The most efficient on the market

Sensor 400/34

Globally patented sensor technology makes the Heatweed Sensor 400/34 the most cost-effective high-capacity weed control machine on the market. The Sensor 400/34 has very low both energy and water consumption - plus equally low exhaust emissions.

It can be mounted on various implement carriers. The machine comes with a hand-held weed lance and an 800-litre water tank.

  • Much more economical water and energy consumption with patented sensor-based weed control (documented at over 70%)
  • 100% water with no additives apart from decalcification liquid (natural product)
  • Automatic temperature control (+/- 0.4 oC) ensures a stable water temperature and consistent weeding results
  • Low water consumption per m2 means that water has to be topped up less frequently, leaving more time for weed control
  • Inaccessible areas can be treated with hand lances
  • Sturdy, reliable and weatherproof
  • Can be used throughout the season in any weather
  • Comfortable, safe and simple operation from cab
  • Optional integrated filter system for use with surface water.
  • No damage to road surfaces, street furniture or private property
