Berky NEREUS 240 Amphi

Amphibious mower boat typ 6450

Whether on land or water, the BERKY NEREUS 240 AMPHI is versatile. The BERKY NEREUS 240 AMPHI combines boat and vehicle in one machine. The manoeuvrable and compactly built machine thus not only allows work in the middle of the water, but also in the hard-to-reach marginal areas, in shallow places and in swampy areas.

Wide range of applications for effective water maintenance

The possible work applications of the amphibious mowing boat are as versatile as the areas of use. With the swivelling outrigger arm, mowing, collecting flotsam and desilting are easy tasks. Not only floating plants Lemma (duckweed) and water hyacinths are effectively removed, but also rooting plants such as waterweed or comparable plant species are removed by the mowing boat. Rent or buy our mowing boats for watercourse cleaning and removal of aquatic plants.
