Reach street trees, planters and green infrastructure from the safety of the cab
Hydraulically controlled watering arms for councils, estates and contractors that need accurate placement, repeatable water volumes and practical reach around parked vehicles, verges and public spaces.
Designed around route-based irrigation
For teams responsible for living assets across difficult public sites
The most valuable gain is not simply reach. It is the ability to place water accurately, work from a mobile carrier and document a repeatable maintenance programme.

Put the water where it is needed without moving the whole vehicle into the planting area
The FS 3000 combines hydraulic reach, cab control and configurable spray heads. Optional dosing and reporting add consistency where contracts or planting specifications require evidence.
Reach around obstacles
Hydraulic swivel and arm adjustment help the operator reach over kerbs, behind parked vehicles and into planting that cannot be approached directly.
Match the delivery pattern
Use a soft brass shower head for sensitive root zones or the adjustable PowerJet for stream, cone or mist delivery.
Record repeatable doses
Flow Control can automate defined quantities, hold preset volumes, monitor tank content and report watering events with GPS position.
From tank to root zone
A watering arm is one part of a complete mobile irrigation system
The carrier, tank, pump, controls, bracket and nozzle must be considered together. The correct package depends on route length, dose, access and the hydraulic services available.
Match the carrier and mounting frame
Confirm tractor model, linkage or bracket, axle capacity, ballast, hydraulic valves and transport dimensions before selecting the arm.
Size tank, pump and hose for the route
Calculate total litres per round, refill points, pump delivery and pressure rather than selecting tank capacity in isolation.
Select the head and control level
Choose gentle shower or variable PowerJet delivery, then decide whether manual operation, electric control, radio remote or measured dosing is required.

Choose the working scale first, then build the controls and delivery package
The FS 3000 is the directly published compact-tractor product. The HTG 4000 route supports heavier-duty configurations. Flow Control and nozzle choices can then be added around the operational requirement.

Pricing note: public prices are read from the linked Kersten product pages after load where possible. Embedded values remain as fallbacks. Prices exclude VAT and do not represent a complete fitted system; brackets, nozzle, controls, pump, tank, hoses, electrical work, delivery and commissioning can materially change the quotation.
Build the complete configuration
Six decisions determine whether the system works efficiently on your route
The watering arm itself is only the visible part of the installation. These package choices should be resolved during fitment review.
1. Carrier and mounting
Confirm the exact tractor, mounting position and frame.
- Cat. 1 / Cat. 1N or municipal interface
- Front axle load, ballast and stability
- Folded height and transport envelope
2. Hydraulics and control
The FS 3000 requires four double-acting hydraulic services unless an appropriate control package is specified.
- Tractor flow and pressure
- Electric control box or radio remote
- Flow-control valve where required
3. Water source and delivery
Tank, pump, dose and refill logistics must match the number of assets on the route.
- Litres per tree or planter
- Total shift demand and refill points
- Pump capacity, filtration and hose size
Responsible professional operation
Plan the carrier, moving arm, water load and public interface together
A long hydraulic arm operating beside roads and occupied spaces introduces genuine clearance, stability and visibility risks. Manufacturer instructions and a task-specific risk assessment remain controlling.
- Use trained operators and inspect hydraulic hoses, pins, controls and locking points before work.
- Confirm axle loads, ballast and stability with the tank full and the arm at maximum outreach.
- Maintain clearance from people, traffic, buildings, overhead services and street furniture.
- Use an exclusion zone or traffic-management measures where the arm enters public or vehicle space.
- Fold, secure and verify the transport position before road travel.
- Check mirrors, cameras, lighting and operator sight lines for the complete carrier configuration.
- Control pressure and flow to avoid soil washout, runoff, damaged planting or water entering the carriageway.
- Use suitable water quality, tank hygiene, filtration and backflow controls for the intended source and application.

Practical specification questions
Before you request a watering-arm quotation
These answers summarise the published Kersten product information. The final quotation, carrier instructions and current manuals control the supplied configuration.
What is the reach of the FS 3000 watering arm?
The published FS 3000 specification gives a total arm reach of 3,500 mm and spray coverage of up to 7,000 mm. Actual working access still depends on the carrier, mounting position, site geometry and safe operating clearance.
What is the difference between the FS 3000 and HTG 4000 ranges?
The FS 3000 is the documented sub-compact and compact-tractor system with 3.5 m arm reach. Kersten's urban-tree article positions the HTG 4000 as the heavier-duty option, describing an 8 m reach and a 50 litre-per-minute pump configuration. Final selection should be confirmed against the carrier, tank, pump and route requirements.
Which spray head should I choose?
The brass shower head is intended for a softer flow around sensitive planting and root zones. The PowerJet nozzle provides adjustable power-jet, cone and mist patterns where a more targeted or variable delivery is required.
Can the operator control the arm from the cab?
Yes. The FS 3000 product page lists electric control-box and radio-remote options for the four arm movements. The correct control package and any required flow-control valve must be matched to the tractor's hydraulic output.
What does the Flow Control option add?
The published Flow Control package supports defined watering quantities, three preset volumes, monitoring of adjustable tank content and online reporting with GPS position and watering records.
Does the watering arm include the mounting frame, nozzle and controls?
Do not assume so. The live FS 3000 page presents the nozzle, control unit and compatible bracket as required selections. The final quotation should identify the arm, mounting interface, control system, nozzle, pump, hoses and any lighting or reporting options.
What must be checked before fitting a watering arm to a tractor?
Confirm front-linkage or mounting compatibility, hydraulic valve requirement and flow, electrical supply, axle loads, ballast, transport height, folded dimensions, visibility, tank and pump arrangement, hose routing and the carrier manufacturer's limits.
Is a site demonstration recommended?
Yes. A demonstration or fitment review helps confirm reach around parked vehicles and street furniture, spray pattern, flow, stability, visibility and the practical route time before procurement.
