Los Angeles, California – The American Green Zone Alliance (AGZA) is pleased to announce that the STIHL RZA battery-powered zero-turn mower platform has earned AGZA AFTC Certification, joining just two other companies in this category. STIHL has made it its mission to design and manufacture a comprehensive battery-electric equipment platform that rivals similar gas-powered products. STIHL is successfully meeting the challenge of regulatory pressures and growing demand for quality battery-powered lawn and garden tools. This includes an evolving manufacturing base and supply chain shifting towards battery electric technology for our industry. AGZA has subjected multiple STIHL RZA mowers to some of the most grueling field-testing environments to ensure an independent assessment of this line’s performance, durability, and longevity. These real-world, day-in, and day-out settings represent the reality of our industry’s workload and aesthetic demands for their clientele.
AGZA STIHL RZA Testing – STIHL RZA mowers were placed in various regions nationwide, including:
- West Coast
- Midwest
- Southeast
Additionally, AGZA was able to visit and verify the robust use of STIHL RZA mowers in the Northeast, parts of Colorado, Texas, and Northern California. Testing in these regions allows for operation in different temperature extremes, moisture and humidity levels, dusty environments, and provided insights into contrasting attitudes towards battery electric technologies for outdoor power equipment (OPE).
The STIHL RZA Platform is AFTC Certified
The STIHL RZA platform joins an impressive growing list of battery electric riding mower platforms ready to meet the landscape maintenance industry’s demands.
AGZA focuses on safety, performance, durability, and longevity. We are confident that the STIHL RZA mower platform will help AGZA achieve its mission of transitioning into battery electric technologies and low-impact operations responsibly and profitably.
“AGZA cannot stress enough that our value and credibility depend on our voice remaining independent. We test and vet tools from manufacturers who recognize the value of our field certification, then provide this information to professional crews in commercial, municipal, and academic settings. We insist on the most candid feedback from operators — positive and negative. That’s our only guide in determining which brands and tools are viable for replacing gas machines in large-scale electric operations.”
AGZA AFTC & STIHL Backstory
The tool-testing relationship between AGZA and STIHL dates back to 2008, when STIHL became the first to launch legitimate commercial battery electric tools in the U.S. market with the STIHL AP professional battery platform.
Since then, AGZA and STIHL have cooperated to independently test the STIHL battery electric AK tool line for residential customers. Additionally, all new models brought to market are tested to ensure that high-quality standards are being maintained in the way AGZA, and the industry have come to expect from the STIHL brand.
