AS-Motor’s Commitment to the Environment

Ecological Mowing – Protecting Biodiversity & Natural Habitats

AS-Motor’s high grass mowers are designed to work in harmony with nature, offering selective mowing solutions that promote biodiversity while effectively managing dense vegetation. Unlike conventional mowing methods that strip landscapes bare, AS-Motor mowers support wildflower regeneration, protect pollinators, and maintain essential wildlife habitats.

By allowing for partial and seasonal mowing, these professional-grade machines contribute to healthy ecosystems and sustainable land management. Whether used in nature reserves, ecological landscaping, or protected areas, AS-Motor mowers ensure precise vegetation control without disrupting fragile environments.

Additionally, AS-Motor’s mulching technology naturally returns organic matter to the soil, enhancing soil fertility, reducing dependence on synthetic fertilizers, and improving plant resilience. Thanks to low-impact tires and lightweight designs, soil compaction is minimized, ensuring long-term soil health and improved water absorption.

Sustainable Mowing – Innovation for a Greener Future

AS-Motor is setting new standards in sustainable mowing technology, integrating durability, efficiency, and environmental responsibility into every mower. Over 90% of AS-Motor components are made from recyclable steel and metal, ensuring exceptional longevity while minimizing environmental impact.

Designed for fuel efficiency and reduced emissions, AS-Motor mowers feature lightweight yet rugged construction that lowers fuel consumption and CO₂ emissions without compromising performance.

The future of professional mowing is electric, and AS-Motor is leading the way with battery-powered innovations. The AS 920 E-Sherpa 2WD, powered by FusionCore battery technology, delivers the same rugged performance as combustion models while operating quietly and emission-free. Engineered for steep slopes, high grass, and sensitive environments, this zero-emission ride-on mower is the perfect solution for municipalities, nature reserves, and eco-conscious professionals.
