Vulcan vs Inter-Plant Weeder SA-AI
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.Tractor-mounted, chemical-free in-row weeder from SPAPPERI N.T. S.R.L. (Città di Castello, Italy; est. 1964). A hydraulic PTO-driven frame (1-4 rows) carries per-row "BOX AI" units — a 3D camera plus AI vision developed with Czech partner Ullmanna — that detect each plant's root and drive independent vertical rotary tillers or fixed knives to weed within the row. Spapperi's own brochure calls it both "SA-IA" and "SA-AI"; the product is marketed via that brochure and lead-gen listings rather than a dedicated page on Spapperi's main site as of this check.
Best for: Commercial vegetable and root-crop growers (Spapperi's own examples include lettuce, cabbage, pumpkin and sugar beet) who already run an appropriately-sized tractor with rear hydraulics and want mechanical in-row weed control without GPS guidance or chemical herbicides.| Vulcan Verified 2026-07-19 | Inter-Plant Weeder SA-AI Verified 2026-07-19 | |

| Specifications | ||
| Power source | Tractor-drawn, PTO-driven implement (not self-propelled) | Tractor PTO-driven hydraulics — dedicated independent hydraulic circuit per weeding element, shared oil tank |
| Required tractor power | Not disclosed as an HP figure; compatible with standard Category II 3-point-hitch tractors, including John Deere 5-Series (V440 model) and 6-Series tractors | Not disclosed — Spapperi specifies PTO-driven hydraulic transmission but publishes no minimum tractor horsepower figure for the SA-AI |
| Dimensions | Single-bed working width 76-84 in (1.93-2.13 m); three-bed (V380/T380) working width reported as roughly 20-21 ft (6-6.4 m); four-bed V440 in 40 in bed spacing | Not disclosed — modular frame (1-4 rows, single or double planting-row spacing); overall width/length vary by configuration |
| Weight | Not disclosed precisely by FarmWise; independent coverage puts the single-bed unit at roughly 3,000 lb (1,360 kg) and the three-bed unit at roughly 7,000 lb (3,175 kg) | Not disclosed |
| Min farm size | Not disclosed; documented deployments are on large multi-thousand-acre vegetable operations (e.g. a 10,000-acre Yuma, AZ/Salinas, CA grower), not smallholdings | Not disclosed — no hectare threshold published; the multi-row tractor-mounted design targets commercial vegetable/root-crop operations |
| Productivity | 25+ acres/day, 3-4+ acres/hour per manufacturer spec sheet; a two-unit Taylor Farms fleet reported covering up to 100 acres in a single week | 4,500-8,500 plants/hour per row, depending on in-plant spacing |
| Max speed | 1.5-4 mph | Not disclosed |
| Sensors | Multiple high-resolution, camera-equipped row units (18 cameras reported on the three-bed unit) plus custom LED lighting for all-lighting and night operation; onboard computer vision and deep-learning models for weed/crop differentiation | 3D camera plus integrated lighting per weeding element ("BOX AI", AI vision by Ullmanna) for day/night plant-root detection; anti-collision sensors on each element arm; central "Power Box" CPU with GPS and internet connectivity |
| Price & model | ||
| Price (EUR) | ≈€555,000 (+ ≈€39,000/yr service) — indicative conversion only; Vulcan is not sold or priced in the EU | Not disclosed |
| Native price | US$645,000 MSRP for the flagship three-bed 80 in Vulcan V380, plus a reported ≈US$45,000/yr service & support package — trade-press reported figures (Farm Progress, The Packer), not published on the FarmWise site; single-bed and 68 in/40 in models are priced lower but not disclosed | Not disclosed |
| Business model | Direct purchase (not RaaS), sold and field-supported exclusively through RDO Equipment Co. dealers across the Southwestern US since a September 2024 exclusive partnership; John Deere Financing and AgDirect financing offered; FarmWise also runs a "try before you buy" trial program (a free 1-week trial, or paid extended 100/250/500-acre trials with credits toward purchase) | Buy — tractor-mounted implement sold direct from Spapperi NT S.r.l. (Città di Castello, Italy); AI vision developed with Czech partner Ullmanna, integrated as Spapperi's "BOX AI - Ullmanna System" |
| 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 | Interchangeable rotary-tiller/knife wear parts; hydraulic oil and PTO-pump upkeep; AI crop models update automatically over the internet (Spapperi states a new crop can be added in about 6 hours) |
| 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 | In-row weeding labour Vendor testimonial states each row unit replaces about 10 manual workers · vendor |
| EU context | ||
| CE marking | Not confirmed — no CE-marking evidence found; all documented deployments and dealer/service coverage are US-only (Southwest US) | Not disclosed — no CE-marking statement found for the SA-AI on Spapperi's site, its brochure, or the dealer-contact page |
| 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 | Not disclosed — would fall under Regulation (EU) 2023/1230 as a mounted implement with AI-driven functions if placed on the EU market; no explicit compliance statement found |
| CAP subsidy | Not applicable — US-based product with no EU sales presence, outside EU CAP eco-schemes | Not disclosed — mechanical/AI in-row weeding removes herbicide use, which is relevant to CAP eco-schemes rewarding reduced chemical inputs, but Spapperi does not tie the SA-AI to CAP explicitly |
