In orchards or fields of grape vines, weeding in inter-plant spaces may be performed with a mechanical weeder. The weeder may include a frame configured to be propelled by a motorized vehicle. A rotatable weeder unit may be pivotally connected to a pivot arm attached to the frame and a spring may be connected to hold the rotatable weeder unit in a nominal pivotal position relative to the frame responsively to a force exerted by the spring. When encountering a producing plant, the weeder unit may deflect away from the plant thereby precluding damage to the plant. |
