Conver weed harvesters have been developed specifically to remove water plants and/or floating debris from waterways and lakes. Floating plants such as duckweed (Lemnoideae) and common water hyacinth (Eichhornia Crassipes), as

well as rooted plants such as waterweed (Elodea) and many other varieties, can be harvested. The differences between the machines concern their working depths, cutting widths and storage capacities.
