Garford Farm Machinery · United Kingdom

Long-established tractor-mounted vision-guided weeder — video image analysis at 30 frames/second locates each individual plant and steers rotating in-row weeding discs around it, killing weeds between rows AND between plants within the row to ~8 mm of the stem. The 2025-season Robocrop AI upgrade adds green-on-green recognition fusing colour, infrared and depth imaging. Like One Smart Spray, this is AI-driven intelligence on a conventional tractor implement, not a standalone robot.

Best for: Transplanted vegetable growers (lettuce, brassicas, celery) and sugar-beet farms replacing hand-weeding gangs or herbicides with camera-guided mechanical in-row weeding on their existing tractor.
SPAPPERI N.T. S.R.L. · Italy

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.

EU context
CE markingCE marked for EU sales; UKCA for the UK marketNot disclosed — no CE-marking statement found for the SA-AI on Spapperi's site, its brochure, or the dealer-contact page
Machinery RegulationTractor-mounted implement under the EU machinery regime; operator remains in controlNot 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 subsidyMechanical/herbicide-free weeding supports CAP eco-scheme and organic conversion measuresNot 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
