ICARO X4 vs 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 sprayer for orchards and vineyards, now a wholly owned John Deere subsidiary after an August 2025 acquisition that followed a three-year joint venture. GUSS navigates rows itself on GPS + LiDAR with no driver on board, but GUSS/Deere describe this as "supervised" autonomy — one operator monitors and can remotely intervene on up to 8 machines at once from a laptop. The line spans base GUSS (600-gal tank, diesel), Mini GUSS (smaller footprint for vineyards/high-density orchards/berries), Herbicide GUSS (sensor-triggered spot-spray weed control) and a 2024 fully electric option; sold and serviced only through John Deere dealers in the US and Australia, with 250+ units deployed globally as of the 2025 acquisition.
Best for: Large commercial orchard, vineyard and berry operations in the US or Australia (almonds, walnuts, pistachios, citrus, stone fruit, wine grapes) wanting to shrink a multi-tractor spray crew — GUSS's own case study shows a conventional 8-worker, 6-tractor medium-scale crew dropping to 2 workers and 4 GUSS units.| ICARO X4 Verified 2026-07-19 | GUSS Verified 2026-07-18 | |

| Specifications | ||
| Power source | Hybrid — electric drive motors with a 2-cylinder Kohler diesel range extender | Diesel — John Deere 4.5L 173 hp Stage V engine (Tier 3 available for export); Herbicide GUSS uses a 4.5L 74 hp Stage V engine (no DEF); a fully electric variant (Electric GUSS, John Deere KREISEL batteries) launched 2024 |
| 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) | GUSS: 24 ft long x 6 ft 4 in tall x 8 ft 3 in wide (standard tires; 7 ft 6 in narrow / 8 ft 4 in low-impact options). Herbicide GUSS: 23 ft 6 in long x 6 ft 4 in tall x 8 ft 4 in transport width, 15-19 ft adjustable spray width |
| Weight | Not disclosed | GUSS: 11,660 lb empty. Herbicide GUSS: 12,460 lb empty (manufacturer brochure) |
| Min farm size | Not disclosed | Not disclosed as a number; manufacturer brochure markets GUSS at small, medium and large operation scales (its own "small scale" case study is still a professional commercial grower, not a hobby farm) |
| 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 | 90-gallon fuel cell gives approximately 13-14 hour run time; one operator can monitor/supervise up to 8 GUSS machines at once; manufacturer case study cites refill downtime cut from a typical 45 minutes to about 3 minutes |
| 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 for autonomous row navigation; user interface flags position/spray-rate/mobility faults with automatic visual and audible alerts; Herbicide GUSS adds multiple onboard weed-detection sensors for spot-spraying |
| Price & model | ||
| Price (EUR) | Not disclosed | Not disclosed |
| Native price | Not disclosed | Not disclosed |
| 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 exclusively through John Deere dealers in the US and Australia; Herbicide GUSS is also offered as a pay-for-service option alongside outright purchase. No unit price published. |
| Ongoing cost | Kohler diesel range-extender fuel and servicing; UV panel and weather-station upkeep — costs not published | Diesel fuel, tires, spray consumables (nozzles, pump wear parts) and scheduled maintenance through the John Deere dealer network; costs not published |
| 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 | Spray-crew labour and equipment at medium scale 8 workers to 2 workers (75% fewer); 12 pieces of towed/tractor equipment to 4 GUSS units · 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; confirmed commercial deployment is US and Australia only |
| 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 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; case-study savings above relate to US/Australia operations |
