The Voyager KR804 is a stand-on, RTK-guided commercial mower with a 152 cm (60-inch) deck and a reported 19 acres per charge — roughly triple the capacity of the 40-inch KR800 Voyager Kress sells today. It is reported to be on sale in the Netherlands now; a US price has not been disclosed.
Kress presented the Voyager KR804 at GroenTechniek Holland in Biddinghuizen on 16 September, according to an on-site report by the Dutch trade title Tuin en Park Techniek. A Kress-supplied announcement carried by TurfNet the following day says the machine, branded “Voyager 60” for North America, will make its US debut at Equip Expo in Louisville, Kentucky, 20–23 October 2026.
The KR804 is the larger sibling of the KR800 Voyager, the 40-inch autonomous mower Kress lists in the US at $59,999.99 [Manufacturer-stated — voyager.kress.com, checked 18 Sep 2026]. Where Kress specifies the KR800 at 10 kWh and up to 7 acres per charge, the two outlets report the KR804 at 38 kWh and up to 19 acres (about 76,000 m²) on a charge, mowing up to 2.5 acres per hour. AI Mower News has not tested either machine, and Kress has not yet published a KR804 specification page; every KR804 figure below is as reported by the named outlet.
What the outlets report about the KR804
- [Reported by TurfNet and Tuin en Park Techniek] 152 cm / 60-inch cutting deck; cutting height 30–140 mm (1.25–5.5 in in the US release).
- [Reported by TurfNet] Up to 2.5 acres per hour; up to 19 acres per charge; 38 kWh energy capacity; operating speed 2.2–9 mph; maximum slope 25 degrees.
- [Reported by Tuin en Park Techniek] Approximately 76,000 m² per charge; weight approximately 850 kg.
- [Reported by both] RTK positioning with no boundary wire; obstacle detection by cameras, a LiDAR sensor and ultrasonic sensors.
- [Reported by both] A rear stand-on platform with two control levers. An operator rides the machine once to teach a property’s boundaries, paths and no-go zones; it then mows the mapped area autonomously. The same platform allows manual mowing.
- [Reported by TurfNet] Kress Commercial app connectivity and a five-year commercial warranty. Kress has not published an operating-hour cap for the KR804; the KR800 warranty is five years or 2,000 hours, whichever comes first [Manufacturer-stated — voyager.kress.com].
Price and availability
- [Reported by Tuin en Park Techniek] Netherlands: €78,999 excluding VAT, available immediately.
- [Unverified — not disclosed] United States: no price published. Kress’s US website and Voyager microsite listed only the KR800 when checked on 18 September [Manufacturer-stated — kress.com]. The US debut is scheduled for Equip Expo, 20–23 October [Reported by TurfNet].
MasterSeries KR238 also shown, with a sports-field version and 2027 attachments
Kress also showed the MasterSeries KR238 at the same event. This is not a new model: the golf version, KR238G, is already listed on Kress’s US site at $43,999.99 [Manufacturer-stated — kress.com, checked 18 Sep 2026]. What is new from GTH is a sports-field configuration, European pricing, and an attachment roadmap.
- [Reported by Tuin en Park Techniek] 62 cm cutting width; up to 88,000 m² in 48 hours; 99 kg; three cutting discs with five blades each; a steel rear roller to accentuate stripes and remove dew; cutting height 10–100 mm; stripe widths of 1.5–6 m by mowing adjacent passes in one direction.
- [Reported by Tuin en Park Techniek] Netherlands pricing: sports-field version €30,990 ex VAT; golf version €33,057 ex VAT; both available.
- [Reported by Tuin en Park Techniek] Planned for 2027: a ball collector, a line-marking unit, a magnet bar and a UV light bar intended to treat turf disease. These are stated plans, not shipping products.
Why it matters
The KR804 moves Kress’s commercial autonomy from a 40-inch machine that replaces one operator on a route into deck-width territory occupied by conventional commercial zero-turns. If the reported 19-acre range holds up in the field, it would be the largest per-charge coverage Kress has published for any mower. Independent testing and real-world reports will determine whether the figures hold; AI Mower News will update this record when Kress publishes a KR804 specification page or when field evidence appears.
