The STIHL SGA 85 cordless sprayer is a professional battery-powered backpack sprayer built for consistent, controlled application across larger working areas. Its 17-litre tank, adjustable 1–6 bar working pressure and comfortable carrying system make it particularly well suited to horticulture, agriculture, fruit growing, viticulture, estates and professional grounds maintenance.
Unlike a conventional manual backpack sprayer, the SGA 85 uses a battery-powered pump to maintain spraying pressure. This removes the need for repeated hand pumping and helps deliver a more consistent application throughout the job.
The SGA 85 is part of the professional STIHL AP Battery System. It is supplied as a tool only unless a battery-and-charger package is specifically selected.

Professional cordless spraying without manual pumping
The STIHL SGA 85 replaces the manual pumping action required by a conventional backpack sprayer with an electrically powered pump. Once switched on, the system maintains spraying pressure while the operator controls the flow from the spray gun.
This is particularly useful when treating larger areas, where frequent manual pumping can become tiring and may produce uneven pressure. The battery-powered system helps maintain a more consistent output from the start of the job to the end.
Adjustable pressure from 1 to 6 bar
Working pressure can be adjusted between 1 and 6 bar using the rotary control on the sprayer. A pressure gauge on the spray gun allows the operator to monitor the selected pressure while working.
The variable pressure setting allows the SGA 85 to be adapted to different approved products, nozzle configurations and application requirements. Lower pressure can be selected for controlled treatment, while higher pressure provides additional output where the task requires it.
Always follow the instructions, approved application rate and safety requirements supplied by the manufacturer of the liquid being used.
Large 17-litre tank
The 17-litre maximum filling capacity reduces the number of stops required when treating larger sites. It provides considerably more working capacity than a small hand-held sprayer while retaining the mobility of a backpack machine.
A filling strainer helps prevent larger particles from entering the tank, while additional filtration within the system helps protect the pump and spray attachment from blockages.
Comfortable carrying system
A full sprayer can become heavy, so the SGA 85 uses an individually adjustable carrying system designed to distribute the load across the operator’s back and shoulders.
The padded backrest and adjustable straps improve comfort during longer jobs. The sprayer also incorporates a carrying handle for lifting and short-distance transport when the tank is empty.
Controlled spraying from the lance
The spray gun includes a pressure gauge, control handle and lockable trigger. This gives the operator direct control over when liquid is released and makes it easier to maintain a steady application while moving through the working area.
The standard machine is fitted with a brass hollow-cone nozzle. STIHL also offers additional spraying accessories and nozzle options for different approved applications.
Professional STIHL AP System power
The SGA 85 operates on the professional 36V STIHL AP System. The same compatible battery platform can power a wide range of STIHL professional cordless chainsaws, hedge trimmers, brushcutters, blowers, lawn mowers and other equipment.
Customers who already own compatible AP System tools may therefore be able to use an existing battery and charger, reducing the cost of adding the SGA 85 to their equipment fleet.

Which battery should I use with the STIHL SGA 85?
STIHL currently recommends the STIHL AP 200 S battery for the SGA 85. It provides a practical balance between working weight, capacity and runtime.
STIHL states a maximum working time of up to 1,000 minutes with the AP 200 S. Actual runtime will vary according to the selected pressure, operating conditions, temperature, battery condition and working method.
For regular professional use, we recommend pairing the AP 200 S with an AL 301 or faster compatible charger. View the available STIHL battery chargers at Masseys.
Suitable applications
The STIHL SGA 85 is primarily intended for professional treatment in areas such as:
- Horticultural sites and nurseries
- Orchards and fruit-growing operations
- Vineyards and viticulture
- Agricultural land and crop-growing areas
- Forestry and plantation management
- Large estates and landscaped grounds
- Professional grounds maintenance
Only use liquid products that are approved by their manufacturer for application through a pressurised sprayer. Always follow the product label, dilution rate, personal protective equipment requirements and relevant regulations.
Why Masseys recommends the STIHL SGA 85
Masseys recommends the STIHL SGA 85 for professional users who need more capacity, pressure control and consistency than a manually pumped backpack sprayer can comfortably provide.
Its main advantage is not simply that it is cordless. The battery-powered pump removes the repeated pumping action and maintains a controlled pressure throughout the application. This can reduce operator fatigue and help produce a more even treatment across larger working areas.
We particularly recommend the SGA 85 when:
- A 17-litre tank is needed to reduce refill stops
- Consistent pressure is important across a larger site
- The machine will be used regularly rather than occasionally
- The operator already owns STIHL AP System batteries
- Low machine noise and no direct exhaust emissions are beneficial
- Professional dealer advice, spare parts and after-sales support are important
Is the STIHL SGA 85 the right sprayer for you?
Choose the SGA 85 when you need a high-capacity professional sprayer, adjustable pressure up to 6 bar and the convenience of the STIHL AP battery platform.
For larger domestic gardens, small estates or less intensive work, the STIHL SGA 60 cordless sprayer may provide a more economical alternative within the STIHL AK System.
