Precision mowing with RTK

RTK is the state-of-the-art geo-positioning technique that fine-tunes satellite signals for unparalleled accuracy.


Uninterrupted precision under shade

If satellite signals are obstructed by buildings or trees, Kress mowers switch to dead reckoning mode to maintain accurate routing, until a clear satellite connection is available again.


Satellite-guided centimeter-level accuracy

Kress's advanced network of base station antennas transmits precise correction data directly to each mower, ensuring unmatched precision for the cutting of every single blade of grass.


Daily fresh-cut stripes

The new Kress 173 RTKn follows a perfectly parallel line pattern. The result? Impeccably aligned stripes that make your grounds a standout feature of the property. Every day.


Master of complexity

Guided by satellites, the Kress KR173 RTKn excels at navigating complex landscapes and follows even the most tortuous paths from one turf area to another.


Stay in control

The Kress app can handle up to 10 robotic mowers simultaneously. For oversight of extensive grounds maintenance operations, the specialized fleet management app is coming early spring.


Auto-leveling blade system

The floating blade deck automatically adjusts to uneven terrain, ensuring a consistent cut while preventing turf scalping.


Agility meets precision

Kress Obstacle Avoidance System (OAS) ensures the mower navigates with precision around each challenge the terrain presents.


A future-proof investment

Just like your smartphone, Kress robot mowers get automatic over-the-air updates whenever new software is available.


Electronic cut height adjustment

Grass cutting height can be adjusted with a simple slider in the app for a tailored turf finish.


Washable underbody

IPX5 rated, the chassis is designed to withstand the force of a sustained water jet from a hose, making cleaning quick and easy.


Secure and traceable

Kress robot mowers feature real-time geo-location tracking, offering peace of mind with anti-theft monitoring on your smartphone.


Energy-smart on slopes

Kress robotic mowers capture energy as they descend hills, recycling power back into the battery.
