Free Green Nature S.r.l. · Italy

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.
GUSS Automation (wholly owned John Deere subsidiary since August 2025) · United States

GUSS Automation's dedicated herbicide sprayer for orchards and vineyards — the same self-driving 4WD/4-wheel-steer platform as base GUSS, but built to spot-spray weeds in row middles instead of spraying the tree/vine canopy, using multiple onboard weed-detection sensors to target individual weeds rather than blanket-spraying. Diesel-powered (John Deere 4.5L 74 hp Stage V engine, no DEF) with a 600-gallon tank and adjustable 15-19 ft breakaway spray booms. Like the rest of the GUSS line it is sold and serviced only through John Deere dealers, confirmed only in the US and Australia, with no EU presence found.

Best for: Large commercial orchard and vineyard operations in the US or Australia (same footprint as base GUSS — almonds, walnuts, pistachios, citrus, stone fruit, wine grapes) wanting to cut herbicide use and weeding labour by autonomously spot-spraying individual weeds in row middles instead of blanket spraying or hand/mechanical weeding.

Specifications
Power sourceHybrid — electric drive motors with a 2-cylinder Kohler diesel range extenderDiesel — John Deere 4.5L 74 hp Stage V engine, no DEF required (manufacturer brochure). A third-party directory instead describes a 3.8L Cummins engine; not confirmed by GUSS Automation, whose own current brochure states John Deere.
Required tractor powerNot required (self-propelled hybrid unit)Not applicable — self-propelled 4WD/4-wheel-steer platform, not a tractor implement
DimensionsApprox. 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)23 ft 6 in long x 6 ft 4 in tall x 8 ft 4 in transport width; 15-19 ft adjustable spray boom width (manufacturer brochure)
WeightNot disclosed12,460 lb (5,652 kg) empty — manufacturer brochure. (A third-party directory cites "5,652 lb", which is actually this same kg figure mislabeled as lb — a units error, not a genuine conflict.)
Min farm sizeNot disclosedNot disclosed as a number; manufacturer brochure markets the GUSS/Herbicide GUSS line at small, medium and large operation scales (its "small scale" case study is still a professional commercial grower, not a hobby farm)
ProductivityUp 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/recharging90-gallon fuel cell gives approximately 13-14 hour run time; one operator can monitor/supervise up to 8 GUSS/Herbicide GUSS machines at once; manufacturer case study cites refill downtime cut from a typical 45 minutes to about 3 minutes
Max speed2 km/hNot disclosed
SensorsRTK 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 treatmentGPS + LiDAR + vehicle sensors for autonomous navigation (manufacturer states GPS alone is unreliable beneath tree canopy, hence the added sensor stack); multiple onboard precision weed-detection sensors trigger targeted spot-spraying instead of blanket application; GUSS Safety Vest disables drive mechanics when a nearby worker's vest is detected
Price & model
Price (EUR)Not disclosedNot disclosed
Native priceNot disclosedNot disclosed
Business modelDirect 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 or pay-for-service, sold and serviced through GUSS Automation (Kingsburg, California — a wholly owned John Deere subsidiary since August 2025) and John Deere dealers, confirmed in the US and Australia. GUSS Automation publishes no unit price; a third-party ag-tech directory (unconfirmed by the manufacturer) cites an indicative $301,000-$400,000 depending on configuration.
Ongoing costKohler diesel range-extender fuel and servicing; UV panel and weather-station upkeep — costs not publishedDiesel fuel, tires, spray consumables (nozzles, pump wear parts) and scheduled maintenance through the GUSS Automation / John Deere dealer network; costs not published
Key outcome
Best verified resultChemical 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
Herbicide application — spot-spray vs blanket application
Multiple onboard weed-detection sensors trigger targeted spot-spray only where weeds are actually present · vendor
EU context
CE markingNot disclosed — no CE marking statement found on the manufacturer site or in trade coverageNot disclosed — no CE-marking evidence found; confirmed commercial deployment is US and Australia only
Machinery RegulationNo 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 marketNot applicable — no evidence Herbicide GUSS has been placed on the EU market
CAP subsidyFungicide/pesticide-reduction positioning may support IPM-linked CAP eco-scheme measures, though no direct CAP reference found in manufacturer materialsNot applicable — no EU/CAP-linked deployment found
