Farming GT 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.
Stuttgart-built autonomous hoeing robot that identifies crops from the 1 cm cotyledon stage across 100+ validated crops and weeds mechanically around the clock — 40+ robots working 1000+ fields, offered mainly as weeding-as-a-service.
Best for: Vegetable and row-crop growers in Germany and neighbouring EU countries with high hand-weeding costs who want herbicide-free in-row hoeing without buying hardware.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.| Farming GT Verified 2026-07-16 | Inter-Plant Weeder SA-AI Verified 2026-07-19 | |

| Specifications | ||
| Power source | Battery-electric · 24+ h runtime | Tractor PTO-driven hydraulics — dedicated independent hydraulic circuit per weeding element, shared oil tank |
| Required tractor power | Not required (self-propelled, no tractor or driver) | Not disclosed — Spapperi specifies PTO-driven hydraulic transmission but publishes no minimum tractor horsepower figure for the SA-AI |
| Dimensions | Track width variable 138–225 cm (convertible in ~15 min) | Not disclosed — modular frame (1-4 rows, single or double planting-row spacing); overall width/length vary by configuration |
| Weight | Not disclosed | Not disclosed |
| Min farm size | Not disclosed | Not disclosed — no hectare threshold published; the multi-row tractor-mounted design targets commercial vegetable/root-crop operations |
| Productivity | Up to 10 ha per 24 h, unsupervised day and night | 4,500-8,500 plants/hour per row, depending on in-plant spacing |
| Max speed | Not disclosed | Not disclosed |
| Sensors | AI multispectral plant/stem detection from 1 cm size · row guidance without GNSS dependency · collision and rain sensors | 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) | Not disclosed | Not disclosed |
| Native price | Not disclosed | Not disclosed |
| Business model | Primarily weeding-as-a-service; direct machine sale on request | 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 | Service pricing not published | 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 | Herbicide use −100% · vendor | In-row weeding labour Vendor testimonial states each row unit replaces about 10 manual workers · vendor |
| EU context | ||
| CE marking | CE-conform per vendor (Machinery Directive 2006/42/EC compliance stated) | Not disclosed — no CE-marking statement found for the SA-AI on Spapperi's site, its brochure, or the dealer-contact page |
| Machinery Regulation | Vendor states 2006/42/EC compliance; 2023/1230 transition status not published | 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 | Herbicide-free mechanical weeding aligns with eco-scheme goals; no formal listing verified | 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 |
