The hydraulic pivotable weed brush (OKBZ) from Kemp is developed for removing weeds. The hydraulically driven brush effectively removes weeds. The weed brush is suitable for (mini) loader, (mini) excavator, tractor, and forklift.
Advantages
Construction
Due to changes in legislation regarding the use of chemical agents for weed control, Kemp has developed a weed brush. This weed brush removes weeds in an environmentally friendly way and serves as a good alternative to the use of pesticides.
The hydraulically swiveling weed brush (OKBZ) is equipped with a hydraulically swiveling construction. The pivot point is placed close to the vehicle, enabling a large swivel range of approximately 70 degrees to the left and right. This allows the brush to be positioned far from the vehicle while maintaining good visibility of the brush during operation. This makes precise work along edges, sidewalks, walls, and other obstacles possible.
The hydraulically swiveling design uses two hydraulic cylinders, which move the brush under hydraulic pressure.Â
The weed brush is hydraulically powered. The rotating movement of the brush mechanically dislodges weeds from the surface.
The weed brush features a pendulating construction, allowing the brush to follow the contours of the ground. This ensures continuous contact with the surface, and in the case of uneven terrain of approximately ± 15 cm, there is no need to adjust the height. Additionally, the angle of the brush can be adjusted by raising or lowering the frame, enabling a more or less aggressive operation.
The OKBZ is equipped with one brush with 44 steel cable bundles and has a diameter of 750 mm. The weight of the hydraulically swiveling weed brush is approximately 200 kg.
Execution
The hydraulically swiveling weed brush (OKBZ) can be attached to a (mini)loader, (mini)excavator, tractor, or forklift, provided the minimum oil flow is 25 liters per minute.
Two hydraulic functions are required to operate the weed brush:
one function for rotating the brush and one function for hydraulically swiveling the brush.
The OKBZ comes standard with interchangeable plates.

Explanation of options:
OKBF: Swiveling rubber flap
The weed brush can optionally be equipped with a rubber flap to block loose weed and dirt. (See image) The rubber flap is adjustable in multiple positions and can be used on both sides.
OKBVA800/1000: Extended arm (800/1000 mm instead of 650 mm)
The weed brush can optionally be equipped with an extended arm of 1,000 or 800 mm instead of the standard 650 mm. With this extended arm, the brush can be placed further beside the vehicle, creating a larger working range. This is especially useful when brushing along edges, curbs, walls, or other obstacles where extra distance between the vehicle and working area is desired. (See image)
OKBKS: Edge cutting knife
The edge cutting knife ensures well-finished edges along, for example, grass fields and pavements. The knife is equipped with a robust obstacle protection in the form of a heavy spring, preventing damage upon contact with obstacles. Additionally, the edge cutting knife is hydraulically foldable via a cylinder for extra convenience. Mounting takes place on the right side of the machine.
OKBKM: Mechanical tilt head adjustment
With this option, the brush can be mechanically tilted up to 15 degrees to the left or right. By tilting the brush, it can work more aggressively on the surface, making it more effective against stubborn weeds. The tilt angle can easily be mechanically set to multiple positions. (See image)
OKBKH: Hydraulic tilt head adjustment
With this option, the brush can be hydraulically tilted up to 15 degrees to the left or right. This allows the brush's operation to be easily adjusted while working, without the driver needing to dismount. By hydraulically tilting, the brush can be used more aggressively on the surface, effectively removing more stubborn weeds. (See image)
OKB1000: Steel cable brush diameter 1,000 mm, 44 bundles (Min. oil flow: 30 L.)
With this option, the weed brush is equipped with a steel cable brush with a diameter of 1,000 mm, featuring 44 bundles. The larger diameter allows for a wider range and longer lifespan of the brush, as it wears out less quickly. For proper functionality, this brush requires a minimum oil flow of 30 liters per minute.
OKBNY750: Nylon brush diameter 750 mm, 20 replaceable tufts (Min. oil flow: 25 L)
With this option, the weed brush is equipped with a nylon brush with a diameter of 750 mm, featuring 20 replaceable tufts. The main advantage of this design is that individual tufts can be easily replaced when they are worn out, keeping maintenance costs lower and extending the brush's usage duration. For proper functionality, this brush requires a minimum oil flow of 25 liters per minute.
OKBNY1000: Nylon brush diameter 1,000 mm, 24 replaceable tufts (Min. oil flow: 30 L)
With this option, the weed brush is equipped with a nylon brush with a diameter of 1,000 mm, featuring 24 replaceable tufts. The advantage of the replaceable tufts is that worn parts can be easily replaced individually, limiting maintenance costs and extending the brush's lifespan. For proper functionality, this brush requires a minimum oil flow of 30 liters per minute.
OKBSU: Spray / mist unit
The spray unit is an additional feature for the weed brush, enabling water to be sprayed onto the working area during brushing. Moistening the surface helps reduce dust formation and prevents loose weeds and dirt from dispersing. Additionally, water can help loosen stubborn dirt and weeds better, improving the brush's performance and resulting in a neater outcome.
DL: Pressureless return connection
A pressureless return connection ensures that hydraulic oil can flow back to the vehicle without back pressure. This prevents overheating of the hydraulic system and reduces wear on the hydromotor.
OKBO: Overpressure / run-down valve
With this option, the weed brush is equipped with an overpressure and run-down valve. This valve protects the hydraulic system against excessive pressure and ensures controlled spin-down of the brush after the hydraulics are switched off.
OKBE: Electric operation of rotation and swiveling
With this option, a single hydraulic function can switch between rotating the brush and swiveling the brush. By means of an electric switch from the cabin, it is easy to toggle between both functions without the need for an additional hydraulic connection on the vehicle.
OKBEE: Electric operation of rotation, swiveling, and tilting
With this option, the rotation, swiveling, and tilting of the brush can be electrically operated. Using an electric switch, it is easy to select between these functions without needing multiple hydraulic functions on the vehicle.
OKB3XE: Electric operation of rotation, swiveling, tilting, and edge cutting knifeÂ
This option allows the rotation, swiveling, tilting of the weed brush, and operation of the edge cutting knife to be electrically controlled. Using an electric switch, it's easy to toggle between these functions, while requiring only a limited number of hydraulic functions.
OKBJ: Joystick with magnetic base and cable for operation
With this option, the weed brush is equipped with a joystick to operate the machine's additional functions. The joystick features a magnetic base, allowing it to be easily mounted in a suitable place in the cabin. The operation is via a cable, ensuring reliable and direct control of the functions.Â
