Big Battery Making a “Big” Difference with AGZA


CHATSWORTH, CA – Big Battery – a global leader in lithium battery repurposing, recycling, and manufacturing and the American Green Zone® Alliance (AGZA) – who helps transition the landscape maintenance industry from gas powered to cleaner lower impact technologies, for municipalities, universities, school districts, and golf courses have been collaborating on a little-known project to address the proliferation of Battery Powered Equipment in the landscape maintenance industry.   People are asking what are we going to do with all of the lithium batteries once finished with their useful life?  Luckily Dan Mabe, President of the American Green Zone Alliance, was introduced to Eric Lungren, CEO of Big Battery.   It started with a chance meeting between South Coast Air Quality Management District (SCAQMD) Board Member, and mayor of the City of South Pasadena Michael Cacciotti, who met Mr. Lungren while conducting interviews for the same journalist.  Following the interview, Board Member Cacciotti connected Big Battery with AGZA.

AGZA toured the Big Battery Headquarters in Chatsworth California and soon learned special things were happening there.  Big Battery was giving lithium

batteries a second life and also facilitating the recycling of lithium batteries.  AGZA understood the value of Big Battery right away as lithium powered equipment is currently gaining rapid popularity and workforce acceptance in the professional arena.   The two companies became acquainted and found a way to work together.

AGZA and the Arroyo Seco Golf Course located in the City of South Pasadena, which is an AGZA Certified Green Zone® had a problem to solve with a large greens mower operating at the course every day.  The mower was powered by a lead acid battery system and just after six short months lost substantial runtimes and placed the Green Zone rating at risk by possibly having to go back to using a traditional gas mower.   Big Battery said they could help by replacing the greens mower with a lithium system. Not only could Big Battery replace the batteries, they did it with used / repurposed Tesla Model 3 cells.

AGZA transported the greens mower to the Big Battery R&D center, and they went to work right away.  Their lead engineer Walson and AGZA went over the operating parameters of the mowers existing controllers and voltage ranges.  From there, he and his team modified the battery carriage and customized a battery bank which allows the mower to cut eighteen greens plus a practice putting green.  After this conversion, the Big Battery repurposed lithium battery system has powered the mower for over a year and a half with no issues to date.  The result is lower emissions, noise, and operating costs.  The ability of this mower to operate everyday at the course also keeps their AGZA Green Zone firmly intact and at a high rating.

With this pilot project Big Battery and AGZA were able to utilize repurposed lithium cells.  The result is substantially reduced toxic emissions – ozone-forming chemicals, fine particulates, and carbon monoxide – as well as reduce greenhouse gases, noise, fuel spillage, fuel consumption, and solid and toxic waste.  It’s a triple win for the people, planet, and profits!

CHANGING BUSINESS AS USUAL through AGZA Green Zone® Certification


(Los Angeles, CA — November 2021) By Esther Wu

The American Green Zone Alliance (AGZA), AOS (Automated Outdoor Solutions), and the Langton Group have formed a collaboration to benefit people, planet, and profits. AGZA Founder Dan Mabe and AOS President Joe Langton first met in early 2019. Both quickly understood that their companies had much in common and that by working together they could develop a business model for land care that would improve working conditions for grounds maintenance workers, enhance quality of life for communities, improve the environment, and increase profits for businesses.

So far, the group has created five robotic AGZA Certified Green Zones in Woodstock (Sweetwater, Woodstock Sterile Solutions, Dura Bar), Geneva (Marklund), and Marengo, Illinois (Thompson Linear). An AGZA Certified Green Zone is a defined area of land on which routine maintenance is performed with the use of quiet, low impact equipment. Green Zones are created through a structured, multi-step program designed to achieve an enduring transition away from fossil fuel-based landscape maintenance using battery electric, robotic, and people-powered tools. It has become the independently verified standard for low impact and sustainable grounds maintenance operations.

Education and certification are at the core of the program. The AGZA Service Pro Certification Course – a 15 lesson online course available in Spanish and English – is available to educate the industry and help them develop professional competence in the new technologies. Joe Langton and dozens of his employees at AOS and the Langton Group were among the first to become AGZA Service Pro® Certified. “The feedback was positive with employees appreciating the quality of the course and its comprehensive coverage” said Joe Langton. 

