The comfort watering arm with a range of up to 8.50 m
Set new standards in municipal and commercial plant care with the Fiedler watering arm. Our watering arms, made entirely of high-quality stainless steel, combine durability with state-of-the-art control technology. With an impressive reach of up to 8.50 m (including water jet), you can easily reach even remote green areas. The 250° swivel range provides an enormous working radius in front of the vehicle, allowing you to water areas directly next to the driver's or passenger door without having to manoeuvre.
No hydraulics? No problem! We think ahead: in addition to classic hydraulic versions, we offer the first fully electric watering arm for all municipal vehicles.
Intelligent control with the FIEDLER FMC
Forget jerky movements. Our proportional CAN-BUS control system guarantees smooth workflows without lag.
The award-winning FIEDLER FMC control system offers you, among other things:
- Precise dosing: flow rate (l/min) or exact individual dispensing at the touch of a button.
- Automation: Save spray arm positions, which the system then moves to fully automatically.
- Relief: Numerous automatic programmes support the driver and increase work safety.
Digital management –
Watering records and route planning
Digitise your workflows with our optional data collection feature. The system proactively supports you in resource planning:
- Planning: Optimise your routes and application rates in advance on your PC.
- Documentation: Create legally compliant pouring records at the touch of a button.
Evaluation: Access all performance data immediately after the route – for maximum transparency towards clients.



Maximum irrigation range:
Long-range nozzles for maximum flexibility
Want to maximise your range when watering large areas? Our state-of-the-art long-range nozzles offer the ideal solution – even in hard-to-reach areas.
Precise control and maximum flexibility
Installation is tailored to your needs: either on the left, right or both sides of the tank system. Thanks to the intuitive joystick control, the nozzles can be operated just as conveniently and precisely with the FMC as our proven watering arm.
Technical highlights for your land management:
- Large swivel range: Benefit from maximum mobility with vertical angles from +21° to -17° and horizontal angles from +65° to -35°.
- Individual spray pattern: The spray pattern of the long-range nozzle can be adjusted in just a few simple steps.

- Winter use: In just a few simple steps, you can convert the system into a highly efficient brine spray system for winter service.
Invest in sustainability and efficiency. Fiedler watering arms are the robust answer to the challenges of modern urban and landscape maintenance.
10 most important FAQs about watering arms
A watering arm (also known as a watering boom or irrigation arm) is a professional attachment for municipal vehicles such as Unimogs, Multicars, tractors or lorries. It is used for the efficient mobile watering of trees, green spaces, hanging baskets and traffic islands. The key advantage is that the driver controls the arm directly from the cab without having to get out or pull heavy hoses.
The use of a FIEDLER pouring arm significantly increases work safety and efficiency:
- One-man operation in flowing traffic: No second employee is required to remain in the danger zone of the road.
- Obstacle clearance: The arm easily reaches over parked cars, fences or crash barriers.
Ergonomics: No heavy lugging of hoses; convenient control via joystick from the driver's seat.
The main difference lies in the superior mobility and future-proof drive technology. While many market standard models often only cover a range of 160° to 210°, the FIEDLER casting arm has a swivel range of approx. 250° as standard . In addition to classic hydraulics, we also offer a fully electric control system that enables more precise movements .
Depending on the variant, operation is via the vehicle control system or a CAN-BUS joystick with colour display (FMC).
- Control: Optionally hydraulic or fully electric for sensitive movements.
Plant protection: The large shower head produces a soft, low-pressure spray ("soft rain"). The water quantity and spray intensity can be precisely adjusted on the control unit to protect young plants and avoid wasting water.
No, not necessarily. We offer two drive concepts:
- Variant A (hydraulic): Uses the existing vehicle hydraulics.
- Variant B (fully electric): This version operates completely independently of the hydraulics. This makes it the perfect solution for electric municipal vehiclesor vehicles that have no or insufficient hydraulic systems of their own.
Yes. With FIEDLER Connect, we offer a modern telematics solution to meet the increasing documentation requirements for local authorities:
- Real-time monitoring of work.
- Legally compliant digital proof of watering for the quantities of water applied.
- Order planning and customer management directly via the system.
