Stihl SG 71
Best OverallPros
- Brass pump resists corrosion
- Large capacity for medium gardens
- Comfortable carrying strap
Cons
- No pressure gauge
- Heavier than plastic models
The Stihl SG 71 is the standard bearer for manual sprayers. Its 7.5-litre tank is ideal for medium-sized gardens, and the brass pump cylinder is far more durable than the plastic alternatives found on cheaper units. Owner reviews consistently praise its ability to maintain pressure without leaking, even after several seasons of use.
The spray lance delivers a consistent jet pattern, and the shut-off valve is ergonomic. While it lacks a pressure gauge, the pump action is smooth enough to feel when you have reached optimal pressure. For anyone wanting a no-fuss, long-lasting manual sprayer, the SG 71 is the clear choice.
Stihl SGA 85
Best Battery BackpackPros
- No manual pumping required
- Large 12L tank for big jobs
- Adjustable pressure settings
Cons
- Requires AK battery and charger
- Heavier than manual models
The Stihl SGA 85 is the most convenient sprayer for large properties. It runs on Stihl's AK battery platform, meaning the same battery fits your trimmer or blower. The electric pump delivers up to 3 bar of pressure, which is more than enough for weed control and fertilising, and it maintains that pressure consistently without drops.
The backpack design distributes the 12-litre load comfortably, and the wand has an adjustable nozzle from jet to cone. Owners note that runtime on a single AK 30 battery is sufficient for a full tank of spray. The only downside is the upfront cost if you do not already own Stihl AK batteries.
Stihl SG 51
Best for Small GardensPros
- Lightweight and easy to carry
- Brass pump for durability
- Good for spot treatment
Cons
- 5L tank may need refilling
- No shoulder strap included
The Stihl SG 51 is essentially a smaller version of the SG 71, making it perfect for smaller gardens or precise spot treatments. It retains the same brass pump mechanism, which is the key to its longevity. Users report that it pressurises quickly and holds pressure well for a full spray session.
At 1.8 kg empty, it is noticeably lighter than the 7.5-litre models. The tank is translucent, allowing you to see the liquid level easily. The main limitation is the 5-litre capacity, which means more frequent refills for larger areas, but for a typical town garden, it is ideal.
Stihl SG 31
Best Budget ManualPros
- Very affordable
- Extremely lightweight
- Good for small tasks
Cons
- Plastic pump less durable
- Small tank capacity
The Stihl SG 31 is the entry-level sprayer in the Stihl range. It is designed for light, occasional use such as spraying houseplants or a very small patio. The plastic pump cylinder is adequate for this purpose, though it will not last as long as the brass pumps on higher-end models.
The 3.5-litre tank is small, but that keeps the unit very light at just 1.2 kg. The spray pattern is acceptable for the price, and the shut-off valve works reliably. For a budget-friendly Stihl option that still carries the brand's build quality, the SG 31 is a solid choice.
Stihl SGA 45
Best Battery HandheldPros
- Battery powered, no pumping
- Compact and portable
- Quiet operation
Cons
- Smaller tank than backpack
- Battery and charger sold separately
The Stihl SGA 45 is the handheld battery-powered option for those who want the convenience of electric spraying without the weight of a backpack. It uses the same AK battery system as the SGA 85, so batteries are interchangeable. The 4.5-litre tank is suitable for medium-sized gardens or for carrying around for spot treatments.
The pressure is regulated electronically, providing a consistent spray without the need for manual pumping. The wand has a brass nozzle with adjustable spray patterns. Owner reviews highlight the ease of use and the fact that it is much quieter than petrol alternatives. The main drawback is that the battery and charger are not included, adding to the initial cost.
What to check before buying a Stihl garden sprayer
First, consider the tank capacity. A 3.5-litre model like the SG 31 is fine for small patios, while a 12-litre backpack like the SGA 85 is better for large gardens. Second, decide between manual and battery. Manual sprayers are cheaper and lighter, but battery models offer consistent pressure without pumping. Third, check the pump material. Brass pumps are much more durable than plastic ones and are worth the extra cost for regular use. Finally, if you choose a battery model, factor in the cost of the Stihl AK battery and charger if you do not already own them.
Mistakes to avoid
Do not buy a small tank if you have a large garden. Refilling constantly is frustrating and wastes time. Avoid plastic pump models if you plan to spray frequently, as they wear out faster. Do not assume all Stihl sprayers come with a battery. The SGA models require a separate purchase. Finally, do not neglect to clean the sprayer after each use, especially with herbicides, as residue can clog the nozzle and damage seals.
