ARA vs Herbicide GUSS
Two spraying machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
Tractor-drawn smart sprayer that treats each plant individually with centimetre precision.
Best for: Growers cutting herbicide/pesticide spend hard while keeping an existing tractor fleet.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.| ARA Verified 2026-07-16 | Herbicide GUSS Verified 2026-07-19 | |

| Specifications | ||
| Power source | Tractor PTO + hydraulics; onboard AI compute | Diesel — 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 power | 80 hp minimum | Not applicable — self-propelled 4WD/4-wheel-steer platform, not a tractor implement |
| Dimensions | 6.00 m working width folded to 3.0 m transport | 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) |
| Weight | 1,900 kg | 12,460 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 size | 30 ha | Not 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) |
| Productivity | Up to 4 ha/hour | 90-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 speed | 7 km/h working | Not disclosed |
| Sensors | High-res cameras · per-plant recognition · section control | GPS + 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 |

| Business model | Buy · lease · contractor revenue-share options | 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 cost | €3,200/yr software + agronomic subscription | Diesel fuel, tires, spray consumables (nozzles, pump wear parts) and scheduled maintenance through the GUSS Automation / John Deere dealer network; costs not published |

| CE marking | CE marked (2022) | Not disclosed — no CE-marking evidence found; confirmed commercial deployment is US and Australia only |
| Machinery Regulation | Compliant — Regulation (EU) 2023/1230 | Not applicable — no evidence Herbicide GUSS has been placed on the EU market |
