consists of the carrier vehicle (1) and the weed brush (6). The carrier vehicle (1)
has no traction drive, but is pushed forward on the hand rail (2). An internal
combustion engine (3) is attached to the vehicle frame (4). The internal combustion
engine (3) drives a hydraulic motor (5). The hydraulic motor (5) rotates the weed
brush (6). The weeds are removed from the ground with the help of brush elements
on the rotating weed brush (6).

The internal combustion engine supplies the energy for a hydraulic pump (8)
installed in the chassis. The hydraulic pump (8) ensures the circulation of the
hydraulic oil and drives the hydraulic motor (6). The hydraulic motor (6) rotates the
weed brush. Suitable hydraulic fluid can be filled in via the hydraulic oil filler neck
(9).
The uniaxial weed brush is operated or set using various function levers (10) on
the handle (1).
An underbody splash guard (7) prevents material loosened from the floor from
being thrown backwards in the direction of the operator.

hydraulic hoses (1). The brush plate (4) is mounted on the hydraulic motor (2). The
brush plate (4) can be equipped with wire rope braids (5) or a tuft.
By turning the brush plate (4), the brush elements (5) remove the weeds from the
joints. Removed material is caught by a side-mounted splash guard frame with
signal tape (7) and rubber spray flaps (6) attached to it. The splash guard frame (7)
is screwed to the working head (3) via the swivel arm (8).