Training in the use of battery electric equipment and proper set-up and installation of robotics and power hubs in the Green Zones are also critical. Following professional certification of the work crews, the AGZA, AOS and the Langton Group began work that resulted in the first successful robotic mower AGZA Certified Green Zone in the nation. “Previously, AGZA had attempted to create robotic mower Green Zones without success. Having Joe Langton’s technological expertise and experience were key to the success of the project,” said Dan Mabe.

IllinoisUnderstanding the environmental and economic benefits resulting from Green Zones are another essential component of the program. Non-profit organization, Quiet Communities Inc (QCi) and AGZA team up to provide Environmental Landscape Footprint (ELF®) reports that quantify the beneficial reductions in carbon emissions, toxic pollutants, noise fuel spillage, and toxic waste, along with economic return on investment and cost-effectiveness.  “These metrics help organizations and individuals understand and communicate the tremendous difference a transition makes in improving the health of workers, the public, and the environment, as well as the substantial savings that can accrue over time,” says Jamie Banks, President of QCi. Organizations and companies can publish their ELF metrics on their websites and in their sustainability reports to communicate the progress they are making.

Dura Bar, located in Woodstock IL, was the first ISO9001:2015 certified company to receive the Green Zone designation for its twenty serviceable acres of green space maintained with robotic mowers. According to Dura Bar representative, Melissa Bollig, “the AGZA Green Zone Certification is aligned with Dura Bar’s sustainability goals and relationship with our community.” Thompson Linear implemented its Green Zone with Husqvarna Automowers® and battery-powered handheld equipment that quieted land care operations on their property as well as in the surrounding community.

The future looks bright for AGZA, AOS, and the Langton Group. They have already lined up dozens of multi-acre projects with municipalities, private companies and academic institutions who increasingly are coming to appreciate the value that independently verified low impact land care operations can bring to their sustainability projects.

Oregon No Longer Manufacturing 120V Tools

Oregon 120V Commercial Tools No Longer Manufactured

Sadly, it is the end of a great line of commercial battery electric tools

AGZA founder Dan Mabe has some special words for the dedicated team at Oregon

AGZA regretfully informs our AFTC audience and network of commercial operators of the following industry update: As of February 2021, Oregon will no longer manufacture the 120V Professional Series line of battery-operated lawn and garden equipment. This is disappointing news for AGZA and the industry, as the Oregon product line has received nothing but positive feedback from our Green Zone project managers and other users of the 120V tools.

AGZA commends Oregon for designing, testing, and bringing their powerful robust suite of battery electric tools to market.  We acknowledge the critical contribution Oregon made showing us all what can be achieved with battery electric technology.  Their efforts will help the technology evolve for years to come.

Oregon 120V tools will still be AFTC Certified as we have received notice that Blount is committed to honoring all warranties on equipment purchased prior to the discontinuation date. Further, Oregon will have aftermarket service and parts available for existing users of the equipment.

How Solar Integration is becoming more popular

It appears the use of solar energy is becoming more commonplace in today’s society and a new batch of entrepreneurs are finding new and innovative ways of implementing solar power.  This outside of the box thinking can save businesses money and benefit the environment as well. The following businesses have flexed their creative muscle and found new ways of turning the sun into profits.

A few years ago these alternative solutions were not easy to come across but with more companies developing battery electric equipment to be charged, many may be encouraged to transition away from conventional internal combustion technologies. As solar panels begin to drop in price it only makes more sense to use this low cost renewable source of electricity. Now smaller businesses can harness the power of the sun and make a real difference on the environment.

Ben and Erin Kaden have found a way to turn their mobile detailing business into a green solution. The founders of Narwhal Solutions first implemented solar panels to power their washers and vacuums. It was a decade long journey but they have found a way to help other businesses make the conversion to clean energy sources. Inspired by the events of the Deepwater Horizon disaster, they started their detailing business in 2010 and ran their vehicles and generators with fryer oil. After finding a way to make solar power mobile they took further strides in cleaning up the way people do business and recreation.

