Retrofit your existing onion harvester with real-time yield mapping. Designed for Top-Air Topper Loader, Univerco Rider, Asa-Lift (Grimme), Dewulf and Simon machines.
Request a DemoOnions are a precision-irrigation, precision-fertility crop. Yield maps let you see whether weak patches are soil, water, disease pressure or variety — and plan rotation accordingly.
Yellow, red, white, sweet, long-day and short-day varieties — one kit, no configuration changes.
Mass flow measured after topping and cleaning stages — log marketable onions, not gross lifted volume.
Live tonnage tracking helps you stage drying floors, curing barns and packing line deliveries.

A complete retrofit kit for bulk-crop harvesters — load cells, sensor controller, telemetry module and GPS antennas. Install on your onion harvester without dealer involvement.
Load cells mount on the elevator structure; cab module handles GPS, processing and cellular data. Same hardware platform as our potato kit — sized for onion harvester flow rates.
