Farming GT vs AX-1
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.Norwegian ultra-precision weeding robot for open-field vegetables — an AI vision system detects individual weeds and a patented Single-Drop nozzle (SDT) fires one micro-droplet of herbicide directly onto each weed at 6x6mm resolution, cutting herbicide input by a manufacturer-claimed average of 96.6%. Independently tested by Wageningen University & Research at over 99% spray-drift reduction (Dutch DRT99, the system's highest class), and commercially deployed since 2021 across Norway, Sweden, Germany, the Netherlands and Australia, with a 2025 Kubota partnership now expanding EU dealer-network sales.
Best for: Open-field vegetable and root-crop growers (carrots, onions, beets, celery/celeriac, spinach, salads, parsley and similar) in Norway and neighbouring EU markets who still spray herbicide and want to sharply cut volume and drift without switching to purely mechanical or laser weeding.| Farming GT Verified 2026-07-16 | AX-1 Verified 2026-07-18 | |

| Specifications | ||
| Power source | Battery-electric · 24+ h runtime | Electric drive with a small onboard petrol generator (per GOFAR robotics database; not itemized on the manufacturer's own site) |
| Required tractor power | Not required (self-propelled, no tractor or driver) | Not required (self-propelled autonomous unit) |
| Dimensions | Track width variable 138–225 cm (convertible in ~15 min) | Approx. 220 x 215 x 150 cm (third-party listing; not published by Kilter) |
| Weight | Not disclosed | 280 kg dry / 365 kg wet (GOFAR database; distributed to minimise soil compaction) |
| Min farm size | Not disclosed | Not disclosed |
| Productivity | Up to 10 ha per 24 h, unsupervised day and night | Not disclosed — third-party estimates conflict (0.33-1 ha/hr) and Kilter does not publish a figure |
| Max speed | Not disclosed | Up to 2 km/h (third-party listing; not published by Kilter) |
| Sensors | AI multispectral plant/stem detection from 1 cm size · row guidance without GNSS dependency · collision and rain sensors | AI vision with a deep-learning neural network for real-time weed/crop detection at 6x6mm targeting resolution; RTK-GNSS (dual-antenna) and IMU for autonomous navigation (third-party listing) |
| Price & model | ||
| Price (EUR) | Not disclosed | ≈€130,000 |
| Native price | Not disclosed | ≈€130,000 (third-party: Future Farming robot database — Kilter quotes individually) |
| Business model | Primarily weeding-as-a-service; direct machine sale on request | Buy — direct from Kilter AS (Langhus, Norway) via a consultative sales process (farm details submitted for a quote; no public price list), or through regional distributors such as Croplands (Australia). A Kubota partnership (announced at Agritechnica 2025) is expanding dealer-network sales in Germany and the Netherlands through 2025-2026. |
| Ongoing cost | Service pricing not published | Herbicide/bio-herbicide refills (any crop-registered agrochemical usable in a boom sprayer, e.g. pelargonic acid); Single-Drop nozzle module (SDT-N2) wear parts. Specific service cost figures not disclosed. |
| Key outcome | ||
| Best verified result | Herbicide use −100% · vendor | Spray drift vs. a conventional reference sprayer More than 99% spray-drift reduction — qualifies for DRT99, the highest class in the Dutch drift-reduction classification system · independent |
| EU context | ||
| CE marking | CE-conform per vendor (Machinery Directive 2006/42/EC compliance stated) | No explicit CE-marking statement found on Kilter's public materials; the AX-1 is sold and in active commercial/pilot use in EU member states (Sweden, Germany, Netherlands) and passed independent Dutch DRT99 spray-drift certification (WUR/TCT) |
| Machinery Regulation | Vendor states 2006/42/EC compliance; 2023/1230 transition status not published | Not explicitly addressed by the manufacturer; as an autonomous field-spraying machine placed on EU markets, would fall under the autonomous-machine provisions of Regulation (EU) 2023/1230 if formally assessed |
| CAP subsidy | Herbicide-free mechanical weeding aligns with eco-scheme goals; no formal listing verified | Precision spot-application (manufacturer-claimed ~95-96.6% herbicide reduction) supports CAP eco-scheme and integrated-pest-management / pesticide-reduction objectives |
