Echo TM-850S GPS RTK Robotic Mower

Compact Precision for Professional Lawns

The Echo TM-850S GPS-RTK brings advanced robotic mowing to smaller sports fields and managed lawns. Using GPS-RTK guidance, it delivers perfect, repeatable strip patterns without boundary wires. With 2 floating heads and 6 stainless steel blades, it produces an even, mulched finish while maintaining efficient energy use.

Accuracy Without Boundaries

Guided by GPS-RTK with Wisenav® technology, the TM-850S works to within 2 cm accuracy. Operators can define zones, patterns, and no-go areas directly through the Echo web portal or mobile app. The mower navigates precisely without physical boundaries, making setup faster and more flexible for multi-field or irregular sites.

Made for Schools and Sports Facilities

Compact yet capable, the TM-850S is built for smaller sports pitches, school grounds, and training areas up to 30,000 m². Its 52 dB noise level allows continuous mowing during lessons or overnight without disruption, and its 25 kg chassis ensures gentle operation on turf, even in damp conditions.

Smart Management and Reliable Support

Through the Echo portal and app, teams can monitor mowing progress, check maintenance logs, and adjust settings remotely. Groundtech provides full UK installation, RTK base setup, and calibration support, ensuring every TM-850S performs reliably from day one.

Recommended Accessories

• GPS-RTK Base Station (Wi-Fi or 4G)

Looking to cover more ground?

Step up in range and productivity

If your site exceeds 30,000 m² or you manage multiple pitches, move up to the Echo TM-1050 GPS-RTK. It offers longer runtime and extended capacity with the same GPS accuracy.

Need something simpler or wired?

Choose a compact wired option

For smaller single-field installations where a wired setup works best, the Echo TM-1000 delivers professional autonomous mowing at a lower entry point.
