Dual Function for Complete Lawn Care

The S3840V combines two essential functions in one versatile machine. It includes a 22-spring tine scarifying cylinder for removing thatch, moss, and debris, as well as a 14-blade aerating cylinder for improving airflow and nutrient absorption. The scarifier rejuvenates the lawn’s surface, while the aerator penetrates deeper to enhance root growth and soil health. Both drums are easy to switch, providing ultimate flexibility and efficiency. This dual-action system ensures your lawn remains healthy, green, and well-aerated throughout the year.
