Greenfield Robotics Weed Cutter

Greenfield Robotics operates a fleet of small autonomous weed-cutting robots as a per-acre service for soybean and specialty-crop growers across the US Great Plains. The robots move between crop rows at night and during low-traffic daytime hours, cutting weeds below the soil surface with mechanical blades — entirely without herbicides. Greenfield's service model means growers pay per acre per pass, with no capital expenditure on equipment, maintenance, or storage. The company focuses on soybean fields where in-row herbicide use is tightly constrained, and where physical removal is the only compliant option in organic or transitional fields. Multiple passes per season can eliminate weed populations over time, reducing the long-term weed seed bank in the soil.
