Foam-Covered Powered Weed Wiper
At the recent Northwest Ag Expo in Portland, Ore., FARM SHOW discovered a powered weed wiper made by Agriweld Inc., Monmouth, Ore. It uses nozzles to spray foam concentrate onto a rotating roller, which aggressively wipes the foam chemical solution on weeds.
The weed wiper uses a special roller with a carpet-like covering that's driven by a hydraulic motor. Chemical is mixed with a foam concentrate and applied to wiper rolls through Teejet nozzles. As the roller rotates it rubs against a backing which turns the liquid on the roller into foam. Roller speed can be adjusted using a flow control valve. The chemical/foam solution is pumped by a 25-gal. poly tank.
"Rotating the roller prevents dripping and does a better job of wiping chemical on weeds," says inventor Craig Pope. "You can see streaks on the roller where the weeds rub the foam off, which makes it easy to monitor the amount of chemical that's available on the wiper at all times. The low positioning of the roller applies chemicals to the undersides of leaves."
Available in widths from 12 ft. to 30 ft. A basic 30-ft. unit sells for $5,155; one equipped with a hydraulic power unit and foam marker sells for $7,067.
