Vulcan vs Field Friend (Feldfreund)
Two weeding machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
US (Salinas, CA) tractor-drawn precision weeder using onboard cameras and computer vision to mechanically remove weeds in-row without herbicide. Original venture-backed maker FarmWise wound down independent operations on 1 April 2025 after raising $65M but failing to reach profitability; three days later, produce processor Taylor Farms (itself a prior FarmWise investor and long-time customer) acquired the FarmWise business outright to keep the Vulcan line running. As of mid-2026 Vulcan is still actively sold and field-supported — not discontinued — through an exclusive dealer partnership with RDO Equipment Co. across the Southwest US.
Best for: Large-scale US vegetable growers (multi-thousand-acre operations, the kind Taylor Farms and Barkley Farms run in Salinas/Yuma) who want to cut hand-weeding crew costs on lettuce, brassica, or tomato beds and can absorb a six-figure implement purchase plus annual service contract.Modular AI mini field robot from Zauberzeug (Havixbeck, Münsterland) — a ~100 kg tracked platform under 1 m³ that uses onboard camera AI (the "Zauberzeug Robot Brain" edge-compute unit) to distinguish crops from weeds and mechanically remove them, including deep-rooted weeds. Offered both as a pay-per-hour weeding service (no machine purchase) and as a development platform; trade press reported roughly €20,000 for the machine with tools up to ~€5,000 extra. Winner of the Münsterland Innovation Award 2023/24.
Best for: Small-scale German vegetable and row-crop growers, market gardens and research users who want camera-guided mechanical in-row weeding without a big capex — pay per hour of weeding done.| Vulcan Verified 2026-07-19 | Field Friend (Feldfreund) Verified 2026-07-17 | |

| Ongoing cost | Reported ≈US$45,000/yr service & support package per unit (trade-press figure); consumable weeding-blade wear parts; software/AI model updates delivered via the onboard edge-learning system | Service model includes maintenance; battery cycling and tool wear if machine is owned |
| Key outcome | ||
| Best verified result | Weeding cost, large multi-region vegetable operation ≈US$550,000 reduction in weeding costs in a single season (customer-reported figure, cited by trade press at the time Taylor Farms was a FarmWise customer, before its 2025 acquisition of the company) · vendor | Herbicide use Camera-guided mechanical single-weed removal, herbicide-free, including deep-rooted weeds · vendor |
| EU context | ||
| CE marking | Not confirmed — no CE-marking evidence found; all documented deployments and dealer/service coverage are US-only (Southwest US) | German-built machine operating commercially in Germany; CE status not independently verified |
| Machinery Regulation | Not applicable found — no EU placement on the market; would fall under Regulation (EU) 2023/1230 autonomous-machine provisions if the Vulcan were ever sold into the EU | EU-built; conformity route under the EU machinery regime not published |
| CAP subsidy | Not applicable — US-based product with no EU sales presence, outside EU CAP eco-schemes | Herbicide-free mechanical weeding supports CAP eco-scheme and organic goals |
