Hydro-Raking
 Hydro-raking is a common technique used for the physical
removal of small scale infestations of aquatic plants. Allied
Biological’s hydro-rake uses a 4’ - 8’ wide rake with a backhoelike attachment to collect and remove weeds, debris, and organic
material. Equipped with high-speed paddle wheels and a limited
draft, this machine is ideal for shallow waters.
Hydro-rakes are most often used to clear small areas around
docks, ramps, channels, and wimming areas, although they can
help deepen shallow areas. The hydro-rake can also be equipped with a solid bucket with drains
for dredging operations.
 The hydro-rake does not have on board storage so if it is necessary to
dispose of plant material at a distant off-load site, the conveyor
system on a weed harvester is utilized to transport the material. Rate
of productivity varies greatly depending on the type of material and
shoreline disposal points, but often ranges from 0.25-1.5 acres per
day.
Hydro-raking is ideal for removal of:
• Floating islands
• Cattails
• Waterlilies
|
• Leaf accumulation
• Phragmites
• Snags |
