Kress KR172 Mission RTKn

RTK without base station hardware. The proprietary antenna network removes installation friction; autonomy comes at subscription cost and satellite signal dependence.

OWNERSHIP

Living with it.

Antenna network stability is the bottleneck; mower hardware and blade mechanics perform predictably in documented conditions.

RTK positioning reliability documented across 2+ years of European deployments; network availability and signal strength remain the limiting factor. No major firmware regression reported; blade wear accelerates in dense turf. Seasonal storage required in temperate climates.

What goes wrong · not yet documented independently

The independent record is still forming. Failure modes are listed once an outside source reports them.

Upkeep routine
Monthly12×/yr
Charging station contact cleaning and dock inspection.
Seasonal4×/yr
Blade inspection; replace rather than sharpen, since grinding removes the coating and weakens a blade that runs unattended. Replacements are sold in multipacks. · Winterization (cover or indoor storage in cold climates); spring restart and app connection check.
Yearly1×/yr
Seasonal blade replacement and charging station thorough cleaning.

CautionHigh-speed blade hazard: Rotating blade up to 3,600 RPM. Keep pets, children, and hands clear during operation.

NoteNetwork-dependent operation: Mower cannot mow if RTK network is unavailable or account subscription lapses.

Common questions

What people actually ask.

5 answered
OperationDo I need to bury a perimeter wire for the Kress KR172?
No. RTKn uses satellite positioning instead of boundary markers. You define the mowing area through the app; the mower respects virtual boundaries without physical installation.
OperationWhat if my property loses RTK signal temporarily?
The mower switches to inertial navigation and odometry and keeps working until a clear satellite connection is available again. Kress lists this dead reckoning as the mechanism for mowing under shade, so a canopy that interrupts the signal does not end the run. Sustained absence of network coverage, rather than a passing gap, is what stops autonomous operation.
CompatibilityDoes the KR172 need a base station, an antenna or a network subscription?
No. Kress delivers the RTKn correction signal over its own network, which is why the machine ships without a customer-side antenna, beacon or base station, and Kress’s US materials disclose no separate fee for network access. The published US MSRP is $2,499.99. The mower carries a 4G modem for that connection and an anti-theft system with GPS tracking.
OperationCan the KR172 handle slopes and thick Bermuda grass?
Kress rates the machine to a 40 percent maximum slope. Thick grass and wet conditions reduce traction; standard turf fares better than dense annual grasses.
OwnershipWhat parts need seasonal maintenance on the KR172?
Blade replacement (6-12 months depending on use), charging station cleaning (monthly), and winterization in cold climates (perennial storage indoors or under cover).
