ICARO X4 vs Mini GUSS
Two spraying machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
Italian hybrid diesel-electric robot from Free Green Nature (Colle Umberto, Treviso — coordinated by parent Maschio Gaspardo S.p.a.) that patrols vineyards autonomously and folds out UV-C panels to actively prevent powdery mildew, downy mildew and botrytis, triggered by an onboard weather station ("the Commander of ICARO X4") reading conditions favourable to infection. It is a prevention system, not a curative treatment, and the manufacturer does not publish independent field-performance data — chemical-reduction figures found are vendor-stated.
Best for: Vineyard growers on a single contiguous block up to roughly 10-15 ha who want to cut fungicide/pesticide spray rounds against powdery mildew, downy mildew and botrytis by substituting or supplementing them with UV-C light treatment.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.| ICARO X4 Verified 2026-07-19 | Mini GUSS Verified 2026-07-19 | |

| Specifications | ||
| Power source | Hybrid — electric drive motors with a 2-cylinder Kohler diesel range extender | 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) |
| Required tractor power | Not required (self-propelled hybrid unit) | Not applicable — self-propelled 4WD/4-wheel-steer platform, not a tractor implement |
| Dimensions | Approx. 3085 x 1550 x 1150-2700 mm (L x W x H, UV panels raised); track width ~1500 mm; turning radius ~900 mm; rated for slopes over 15% (per AgTecher/RobotToday listings — not confirmed on the manufacturer site) | 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) |
| Weight | Not disclosed | 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 |
| Min farm size | Not disclosed | Not disclosed as a number; GUSS markets the Mini GUSS at commercial vineyard/orchard/berry scale, not hobby-farm scale |
| Productivity | Up to 10-15 ha coverage per unit for preventive treatment (property layout, slope and soil-dependent); up to 72 continuous hours of operation before refuelling/recharging | 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) |
| Max speed | 2 km/h | Not disclosed |
| Sensors | RTK positioning (centimetre-level, works without satellite signal per vendor); 4 AI-equipped cameras for pedestrian/obstacle detection; SIL2-certified radar; integrated weather station (wind, temperature, humidity, dew point, rainfall) driving an infection-risk algorithm that triggers treatment | GPS, LiDAR and onboard vehicle sensors for autonomous row navigation and obstacle avoidance (agtecher.com; consistent with the GUSS family's published navigation stack) |
| Price & model | ||
| Price (EUR) | Not disclosed | ≈€261,000 (converted from the agtecher.com USD listing; not independently confirmed by the manufacturer) |
| Native price | Not disclosed | $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) |
| Business model | Direct inquiry/quote purchase — Free Green Nature assesses a vineyard's coverage via drone survey before pricing; no price is published (a €115,000 indicative figure circulates on the AgTecher directory only — not manufacturer-confirmed). The company is actively recruiting agricultural-machinery dealers and service centres (no established dealer network found) | 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). |
| Ongoing cost | Kohler diesel range-extender fuel and servicing; UV panel and weather-station upkeep — costs not published | 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. |
| Key outcome | ||
| Best verified result | Chemical fungicide/pesticide use in treated vineyard blocks up to -70% (vendor-stated; not confirmed on the manufacturer's own site, which states only a qualitative "reduction or elimination of pesticides") · vendor | Chemical and water use with the Smart Apply option up to 50% chemical and water savings on average (vendor figure) · vendor |
| EU context | ||
| CE marking | Not disclosed — no CE marking statement found on the manufacturer site or in trade coverage | Not disclosed — no CE-marking evidence found on gussag.com; the manufacturer's own dealer locator lists only US and Australia coverage |
| Machinery Regulation | No explicit compliance statement found; the machine is marketed and sold within the EU (Italy), so would fall under Regulation (EU) 2023/1230 autonomous-machine provisions if placed on the market | Not applicable — no evidence Mini GUSS has been placed on the EU market |
| CAP subsidy | Fungicide/pesticide-reduction positioning may support IPM-linked CAP eco-scheme measures, though no direct CAP reference found in manufacturer materials | 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 |
