, along with colleague Jason Suppes. “There are so many possibilities of what we can connect to.”
Programs spotlight diversity of agriculture-related fields
Gina Cunningham, a teacher at Westminster High School (part of the Huntington Beach Unified School District), was excited to bring the 20 freshmen in her agricultural biology class to the GROW Day, where they get a glimpse of potential pathways in agriculture that “are not directly farming-related.”
“This gives kids an opportunity to see some things that are available to them that maybe they never have thought of – and there are a lot of things out there that I might not have thought of, either,” said Cunningham, who has degrees in animal science and agricultural education.
Thanks to OCFB's long-term commitment to the program, GROW coordinators Majcherek and Suppes said that in the coming years they would like to bring more students with career aspirations outside of traditional agricultural roles. In particular, they hope to reach out to young people with interests in culinary arts and food service, as well as in technology and engineering, which intersect with food production in the form of drones, robotics and artificial intelligence.
Regardless of their background, however, almost all of the students love harvesting crops from the South Coast REC farm, whether pumpkins, potatoes, or – during the most recent GROW Day – avocados. Majcherek said it's especially rewarding to hear the students talk enthusiastically about older siblings who went to a GROW program and came back with enduring memories – as well as some fresh produce.
“You know it's cool when they're taking selfies with their bounty,” she said.
Community members interested in joining the Orange County Farm Bureau in support of South Coast REC and 4-H programs are encouraged to make a donation on UC ANR's annual Giving Day, which runs from noon to noon on May 19-20.

UC ANR operates nine Research and Extension Centers (RECs), each location representing a unique climatic zone of the state. Extending from the Oregon border in the north, through the Sierra Foothills and Central Valley, along the Pacific Coast and south to the Mexico border, the REC System covers rich and unique resources connecting research and extension activities to regional challenges and issues. Now you can tour all of them without leaving your desk.
A virtual tour of UC ANR's nine research and extension centers is posted online at https://storymaps.arcgis.com/stories/3eac885337854895bd7039d7d4a131f1.
“The new REC tour was made to showcase a taste of the research and extension that goes on within the UC ANR REC System,” said Kathy Eftekhari, chief of staff to the vice president. “It was developed for general distribution to possible new partners across UC, CSUs, other research and Extension institutions across the country, private industry, state and local agencies, etc.
Employees are encouraged to view the tour and share it with interested stakeholders.
“Many people even within ANR are not fully aware of what goes on at each REC,” Eftekhari said.
