Water pump attachment for petrol brush cutter GEKO 28 mm shaft, 9 fluted cutter insert

Attachment water pump designed for petrol brush cutters by GEKO. This accessory connects to a 28 mm drive shaft and uses a 9-flute cutter insert to convert the trimmer’s rotational motion into a simple mechanical pump. It transfers water for light irrigation, washing and small drainage tasks without requiring a separate motor, making it a practical add-on for fieldwork, garden maintenance and temporary on-site water movement when paired with compatible petrol brush cutters.

Advantages

The unit mounts directly to the cutter head and relies on the brush cutter’s engine for power, eliminating the need for an additional power source. Its 28 mm shaft coupling and 9-flute insert provide consistent mechanical engagement for steady water transfer. The design is compact and lightweight for easy transport and quick installation, and the simple mechanical construction ensures low maintenance and uncomplicated operation in outdoor environments.

How to use

Install the water pump attachment by securing it to the brush cutter’s cutter head and aligning the 28 mm shaft coupling according to the manufacturer’s mounting instructions. Ensure the 9-flute insert is correctly seated and all fastenings are tightened.

Usage recommendations

Avoid running the pump dry for prolonged periods and clear debris from the intake to maintain performance. Perform routine inspection of fasteners and the insert after use, and store the attachment clean and dry to prevent corrosion.
