Herbicide GUSS vs Prospr
Two spraying machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
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.New Zealand-engineered autonomous spraying vehicle for orchards and vineyards, built by Robotics Plus (Tauranga, NZ) and sold/supported today through Yamaha Agriculture, formed when Yamaha Motor completed its acquisition of Robotics Plus in 2025. A hybrid diesel-electric drivetrain (Tier 4 generator + battery pack + independent wheel motors) drives RTK-GPS-guided autonomous spraying with quick-swap Q Series (foliar) and H Series (under-canopy herbicide) sprayers. Commercially deployed in the US, Australia and New Zealand; a published case study (Treasury Wine Estates, NZ) shows two units covering 300 ha of vineyard across eight 15-hour operating days.
Best for: Larger commercial orchard or vineyard operations in the US, Australia or New Zealand — the Treasury Wine Estates case study (two units, 300 ha, NZD 115,000/year net savings after subscription costs) shows the economics working at estate scale, backed by a real Yamaha Agriculture / Croplands / Burrows Tractor dealer network.| Herbicide GUSS Verified 2026-07-19 | Prospr Verified 2026-07-19 | |

| Specifications | ||
| Power source | 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. | Hybrid diesel-electric — Tier 4 diesel generator + regenerative braking + high-capacity battery pack, powering independent electric drive motors at each wheel |
| Required tractor power | Not applicable — self-propelled 4WD/4-wheel-steer platform, not a tractor implement | Not required (self-propelled) — hybrid diesel-electric drivetrain, ~50 kW drive output |
| Dimensions | 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) | 5,240 x 1,950 x 3,600 mm (206 x 77 x 141 in, L x W x H); minimum row spacing 1.85 m (6.07 ft); minimum headland 7.1 m (23 ft), spot-turns around the rear axle |
| Weight | 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.) | 2,000 kg / 4,409 lb (unladen, without payload) |
| Min farm size | 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) | Not disclosed |
| Productivity | 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 | 300 ha (740 ac) covered by two units across eight 15-hour operating days in the Treasury Wine Estates case study — about 1.3 ha/hr (3.2 ac/hr) per unit, up from 1 ha/hr (2.4 ac/hr) with a conventional tractor-mounted sprayer |
| Max speed | Not disclosed | Not disclosed |
| Sensors | 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 | RTK GPS precision navigation; LiDAR + camera sensor fusion for obstacle detection and collision avoidance |

| Native price | Not disclosed | Not disclosed |
| Business model | 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. | Contact-sales / subscription-inclusive model — Yamaha Agriculture's own case study nets savings "after subscription costs" but no purchase price or subscription terms are published; sold direct and through the Yamaha Agriculture / Croplands (AU, NZ) / Burrows Tractor (US) dealer network. |
| Ongoing cost | Diesel fuel, tires, spray consumables (nozzles, pump wear parts) and scheduled maintenance through the GUSS Automation / John Deere dealer network; costs not published | Subscription-style cost referenced in published case studies but exact terms not disclosed; parts and preventative-maintenance kits supplied through the dealer network. |
