Aquatic Vegetation Removal

Category:

Dredge Plant

Description:

The versi-dredge is a portable hydraulic dredge fitted with a special "weedmaster" cutterhead to

remove hyacinth and other vegetation from a pond or lake. It is self-propelled with a Starwheel

drive system (patent pending). It can also dredge bottom sediments as a conventional small

hydraulic pipeline dredge.

The versi-dredge equipped with a weedmaster cutterhead can clear 2 to 4 ha per 12-hr work day

depending on the density and maturity of weed population. It cuts weeds into 8- to 10-cm lengths

so they can be pumped through a discharge pipe. It is more effective than mechanical dredges.
