Vegetation management has always been a high-risk and challenging task on highway slopes, river embankments, abandoned mining areas, and wastelands overgrown with shrubs and weeds. These areas often have steep slopes (even exceeding 45 degrees), and the ground may conceal obstacles such as rocks and tree stumps. Traditional manual weeding is extremely dangerous, while ordinary lawnmowers are prone to damaging blades and engines. Addressing this industry pain point, remote-controlled lawnmowers equipped with a heavy-duty rotary blade system offer a revolutionary solution. Unlike traditional fixed flat blades, the rotary blade system uses a high-speed rotating drum to drive multiple sets of movable hammers or Y-shaped blades to strike and pulverize vegetation. This design allows the blades to automatically retract and avoid hard objects such as rocks, greatly reducing the failure rate. In the latest field tests, a tracked rotary blade remote-controlled lawnmower, when processing a steep slope wasteland overgrown with two-meter-high shrubs and weeds, was as efficient as 15 skilled workers combined, and could directly pulverize shrubs with a diameter of 3-5 centimeters and return them to the field. For harsh working environments once considered “man-made no-go zones,” rotary blade remote-controlled lawnmowers have demonstrated irreplaceable dominance.
