Element vs Vulcan
Two weeding machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
US solar-powered autonomous weeding robot from Aigen (Redmond, WA) that eliminates weeds mechanically with AI-guided ground strikes — no herbicide. The current gen2 platform (launched April 2025) widened its working crops to cotton, soy and sugar beet and runs a mesh-networked robotic "crew"; roughly 50 units were in field trials in North Dakota/Minnesota (Grand Farm) and California (Bowles Farming) through 2025; the 2024 and 2025 preorder rounds sold out in a day, and 2026 orderability is not independently confirmed.
Best for: US row-crop growers (cotton, soy, sugar beet) wanting to cut herbicide spend and pursue organic certification, and willing to run a multi-robot fleet rather than a single machine (Aigen's own example — ~5 robots to cover 160 acres / 65 ha in a season).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.| Element Verified 2026-07-18 | Vulcan Verified 2026-07-19 | |

| Specifications | ||
| Power source | Solar-electric — onboard solar panel with battery backup (gen2 carries ~50% more solar capacity than gen1); no fuel used | Tractor-drawn, PTO-driven implement (not self-propelled) |
| Required tractor power | Not required (self-propelled) | 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 |
| Dimensions | Not disclosed | 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 |
| Weight | Not disclosed | 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) |
| Min farm size | Not disclosed | 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 |
| Productivity | Illustrative fleet example from Aigen: ~5 robots to cover 160 acres (65 ha) in a season; a single robot's seasonal capacity is 20-40 acres depending on weed density | 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 |
| Max speed | Not disclosed | 1.5-4 mph |
| Sensors | Onboard stereo depth-vision cameras and onboard AI (gen2 has 4x the compute of gen1) for row-following and weed identification; mesh network lets robots coordinate as a "crew" | 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 |
| Price & model | ||
| Price (EUR) | ≈€44,000 (indicative conversion) | ≈€555,000 (+ ≈€39,000/yr service) — indicative conversion only; Vulcan is not sold or priced in the EU |
| Native price | $50,000 | 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 |
| Business model | Buy — $50,000 per robot (confirmed on TechXplore, quoting Aigen). A working deployment is typically several robots (Aigen's own illustrative example — ~5 robots per 160 acres / 65 ha). 2024/2025 preorder rounds sold out in a day; 2026 orderability not independently confirmed. | 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) |
| Ongoing cost | Not disclosed — Aigen has not published ongoing service/software costs on its own materials. One third-party business-model summary cites an additional ~$20,000 per-fleet coordination/software fee, but that figure could not be confirmed on any primary or trade-press source, so it is not carried into this field. | 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 |
| Key outcome | ||
| Best verified result | Herbicide spend and organic-certification eligibility Zero-herbicide mechanical weeding in Grand Farm (ND) trial deployment — growers avoid herbicide spend and can pursue organic certification / premium pricing · independent | 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 |
| EU context | ||
| CE marking | No CE marking evidence found — no EU sales or service presence identified (US-only — ND, MN, CA field trials/deployments) | Not confirmed — no CE-marking evidence found; all documented deployments and dealer/service coverage are US-only (Southwest US) |
| Machinery Regulation | Not applicable — not placed on the EU market | 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 |
| CAP subsidy | Not applicable — US-only company; no CAP relevance found | Not applicable — US-based product with no EU sales presence, outside EU CAP eco-schemes |
