Vulcan vs Robovator
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, vision-guided intra-row hoeing implement from Danish manufacturer F. Poulsen Engineering — a camera above each row spots individual plants and hydraulically swings weeding knives out and back around them, removing weeds between plants without touching the crop. Commercially sold since the early 2010s and independently trialled in US vegetable production; configurable from 5 to 31 rows and adjustable to 25–75 cm row spacing.
Best for: Vegetable, sugar-beet and row-crop growers with a suitable PTO tractor who want camera-guided mechanical in-row weeding to cut herbicide use and hand-weeding labour, across a wide range of farm scales (5- to 31-row configurations).| Vulcan Verified 2026-07-19 | Robovator Verified 2026-07-18 | |

| Specifications | ||
| Power source | Tractor-drawn, PTO-driven implement (not self-propelled) | Tractor-mounted implement, PTO-driven hydraulics (~1 hp per row) |
| 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 | 3-point-hitch mounted; requires tractor PTO shaft speed of at least 420 rpm (hydraulic pressure and lamps cut out below ~360 rpm) |
| 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 | Configurable 5 to 31 rows; row spacing adjustable 25–75 cm (9–30 in); US-market spec sheet lists 6–12 lines per bed with 60–84 in bed spacing |
| 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) | 700 kg (1,500 lb) base weight |
| 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 |
| 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 | Roughly 1.5–2 acres/hour depending on soil and plant conditions (per Pacific Ag Rentals, US distributor); manufacturer-stated field speed 2–8 km/h (1.2–5 mph) |
| Max speed | 1.5-4 mph | 2–8 km/h (1.2–5 mph) |
| 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 | One plant-detection camera per row for image-based crop location, functions in low light; automatic self-centring side-shift (±40 cm range, engages after ~1 m of travel) |
| 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 F. Poulsen Engineering (Denmark) and via distributors, including Agri Evolution (Netherlands, EU) and Pacific Ag Rentals (Salinas, California, western US) |
| 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 | Wear parts (weeding knives/blades, camera lens care), hydraulic fluid and PTO shaft maintenance; no software subscription published |
| 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 | Intra-row weed removal vs. a standard cultivator +18 to +41 percentage points · independent |
| EU context | ||
| CE marking | Not confirmed — no CE-marking evidence found; all documented deployments and dealer/service coverage are US-only (Southwest US) | No CE-marking statement found in the manufacturer's public materials, so compliance is listed as not confirmed — although CE marking is legally required to place machinery on the EU market and F. Poulsen actively sells within the EU (Denmark, and via Netherlands distributor Agri Evolution) |
| 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 | Tractor-mounted implement falling under the EU Machinery Regulation (EU) 2023/1230; the tractor operator remains in control at all times |
| CAP subsidy | Not applicable — US-based product with no EU sales presence, outside EU CAP eco-schemes | Herbicide-free/reduced mechanical in-row weeding supports CAP eco-scheme and organic-conversion measures |