“Solar power generation for mobile application could potentially simplify power needs while saving money. On top of the cash saved by no longer needing to buy gasoline to power your daily tools and equipment, you’re moving into the future,” says Ben Kaden

Narwhal Solutions offer solar powered generators that fit into the bed of a pick-up truck. For those that need a bit more power they offer towable’s in a range of sizes. These generators can accommodate any needs from wireless tools to heavy duty power tools. For more information go to 

Another pioneer in the new wave of unique solar powered businesses is Solar Earth Lawn care owned by Gus Mariscal. With solar panels mounted to the roof of their truck Solar Earth Lawn Care has found a clean source of energy to power everything from lawn mowers to leaf blowers and hedge trimmers. In the competitive field of landscaping it is important to find a way to stand out says Gus.

Maintaining a pristine green lawn can be far from actually being green. On top of the cost of gasoline, the negative health impacts to his crews were too much for Gus.  Additionally, Gus was concerned about air and noise pollution created by his gas business when he decided to convert to a sustainable solution. Solar Earth’s use of electric equipment and people powered tools comes with the added benefit of having no fumes and low noise. Recently they have brought in help from robotic electric mowers made by Husqvarna that cut your lawn in silence while you go about your day. Solar Earth Lawncare is the first solar powered landscaping company in Indiana and an AGZA Certified Service Pro business. Gus hopes more companies follow this trend.

Linus of RLCS showing the simplicity and safety features of the Husqvarna Automower blades.

It takes seven days for a sitting mower to maintain 500 acres of lawn across 14 campuses of the Eastside Union School District. The department’s checkbook records a hefty investment of $100,000 for the large traditional gas mower, continuous maintenance fees, and the costs of 30-40 gallons of gasoline per day. This current system is nothing but an unfortunate concoction of time and cost inefficiency mixed with a large dosage of unsustainability.

Luckily, Robotic Lawn Care Systems (RLCS) presents the modern and viable alternative with its robotic fleet for lawn care services. AGZA introduced RLCS to Roger Silveira on its mission to make Evergreen Valley High School the second AGZA green zone high school in the nation. RLCS offers the Husqvarna Automowers with the Fleet Service App, giving the crew full control over their scheduled operation and location. Since the boundary wire was not set up yet and the robot hadn’t had time to analyze the area and it’s ideal mowing path through an adjustment period, the Husqvarna Automower was just set to a demo mode to exhibit its capabilities. It put on an impressive display run on the hilly mound with barely any audible operation noise. Everyone present was genuinely impressed by its outstanding performance. The automated system eliminates the two most pressing and evident concerns over gas lawn tools: Emissions and Noise. In addition to only using 2% of the energy of a ride-on option, the Husqvarna Automowers do not release any pollutants. They stay between 55-58 dB, practically heaven to the ears of the crew, and school students, who have been in the presence of the 95-100 dB riding mower. As the demo carried on, the Automower ran into the foot of a tree. Instead of trying to forge ahead, it smoothly spun to the left and continued on its way. The robots are as safe as traditional mowers. The robots can pivot from obstacles and stop immediately when lifted, presenting no harm to its surroundings.

A major benefit of the automated system is the resulting increased productivity of the crew. While the Automowers take care of the straightforward and repetitive job of mowing the fields, the crew gains the ability to focus on more detailed orientated tasks that need to be done neatly and with precision. Such duties are not as pressing as mowing so they may normally be put off and neglected due to the crew’s limited time. With the crew’s workload lightened by the weatherproof robots operable day and night, rain or shine, the workers can focus on enhancing the property on the next level.

Audrey Wen is a junior attending Dougherty Valley High School in California. She is passionate about bringing light to the harms of gas powered lawn equipment and is eager to bring about their phase-out. Audrey created to combat the predicted growth of smog-forming emissions due to small off-road engines, specifically lawn maintenance gear. During her free time, she enjoys crafting and playing the Chinese violin.

(South Pasadena, CA — August 15, 2020) by Esther Wu

EGO Leaf Blower on Golf CourseIt’s 4:45 Sunday morning at Arroyo Seco Golf Course in South Pasadena.  It is almost pitch black and the chorus of birds singing can be heard in the background.  There are residential homes adjacent to the course who can practically call the golf course their back yard.

