GUSS vs Thorvald
Two spraying machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
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.Norwegian autonomous UV-C robot that replaces fungicide sprays for powdery mildew control — working at night in UK tabletop strawberries (used by 13 leading growers, around 20–30% of the national tabletop crop) and California vineyards, where over 150 Thorvald 3.0 units ran the 2025 season. Delivered as a service rather than a machine sale, with a vineyard-specific model launched for 2026.
Best for: Larger tabletop strawberry and wine-grape operations in Saga's service regions (UK, US) wanting to cut fungicide programmes without buying or operating robots themselves.| GUSS Verified 2026-07-18 | Thorvald Verified 2026-07-17 | |
