Instructed by the Kress RTKn network, it navigates your lawn with centimeter-level accuracy. No need for boundary wire or fixed reference antenna to be installed on the lawn. Operated by the MAP™ (Mowing Action Plan) technology, the mower works in parallel lines, as an experienced landscaper would. It efficiently manicures lawns up to 4½ acres large. Bullet Points Satellite-guided — no perimeter wire installation. Centimeter-level accuracy without the need for a fixed antenna in the lawn. Systematic coverage in parallel lines for maximum mowing efficiency. Large cutting capacity (13.8 in) blade system to cover large areas with fewer passages. Double layer blade system for high-density and slightly overgrown grass. Satellite-precise multi-zone management. TeamWork technology for operating more than one robot inside the same working area. Follows the shortest possible route to and from the charging station. Auto-leveling blade system adapts to terrain unevenness. In-Hub encoded gearless drive motors for smooth delivery of torque and quiet operation.