On this day, the American Green Zone Alliance (AGZA)  meets with the grounds crews for a “shadow” outing to verify that the crews are honoring the AGZA Green Zone Certification the golf course pledged to uphold by using only electric hand held tools for routine everyday maintenance.  These tools are blowers, weed-whips, hedge trimmers, edgers, and chainsaws.  Under the certification the course is also using a 52″ Mean Green electric mower and an electric greens mowers which was recently converted to a lithium platform.

AGZA is also there to continually track and verify the performance, durability, and workload capability of the various electric equipment used to maintain AGZA Certified Green Zones.  Any tool that shoulders the responsibility of Green Zone certifications has to be exceptional.  Today’s outing was focusing on the blower use.  Every morning seven days a week, three hundred and sixty five days a year, the dedicated crews wake up at before the crack of dawn to prep the course for the first tee times which start at 7:00 AM.  Part of this everyday ritual is blowing off all eighteen greens to prep them for the greens mower.  AGZA shadows grounds crew member Mike in the darkness to his first area around the club house and practice putting green.  After that he heads for hole number one and maintains a rigorous and steady pace to stay ahead of the greens mower which is using head lights for the first few greens waiting for the sun to finally show itself.

Mike is using an EGO, 580 CFM handheld blower.  He started with a couple of other brands but settled into this particular model from EGO.  He likes the sound profile, power, and ergonomics.  The crews stressed that they have to be picky and discerning on even which “electric” leaf-blower models they use that early in the morning.  Dan Mabe President of AGZA states “not all electric blowers translate to noise relief”.  The reason for this he explained is that different brands may have similar dB ratings but the harmonics and the pitch can be harsh on the ears with some models out there.  EGO scores very high among only a handful of other AGZA AFTC© Certified electric blowers on the market.

Mike uses up to three EGO 7.5 amp hour lithium batteries to completed is morning workload.  He informed us that he usually discharges two full batteries and half of the third one.  These particular batteries are seventeen months old and are used every single day.  AGZA tracks the fuel savings with the crews achieved by using battery power instead of gas and two-stroke mix previously used to power their gas leaf blowers.  The reduced maintenance of their electric blowers compared to their old gas ones is always enthusiastically mentioned by the course crews.  Other EGO equipment used at the course is the commercial LBX6000 blower, and HTX6500 Hedge trimmer.

American Green Zone Alliance Certification for a Second Eastside Union School District High School, Evergreen High

I thought I understood the difficulties going in. I did not.

As I stepped into one of the portables of East Side Union High School District (ESUHSD) after meeting Dan Mabe, the Founder and CEO of AGZA, and Roger Silveira, the Director of Facilities, Maintenance & Operations at ESUHSD, I thought nothing more about the training workshop I was attending than an informational session for me to further my understanding of the health risks of gas equipment.

Dan Mabe presents STIHL’S 36V, AP battery electric line up.

Mr. Mabe started off the presentation with his personal attachment to this initiative. I learned that he has dedicated himself to changing the lawn equipment industry to become more clean, efficient, and sustainable since 2006. AGZA has developed a true behavior modification certification that is tried and true. The current movement towards alternatives to gas is largely facilitated by AGZA and Mr. Mabe’s dedication. In conjunction to his story, Mr. Mabe delved into the detrimental exhaust emitted from gas equipment through sobering statistics and video clips. Some of his audience was engaged, while others appeared to rather be attending a driver’s ed class.

Dan gave numerous examples of other AGZA Certified Green Zones, some covering over 120 acres of “serviceable” property. These certifications require the phasing out of all two-stroke equipment for “routine” maintenance but can score higher the more gas operations are phased out during the process.

Dan coordinated with Roger to have most of their new battery electric gear staged inside the classroom.

As the workers pitched in on issues of the battery powered equipment through their experiences, Mr. Mabe under Mr. Silveira’s watchful eye calmly explained necessary cleaning and usage measures to ensure optimal usage efficiency and lifespan potential of batteries and tools.

