Disc Weeder
Twin cutting discs powered by individual hydraulic motors and mounted on moveable, suspended arms are the key to the new "Speedweeder" invented by Spencer Jackson, Te Kauwhata, New Zealand.
Towed behind a small tractor, the Speedweeder rides on two small transport wheels. The operator sits facing forward directly behind the tractor and manipulates the two weeding arms back and forth and in and around row crops, eliminating the need for hand weeding around high value fruit and vegetable crops, or around shelterbelts.
Each disc, about 10 in. across, is fitted with teeth that dig out weeds, slicing them out below ground. The discs turn at variable speeds from 30 to 1,000 rpm's, depending on soil types. A smaller disc is available for more delicate crops.
The Speedweeder sells for about $1,700. A larger model with two seats and two pairs of discs is also available.
