S Series
The conventional Stoll. The machine the range was built on, first released in 2010.
Ready to work.
The S Series is where Stoll Boomsprays started. Our first broadacre S Series sprayer was released in 2010, built around the philosophy that still drives every machine we make: simple, strong, proven.
It's the Stoll for growers who want a strong, straightforward trailed sprayer that's easy to run, easy to service and made to be worked — with technology options available when you want them.
Choose your S Series
Every S Series shares the same standard equipment. What changes is the tank, the boom widths, and the chassis underneath.
Built for medium-sized operations.
The S3 gives you the strength and proven design of the S Series in a compact 3,000 L machine. Simple to operate, easy to maintain and built with the same heavy-duty construction found throughout the Stoll range.
The S3 chassis and drawbar are laser cut from a single sheet and folded to form a C-section, providing high strength with less weight while allowing the chassis and drawbar to flex. Heavy-duty twin leaf trailing arms help provide a smooth ride for the boom and chassis.

Heavy-duty twin leaf trailing arms and airbag suspension provide a smooth ride to help protect the boom and chassis. The S6 also features the larger front platform covered with safety perf for storage of chemical drums, hoses and equipment, with a convenient fold-down access ladder.

More capacity. Built to cover country.
The S8 combines an 8,000 L tank, 30 m to 42 m boom options, airbag suspension and our hydraulic floating drawbar system to create a large-capacity sprayer designed for a smooth, stable ride.
The S8 drawbar is connected to the chassis via two hydraulic rams plumbed into a nitrogen accumulator. This creates a suspension system for the drawbar, further improving the ride of the sprayer.

Two chassis platforms
S3–S5
Chassis and drawbar laser cut from a single sheet and folded to form a C-section — high strength with less weight, while allowing the chassis and drawbar to flex.
Heavy-duty coil spring suspension with heavy-duty twin leaf trailing arms, and airbag suspension as an option. Hypro 9303C pump at 416 L/min.
S6–S10
A heavy-duty, fully welded box-section steel chassis with airbag suspension and heavy-duty twin leaf trailing arms. Hypro 9306C pump at 784 L/min, aluminium breakaways and a larger front platform for drums, hoses and equipment.
The S8 and S10 add the hydraulic floating drawbar: two hydraulic rams plumbed into a nitrogen accumulator, creating a suspension system for the drawbar.
No fuss. No stress. No trouble.
Fitted as standard across the S3, S4, S5, S6, S8 and S10.
ISO rate & section control
ISO automatic rate control and automatic section control system to suit your existing GPS equipment.
Tank
UV-stabilised polyethylene tank with a large sump for complete drainage and a smooth interior for easy chemical decontamination. The forward-sloping tank with front sump is designed to keep weight on the tractor as the sprayer empties. Tank and chassis design provides high ground clearance while retaining a low centre of gravity.
TeeJet controls
Quality TeeJet controls including 430 Series 12V electric ball valves with stainless steel balls, electric regulating valve and 801 flowmeter.
Hypro pump
Hydraulically driven Hypro pump fitted as standard. The plumbing allows the Hypro to be used to fill the main tank, eliminating the need for a standalone firefighter or transfer pump.
425 L flush tank
Plumbed for quick and easy flushing of the pump and boom. Positioned low in the chassis to maintain a low centre of gravity and help keep weight on the tractor as the main tank empties.
Filtration
High-capacity fill filter ensures water is filtered before entering the tank, followed by twin ARAG 330 Series pressure filters, with the first being self-cleaning.
Agitation
Turbo agitator fitted as standard to keep chemical thoroughly mixed.
Chemical induction hopper
60 L drop-down induction hopper with high-flow agitator nozzle, drum rinse nozzle and hopper flush nozzle. Designed to make transferring liquids and powders quick, clean and easy.
Clean water / hand wash
15 L hand wash tank with integrated detergent bottle.
Wheels & axles
Large single tractor wheels provide better flotation and reduced ground compaction, with a heavy-duty axle fitted as standard.
Poly mudguards
Poly mudguards with large mudflaps fitted as standard.
Double-sided electric fencelines
Electric fenceline nozzles fitted to both sides, allowing the operator to stay clear of fences and trees while still spraying around them.
Nozzles
TeeJet non-drip nozzle bodies mounted behind the boom for protection, with stainless steel nozzle brackets. TeeJet AIXR nozzles of your choice are fitted as standard.
Boom lift
Large parallelogram boom lift provides fast, smooth height adjustment. Hydraulic cylinders are plumbed into a nitrogen accumulator to provide boom suspension.
Boom control
Hydraulic fold, individual hydraulic wing tilt and hydraulic bi-fold allow the outer wing to be hydraulically folded in to spray at a narrower width.
Boom construction
All-steel, single-truss design with twin chains for excellent boom stability and to help eliminate yaw stress.
Hydraulics
Quality Hydac hydraulic manifold and control valves, with nitrogen accumulators used on the tilt cylinders and boom lift cylinders for boom suspension.
Tank fill
Top-mounted bottom fill fitted as standard.
Tank rinse
Tank rinse nozzles fitted to the main tank and plumbed to automatically operate when filling the main tank with clean water, helping reduce foaming.
Sight tube
External sight gauge for accurate tank filling.
Simple plumbing
High-quality Australian-made chemical-grade hose throughout. Section valves are positioned on the boom centre rack rather than at the front of the sprayer, reducing unnecessary hose lengths for easier decontamination, neater installation and faster boom on/off times. The front work zone features just two clearly labelled taps. No fuss. No stress. No trouble.
Finish
Trailer and boom are sandblasted, primed with high-quality zinc shield primer and then powder coated for excellent chemical resistance and a hard, durable finish.
Road light kit
LED trailer lights, oversize sign and rotating beacon.