With the first ESUSD AGZA Green Zone (Yerba Buena High School), there were a few issues with acclimating to the new technology. The challenge with the switch in equipment came from the workers’ treatment of the new tools as their old gas ones and their expectations for them to work the same. One aspect of AGZA certification is a support program to assist all grounds maintenance workers in their transition to more environmentally friendly and energy efficient lawn equipment. One gentleman who had been part of the crew who first used the electric gear stated that he did not want the certification to be a blame program but rather a support program; Mr. Mabe explained there will need to be some modifications in the overall approach when phasing out internal combustion operations. Nonetheless, I understood where the man was coming from. Despite their initial efforts to adopt the new equipment, the results were mixed but overall the electric equipment had been handling the campus workload for over a year now.

STHIL’S AP line has been used in AGZA Certified Green Zones for nearly a decade.

I understood that asking an entire industry of gas users to make the switch to a completely foreign technology to meet their same end was challenging, especially so because the workers did not want to be told what to do but rather shown a credible, different way to do it. Being further told how to do their work by people seemingly oblivious to their concerns further distances the gas maintenance industry from the movement that expects rapid change. The impacts on distributors, dealers, and the grounds maintenance industry who are heavily dependent on fossil fuels to power their industry are recognized, but they can be managed with the education and professional guidance offered by AGZA to help navigate the changes being asked of them.

As Mr. Mabe touched on the noise reduction that battery powered equipment would bring to the crew, I overheard two men near me discussing their opinions on the noise. Both acknowledged going about their daily rounds without any form of ear protection. I couldn’t help but react in concerned shock. That was exposures of up to 100 dB of noise at the ear for hours a day, hundreds of days a year, and who knows how many years.

Through that little snippet, I realized that the workers were already accustomed to what they had. Getting used to new equipment will definitely be a challenge for some and easier for others who are more receptive.

Nearing the end of the workshop, everyone stepped out of the room to take a look at the mower. As Mr. Mabe shared improvements of the new mower that would be arriving soon, the men were clearly divided into two groups. The first consisted of those who were actively crowding around the mower and displaying genuine excitement at the improvements that would be coming their way. The second stood in the shade to evade the sun with unconvinced and unsure attitudes. Just as I noticed this divide, a member of the first group walked over to someone from the second group. He analogized the gas equipment to an ex-girlfriend and the battery powered equipment to a new girlfriend. While the ex may have been the right match at that time, you are no longer together for a reason. The new girlfriend will never be the same as the old one, so you need to adapt to a different partner. In current times, we must consider how to preserve the environment and eliminate excessive gas emissions. Within this year, smog-forming emissions from small off-road engines will exceed those of passenger cars, and those numbers are only predicted to steadily rise according to the California Air Resources Board. It is time to acknowledge this prevalent issue that has flown under the radar for too long.

Pictured here are more STHIL 36V AP tools and a Mean Green, 60” ZTR mower. Mean Green Mowers have been used in large scale AGZA Certified Green Zone projects for over seven years.

The workshop concluded quite successfully considering its rocky start. As it had progressed, more and more workers gained faith in this transition. This is truly attributable to AGZA’s persistent efforts and its collaboration with the ESUHSD. Without Mr. Silveira’s willingness to embrace change in the district, the project would not have progressed to its current stage. This ambitious journey must acquire full-on participation from governmental agencies, non-profits, and the private sector in order to reach a stage where we no longer have to worry about the issues of gas powered lawn equipment to our public wellbeing and environment. Governmental agencies address gas equipment usage to a certain degree, but do not share the sense of urgency that AGZA stands by. AGZA will continue to facilitate the prudent and responsible implementation of battery electric, and people powered operations over gas, but it may take a combination of regulations from those at the top and grassroots efforts to make significant changes. The hope is that the current gas powered industry will reasonably embrace and implement cleaner technologies at a pace that will help governmental agencies reach their clean air attainment goals on time.

On the car ride back home, I contemplated Mr. Mabe’s words in addition to what I had seen firsthand at the workshop. Even now, I don’t dare say I understand all the difficulties of this project. All I know is that everyone must come together to combat this issue – this is no small matter. I hope that change and acceptance is imminent.
