Mini GUSS vs Thorvald
Two spraying machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
California-built (Kingsburg) autonomous orchard/vineyard sprayer — GUSS Automation's smaller sibling to the base Orchard GUSS, built roughly 25% smaller to fit high-density orchard and vineyard rows. Same driverless GPS+LiDAR row navigation and laptop-based fleet supervision as the base machine (one operator can watch up to 8 units), on a 400-gallon tank with interchangeable vineyard and apple/high-density-orchard spray towers rather than the base machine's larger 600-gallon tank. Sold and serviced only through the John Deere/GUSS dealer network in the US and Australia; GUSS Automation is now a John Deere subsidiary following an acquisition confirmed on GUSS's own site.
Best for: Commercial vineyard, high-density-orchard and berry operations in the US or Australia that need a narrower, lower-profile autonomous sprayer than the base Orchard GUSS — its standard height (5 ft 4 in) and 400-gallon tank are sized for tighter row spacing rather than large tree-nut orchards.Norwegian autonomous UV-C robot that replaces fungicide sprays for powdery mildew control — working at night in UK tabletop strawberries (used by 13 leading growers, around 20–30% of the national tabletop crop) and California vineyards, where over 150 Thorvald 3.0 units ran the 2025 season. Delivered as a service rather than a machine sale, with a vineyard-specific model launched for 2026.
Best for: Larger tabletop strawberry and wine-grape operations in Saga's service regions (UK, US) wanting to cut fungicide programmes without buying or operating robots themselves.| Mini GUSS Verified 2026-07-19 | Thorvald Verified 2026-07-17 | |

| Specifications | ||
| Power source | Diesel — Cummins F3.8 173 hp Stage V engine; 77-gallon fuel cell gives roughly 12 hours of runtime (agtecher.com; not listed on gussag.com's own Mini GUSS page) | Battery-electric · 48 V Li-Ion 70 Ah (space for a second battery) · charges from a regular outlet |
| Required tractor power | Not applicable — self-propelled 4WD/4-wheel-steer platform, not a tractor implement | Not required (self-propelled modular platform) |
| Dimensions | 19 ft long x 6 ft wide x 5 ft 4 in tall (standard/transport configuration); 9 ft 2 in tall with the Apple Tower fitted; 9 ft tall with the Vineyard Tower fitted (gussag.com) | Modular platform; configuration-dependent, not disclosed |
| Weight | Approx. 8,800-8,840 lb (3,990-4,010 kg) empty — two secondary listings give close but non-identical figures (agtecher.com: 8,840 lb / 4,010 kg; agricultural-robotics.com: 8,800 lb / 3,992 kg); not published on gussag.com itself | ~200 kg |
| Min farm size | Not disclosed as a number; GUSS markets the Mini GUSS at commercial vineyard/orchard/berry scale, not hobby-farm scale | Not disclosed |
| Productivity | 77-gallon fuel cell gives approximately 12-hour runtime (agtecher.com); one operator can monitor/supervise up to 8 GUSS units at once from a laptop (GUSS fleet-supervision model, per agtecher.com and GUSS company materials) | Fleet-scale service: ~2,500 acres of US vineyard treated; ~20% of UK tabletop strawberry crop |
| Max speed | Not disclosed | Typically under 5 km/h in operation |
| Sensors | GPS, LiDAR and onboard vehicle sensors for autonomous row navigation and obstacle avoidance (agtecher.com; consistent with the GUSS family's published navigation stack) | Autonomous navigation stack; crop-counting cameras (up to 3 million crop counts per robot per night, vendor claim) |
| Price & model | ||
| Price (EUR) | ≈€261,000 (converted from the agtecher.com USD listing; not independently confirmed by the manufacturer) | Not disclosed |
| Native price | $283,660 USD (agtecher.com equipment-marketplace listing — GUSS Automation does not publish Mini GUSS pricing on its own site, same as the sibling base GUSS profile in this catalog; a separate secondary listing (agricultural-robotics.com) gives a bundled $300K-400K range across the whole GUSS/Mini GUSS/Herbicide GUSS family, not Mini-GUSS-specific, which is a loose but not contradictory cross-check) | Not disclosed |
| Business model | Buy, sold and serviced through the John Deere/GUSS Automation dealer network in the US and Australia (gussag.com dealer locator); no Mini-GUSS-specific lease or pay-for-service option was found (contrast Herbicide GUSS, which GUSS does offer as a service option per the sibling base-GUSS profile). | UV-C treatment as a service — Saga deploys, operates and maintains robot fleets; growers pay for treatment rather than buying machines |
| Ongoing cost | Diesel fuel, tires and spray consumables (nozzles, pump wear parts); no published service-cost figures were found. GUSS's own Mini GUSS page notes eligibility for California's CARB FARMER equipment-replacement incentive funding, a US-specific program, not a running cost. | Service fee (not published); no grower-side machine ownership |
| Key outcome | ||
| Best verified result | Chemical and water use with the Smart Apply option up to 50% chemical and water savings on average (vendor figure) · vendor | Fungicide use for powdery mildew −70–100% pesticide use (vendor claim) · vendor |
| EU context | ||
| CE marking | Not disclosed — no CE-marking evidence found on gussag.com; the manufacturer's own dealer locator lists only US and Australia coverage | CE status not published; UV-C units carry light-exposure safety interlocks for night operation |
| Machinery Regulation | Not applicable — no evidence Mini GUSS has been placed on the EU market | Placed on the EU/UK market by Saga Robotics; Regulation (EU) 2023/1230 autonomous-machine provisions apply |
| CAP subsidy | Not applicable — no EU/CAP-linked deployment found; in the US, GUSS's own Mini GUSS page notes eligibility for California's CARB FARMER equipment-replacement incentive program, which is unrelated to EU CAP | Large pesticide reduction supports EU pesticide-reduction and eco-scheme goals (service currently UK/US/NO, not EU-27) |
