Kress KR172E.A RTK 3000m2 + OAS

The Kress KR172E.A Mission RTKn 3000 + OAS is a wire-free robotic mower built for lawns up to 3,000m². It uses satellite navigation for precision and includes an Obstacle Avoidance System (OAS) to detect and avoid objects in real time. It’s a strong option for gardens with trees, furniture, or other common hazards.

About the Kress KR172E.A Mission RTKn 3000 + OAS

This model runs on RTKn satellite positioning, so it doesn’t need any boundary wire. Once the area is mapped, it follows a defined route across the lawn with tight accuracy. The OAS uses sensors to identify objects and steer around them, reducing the chance of collisions or stoppages during mowing. It’s powered by a quiet, brushless motor and includes dual cutting blades for clean results. The mower docks itself when charging is needed and works on a set schedule through the Kress app. For homes with cluttered gardens or unpredictable spaces, this model handles the job without constant supervision.

Specific Uses for the KR172E.A

• Medium-sized domestic lawns up to 3,000m²
• Gardens with obstacles like trees, play equipment, or benches
• Properties where laying boundary wire isn’t practical
• Users who want low-noise, automated mowing
• Multi-zone gardens with uneven or mixed terrain

FAQs

• Q: What does OAS do? A: The Obstacle Avoidance System uses sensors to detect objects in the mower’s path and change direction automatically.
• Q: Is boundary wire required? A: No, the mower uses RTKn navigation and doesn’t need any wire installation.
• Q: Can it mow complex gardens? A: Yes, it handles multiple zones and irregular layouts through the Kress app.
• Q: Is the mower safe around pets and children? A: Yes, OAS helps it detect and avoid unexpected obstacles during operation.
• Q: How is it controlled? A: Through the Kress Mission app on iOS or Android devices.

Accessories You’ll Need for the KR172E.A

With wire-free navigation and onboard obstacle detection, the KR172E.A is built for more complex residential lawns. A few smart accessories can help simplify setup, protect your investment, and ensure long-term performance — especially in dynamic garden environments.

RTKn Signal Support

To unlock full RTKn accuracy, the mower may require access to a local correction signal. If you’re in a weak signal area, a compatible RTK base station can provide the accuracy needed to keep the mower aligned within a few centimetres.

Charging Station Shelter

A low-profile garage or shelter keeps the charging dock protected from harsh weather and falling debris. It also helps reduce moisture-related wear over time, especially in shaded or exposed gardens.

Spare Blades and Sensor Cleaning Kit

Since the OAS system relies on sensor visibility, we recommend keeping a soft cleaning kit on hand to wipe lenses and sensors. A spare set of blades also ensures uninterrupted mowing during peak growth months.

Temporary Setup Markers

During the digital zone setup process, small flags or markers can help define the mowing area and no-go zones. These are especially useful in gardens with trees, raised beds, or tight pathways. GroundTech can fully install your KR172E.A, including RTK signal setup, zone mapping, and on-site calibration of the Obstacle Avoidance System.
