Kress Mission RTK 1 1/4 KR173


Meet the Kress Mission RTK KR173, a robotic mower that will give you the perfect lawn and more free time for yards up to 1 1/4 acres.



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. The bullseye navigation algorithm ensures accuracy where lines of sight to the satellites are blocked by trees and buildings. Operated by the MAP™ (Mowing Action Plan) technology, it can maintain each zone independently and efficiently manicures lawns up to 1¼ acre large.

  • 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.
  • Satellite-precise multi-zone management.
  • Patented obstacle avoidance system
  • Follows the shortest possible route to and from the charging station.
  • Auto-leveling blade system adapts to terrain unevenness.
