ABSTRACT:
A vacuuming apparatus simultaneously vacuums a plurality of parallel rows of plants for removing of insects. A plurality of side-by-side vacuum units are mounted on a mobile support including a tractor-mounted lift to be releasably attached to the front of the tractor. Each vacuum unit includes at least two separate depending intake units located to span two adjacent plant rows. The mobile support includes a frame including a central lift assembly. A parallelogram lift linkage connects the tractor to the lift assembly for vertical positioning of the apparatus. Hydraulical power rams are connected to a tractor driven hydraulic source for control of the position of the apparatus from the tractor. The mobile support frame may include pivoted end frame members, each supporting a vacuum unit and a pair of vacuum inlets. The end frame members are pivoted up and over the ends of the frame for over-the-road travel of the vacuuming apparatus. Releasable support legs support the vacuuming apparatus on the ground when disconnected from the tractor.
