KR 238 - MasterSeries RTKⁿ 20 acre

$54,999.99Price

The Kress MasterSeries KR238 redefines unmanned turf management for golf courses and professional sports fields. Engineered to maintain championship-quality surfaces at scale, it mows up to 20 acres in 48 hours, delivering the consistency, precision and reliability demanded by professional turf managers. Auto-levelling cutting decks continuously adapt to ground contours, maintaining a precise cut while eliminating scalping across undulating terrain. Combined with Kress razor-sharp blades, the system produces clean, reel-like cuts with ±1 mm accuracy, ensuring exceptional visual consistency, playability and turf health—even at cutting heights as low as 10 mm. At the heart of the KR238 is Kress RTKⁿ technology, delivering centimeter-level positioning accuracy. When GNSS signals become unreliable, the system seamlessly switches to sensor fusion, combining V-SLAM, inertial data and odometry to maintain stable, uninterrupted navigation until satellite reception recovers. A range of dedicated accessories further expands the system’s capabilities, transforming the KR238 into a complete solution for modern professional turf management.
