Kress KR238EF MasterSeries RTKⁿ Robotic Mower

Designed for Premier Sports Turf Management

The Kress KR238 EF MasterSeries RTKⁿ stands at the forefront of autonomous robotic mowers for professional sports fields and large commercial lawns. Purpose-built for groundskeepers and turf managers who require championship-level uniformity across vast surfaces, this robotic mower maintains up to 88,000 m² within 48 hours, making it exceptionally suited for stadiums, training complexes or multi-pitch facilities.

Reel-Quality Cutting at Scale

At its core, the KR238 EF features a robust 24.5″ (62 cm) cutting width and fifteen razor-sharp blades capable of trimming grass to a remarkably low height of 10 mm with ±1 mm precision. The terrain-following, auto-levelling cutting deck adapts to ground contours in real time, delivering a consistent cut and reducing the risk of scalping over undulating ground. The result is a clean, uniform finish across greens, fairways and sports pitches.

Centimetre-Level Precision with RTKⁿ Guidance

Kress RTKⁿ technology enables the KR238 EF to perform with repeatable, centimetre-level accuracy, entirely wireless and without the need for an on-site antenna. Where GNSS signals may be disrupted, proprietary sensor fusion integrates V-SLAM, inertial measurement and odometry, ensuring seamless navigation even near tree lines or structures. This robust system allows for intelligent path planning (MAP™) and seamless transition between zones, so the mower efficiently covers large and complex plots.

Advanced Sensors and Safety Systems

Operator and pitch safety is prioritised via six ultrasonic sensors, tri-camera (stereo and AI), two time-of-flight (ToF) sensors and a bump sensor, enabling rapid detection and navigation around players, obstacles or equipment. The KR238 EF is equipped with Wi-Fi, Bluetooth and 4G for real-time monitoring, schedule adjustments and fleet management from anywhere via the dedicated app.

Durable, Connected and Theft-Resistant

Built to withstand unpredictable weather (IPX5 water protection), the mower also features anti-theft technology, a PIN code lock and integrated rain sensors. Charging is swift, with a 60-minute cycle restoring its high-capacity 60V, 16.6Ah battery for up to 120 minutes of mowing per charge.

Comprehensive Package and Expandable Capability

The KR238 EF comes supplied with one charging base, a full set of installation tools and 150 replacement blades, making it immediately ready for professional use. Additional dedicated accessories are available to further enhance and customise performance – please contact Sims Garden Machinery for recommendations based on your grounds’ specific requirements.
