The sweeper is designed for attachment to agricultural machinery, wheel loaders or construction machinery. The Optimal 1600 sweeps yards, roads, car parks, silo slabs and stables without leaving any residue. The height can be adjusted via a slotted hole and a lever. By pulling up the collection trough, free sweeping is also possible without dismantling the trough. With a sweeping angle of more than 90 degrees, the entire sweepings fall out of the tray without leaving any residue. The third guide wheel ensures stable running and prevents the machine from rocking.
