Green Commercial Lawn Mowers
Advances in electric batteries are driving our cars to a quiet, clean, energy-efficient future, and increasingly batteries are replacing fossil fuels and motorized equipment like lawnmowers. On top of that, innovative charging solutions are giving a second life to electric vehicle battery packs, and a whole new meaning to growing green.
There are 40 to 50 million acres of lawn grass in the U.S., making it technically the largest irrigated crop in the country. And an estimated 56 million lawn mowers are keeping all of those yards and golf courses trimmed.
If you consider that in one hour, a single gasoline-powered mower produces the same amount of emissions as driving 11 cars, and that an estimated 17 million gallons of gas are spilled each year while refueling lawn equipment, then maintaining our green spaces in the current manner isn’t doing any favors for the rest of the planet.
Which is why electric-powered lawn equipment is gaining favor with eco-conscious homeowners and forward-thinking commercial lawn care services.
The city of Burlington, Vermont has bought into the advantages of battery power, and is encouraging others to do the same.
DARREN SPRINGER: We at Burlington Electric are promoting electrification in many technology areas. We have electric vehicle programs, electric bike, electric bus, cold climate heat pumps for heating and cooling, and as part of that we also are promoting electric lawn mowers, both commercial scale, and residential. And we have rebate programs to support those, and we’re really doing it because our customers can save money, uh, when they mow electric compared to mowing with a gas mower. It's better for the environment for a variety of reasons, and it’s also quieter, so it’s better for our neighborhoods as well.
JOHN DAVIS: Consumer-grade electric mowers, blowers and trimmers are available in most big-box home improvement stores, and are cost-competitive with gas-powered models right off the shelf.
Larger commercial units, with their higher capacity batteries, may cost a bit more up front, but lower fuel and maintenance costs can pay that back and generate bottom-line savings in 3 or 4 years.
Burlington's incentive program offers up to $100 dollars for homeowners and $3500 for commercial operators who purchase electric lawn mowers. It has become their most popular rebate program, and other cities are starting to follow suit.
Blue Roof Foundation, a Dallas-based non-profit, educates consumers and pros on the tremendous potential of battery-powered lawn equipment, and came up with a unique battery recharging solution to aid in the transition.
Blue Roof has created this prototype trailer, equipped with lithium-ion modules re-purposed from a Nissan Leaf battery pack. It allows a typical lawn care crew to swap and recharge equipment batteries on location, and power through a full day of mowing without burning, or spilling, a drop of gas.
CARLOS OJEDA: The whole idea of the trailer is to really carry, store, and plug in one power cord that recharges everything inside. So the whole idea is that, during the work day, they can just come back, swap batteries, just like they were switching and refueling gasoline.
JOHN DAVIS: The high-energy battery packs that propel electric vehicles may lose capacity over time, yet still produce enough kilowatt-hours of power for less-demanding uses.
CARLOS OJEDA: Our main mission is really to reduce pollution by reducing the usage of small gas engines and switch that to electric. It just happens that, by repurposing the Leaf batteries, we’re actually at the same time, delaying the time that those batteries will end up in a landfill. So we’re giving them a second life as an effect of all this. So, it’s part of our mission, but the most important one is really to reduce pollution.
JOHN DAVIS: Reducing air and noise pollution while saving money is a win-win-win proposition. So, when it’s time to replace that old mower in your shed, remember that mowing clean can preserve the green all around us.
EV Tech Training
A shortage of qualified auto repair technicians has been an industry-wide problem for years now, but the high-tech nature of today’s advanced safety systems and high-voltage EV architectures are attracting a new generation of tech trainees to maintain the cars of tomorrow.
TODD RENFRO: “In the market today, automotive technician training is extremely important. For every seven technicians that are leaving our industry, we’re only having two come in to replace them. And unfortunately, the information we have at this time is, one of those two won’t make it past 12 months. So, we need to get young people excited about the automotive trade, all the opportunities that are in the automotive trade, and get them started in a path of career to be successful.”
As the number of electrified vehicles on the road increases, dealerships and independent shops alike are pushing to be ready for their service needs. But working around electrified vehicles means following very specific safety protocols for the high voltage systems and learning a whole new type of vehicle architecture. So, across the country, vocational schools big and small are adding electrified vehicle training into their curriculums.
Utah’s Weber State University has been teaching hybrid and electric systems to their students for nearly 20 years, and they also share their experience with technicians, educators and the general public in a unique five-day EV bootcamp, funded in part by the U.S. Department of Energy with the Utah Clean Cities and Communities Coalition.
JOHN KELLY: “I would say that for the last five or six years, probably half of the students coming through the class are teachers at other colleges and universities, high schools, technical programs that are interested in starting an EV or hybrid training program at their location, and are coming here to see how we do it. So that gives them a lot of ideas. They can go back, they may or may not have the same vehicles that we have, but it gives them an idea of what type of activities can they do at their school to, uh, enhance learning with their students.”
Like with conventional vehicles today, OEM-specific systems and procedures may have to be learned on the job, but weber’s program takes a universal approach, starting with the basics of high voltage wiring, and how battery electric vehicles work.
BRANDON STEVENSON: “Every OEM has their own common components, but they are named differently. So, unless you understand what that component actually does, it is a struggle. So, with our students that are already technicians, they’re coming in because they don’t know how all of the different OEMs work and they actually want to know it.”
And while new EV models continue to arrive on the market, remember that EVs and hybrids have been around for quite a while now, so there’s plenty of service experience to draw from.
BRANDON STEVENSON: “So, when you’re looking at where the industry is going and where it has come from, we’ve got a 2002 Toyota Prius in there now that’s 22 years old. That sounds like it’s really old and outdated, but it actually has a lot of technology that is still leveraged today. So, we’re able to show students where we were back in 2002 to where we are now in 2024.”
As the market share for plug-in vehicles grows, related jobs will open up as well over the next few decades, like electricians to install EV chargers, battery engineers and software developers, creating opportunities for existing workers to retrain, and appealing new career paths for the next generation to drive forward.
TODD RENFRO: “The excitement about EV, and also with hybrid, is that it’s the future. It’s what’s coming down the road. So, to be ahead of the curve and be prepared for that future, is exciting to a lot of the young students.”
