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.

Inertial navigation
An inertial navigation system is typically formed of three orthogonal accelerometers and three orthogonal gyroscopes that measure tri-axial linear acceleration and angular velocity, respectively. Inertial navigation, or dead reckoning, is based on motion-sensing devices connected to a computer that constantly computes the position, velocity and orientation of a moving object. For moving objects that rely on external references, e.g. satellite navigation or computer-vision navigation, inertial navigation is used when such external references are temporarily unavailable. Inertial navigation is subject to cumulative errors. Accuracy depends on the precision of its motion-sensing devices and, most importantly, on the algorithm that computes data.
While today we think of dead reckoning in terms of satellite navigation, this term has been around since at least 1613, as recorded in the Oxford English Dictionary. Historically, dead reckoning was a fundamental technique in marine navigation, used to estimate a ship’s position by advancing a known position using estimations of speed and course. Navigators employed clever devices like the ‘chip log’ to gauge a vessel’s speed through the water.
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.

Auto-leveling blade system
The floating blade deck automatically adjusts to uneven terrain, ensuring a consistent cut while preventing turf scalping.
Less time emptying, more time mowing
The bushels spec doesn’t tell the full story, it’s the fill rate that counts. Our advanced LiftStream™ airflow maximizes bag capacity, reducing emptying frequency by up to 33% and keeping you on the move

Say goodbye to half-empty bags and frequent stops
Mowing efficiency is redefined with Kress LiftStream™ — an advanced aerodynamic design that stretches from blade to bag. The blade’s flaps create a powerful upward airflow that propels grass clippings through the spiral bagging tunnel of the deck up to the very back of the bag, ensuring it fills completely and evenly every time.
Large cutting capacity
The dual-disc ensures efficient coverage of large areas with fewer passes.
Dual-layer razor blades
Engineered on separate planes, the blades effortlessly manage high-density and overgrown grass.
Electronic cut height adjustment
Grass cutting height can be adjusted with a simple slider in the app for a tailored turf finish.
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.
In-hub gearless motors
Kress direct-drive motors ensure smooth, trouble-free running, season after season.
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.
