The STIHL SG 31 is a 5-litre manual pressure sprayer designed for occasional spraying work in larger gardens, allotments, borders and cultivated areas. Its generous container, large filler opening and telescopic spray tube make it a practical choice for applying compatible plant treatments, liquid fertilisers, pest-control products and weed treatments.
Unlike a backpack sprayer, the SG 31 is a portable manual model that can be carried using its shoulder strap and pressurised using the integrated pump. It is ideal for gardeners who need more capacity and reach than a small hand sprayer but do not require the size of a 12 or 18-litre backpack machine.

Key features of the STIHL SG 31
- Five-litre container: Provides useful capacity for treating larger borders, vegetable plots, allotments and garden areas without making the sprayer unnecessarily bulky.
- Large filler opening: Makes the container easier to fill, empty and clean after use.
- Ergonomic shut-off valve: The large operating lever makes it easy to start and stop spraying while maintaining control of the spray lance.
- Telescopic spray tube: The working length can be adjusted from approximately 520mm to 900mm, helping you reach plants, beds and awkward areas more comfortably.
- Long connecting hose: The 1,300mm hose gives you useful freedom of movement while working.
- Hollow-cone nozzle included: Designed for accurate application around individual plants and targeted areas.
- Fan-jet nozzle included: Produces a broader spray pattern for treating wider strips and surface areas.
- PKA 30 compatible: The manual pump can be replaced with the compatible STIHL PKA 30 cordless pump head, allowing the sprayer to maintain pressure without repeated manual pumping.
What can the STIHL SG 31 be used for?
The SG 31 is suitable for a wide range of occasional garden spraying jobs, provided the liquid being applied is approved for use in a pressure sprayer. Typical applications include:
- Applying compatible liquid plant feeds and fertilisers
- Treating garden borders, beds and vegetable plots
- Applying approved pest and plant-protection treatments
- Targeted weed control on paths, borders and cultivated areas
- Spraying individual plants using the hollow-cone nozzle
- Covering wider strips using the supplied fan-jet nozzle
Masseys stocks a wide range of plant food and liquid fertilisers, plant pest-control products and garden weedkillers. Always check the treatment label before placing any product in the sprayer.
Why Masseys recommends the STIHL SG 31
At Masseys, we recommend the STIHL SG 31 to customers who want a dependable garden sprayer with more capacity, control and reach than a basic hand-held model, but who do not need to carry a large backpack sprayer.
The five-litre size is a sensible balance for regular domestic garden work. It holds enough liquid for meaningful spraying jobs while remaining more manageable than a fully loaded 12 or 18-litre machine. The large filler opening also makes an important practical difference when mixing, filling and cleaning the sprayer.
We particularly like the fact that STIHL includes both a hollow-cone nozzle and a fan-jet nozzle as standard. This gives the SG 31 genuine versatility: one nozzle can be used for accurate treatment around individual plants, while the other covers broader areas more efficiently.
Masseys is an authorised STIHL dealer based in Woodville, Swadlincote. Our team can help you choose between the SG 31 and the larger models in the STIHL range.

Should I choose the SG 31, SG 51 or SG 71?
The right model depends principally on the size of the area being treated and how long you expect to work between refills.
- Choose the STIHL SG 31 for occasional domestic work where a manageable five-litre manual sprayer provides sufficient capacity.
- Choose the STIHL SG 51 backpack sprayer when you need a larger 12-litre container for extended work and would prefer to carry the liquid on your back.
- Choose the STIHL SG 71 backpack sprayer for more demanding or professional work requiring an 18-litre container.
- Consider the STIHL SGA 30 cordless sprayer when you want battery-powered pressure rather than regular manual pumping.
Using your STIHL SG 31 safely
Always read the STIHL instruction manual and the instructions supplied with the product being applied. Check that the liquid is suitable for use in a pressure sprayer and follow the specified dilution rate, application conditions and personal-protection requirements.
Do not leave mixed treatments inside the container after use. Release the pressure safely, empty the sprayer in accordance with the product instructions and rinse the container, hose, lance and nozzle thoroughly. Using separate sprayers for weedkiller and plant feeds can also reduce the risk of accidental cross-contamination.
Frequently asked questions
