Sprayer "Shtil" is intended for the following gardening works:

• processing of trees and shrubs in order to destroy dangerous pests;
• preventive treatment of crops from fungus and powdery mildew;
• watering with a uniform distribution of liquid over the surface of the plant;
• application of liquid fertilizers to the soil.

The technique of this brand is often used for spraying vineyards.

Sprayer "Calm"

The sprayer is very simple: a liquid for processing plants or liquid fertilizing is poured into a plastic or metal tank equipped with a measuring scale. When the power is turned on (for electric, gasoline, battery versions) or mechanical pressure is applied to the lever (manual version), the compressor starts working.

An increased pressure is created in the reservoir, and the liquid begins to flow from it into the atomizer, from which it enters the air in the form of a powerful stream, a weak jet or the smallest particles resembling fog (depending on the pressure that can be adjusted).

Care and storage of sprayers Stihl

In order for the device to work for a long time and without breakdowns, it must be properly looked after and the manufacturer's recommendations must be followed:

Range of prices for gasoline sprayers and subtleties of choice

The cost of the described garden equipment is formed depending on the characteristics of power and performance, as well as belonging to a particular brand.

So a backpack gasoline sprayer Champion PS-257 costs about 9,000 rubles.

But when purchasing equipment of this kind, you need to remember that in the event of a malfunction, it will be extremely difficult to get the original part.

On the territory of Russia, the activity of technical centers for the maintenance of this type is not practiced. techniques from Chinese manufacturers.

For devices that are more serious in terms of technical parameters (power from 3 hp and more, the ability to process up to 5 hectares of green spaces in one working day) from manufacturers such as Echo, Solo, Oleo-Mac, Efco, Sthil are fixed prices from 20 000 to 50,000 rubles.

For consumers who prefer to rent them to the purchase of sprayers, the rental of an apparatus of this category will cost from 2,500 rubles per day.

Before you buy a gas powered knapsack sprayer, you need to assess the processing area.

If the area is less than 1 hectare, buying this particular type of motor sprayer will be irrational.

Designed specifically for large scale green spaces, these devices are preferable to use when working on garden areas and plantations over 1 hectare.

When choosing a specific model, a practical owner will definitely try on the device for himself, checking the convenience and correspondence of the mass of the unit to his individual indicators of growth and strength.

Also, directly in the store, you can request a control check for the normal functioning of the sprayer, checking the air flow and the tightness of the assembly.

Having opted for a brand that is well-deserved by consumers around the world, the consumer acquires not only reliable and trouble-free equipment, but also provides himself with a guarantee that the device will serve him for many years.

This is really possible with regular and competent maintenance.

We offer you to watch a video example of how it is necessary to treat a site from pests using a backpack gasoline sprayer:

Advantages and disadvantages of Stihl sprayers

Gardening equipment "Shtil" has long been known to Russian gardeners and gardeners. This brand is really trusted. The Shtil brand garden sprayer has many advantages over other industrial spray gun options. Among the obvious advantages, the following should be noted:

• good quality metal and plastic used for the manufacture of the device;
• a large number of additional accessories included in the kit;
• fast and high-quality distribution of liquid, its deep penetration into the soil;
• the possibility of high-quality irrigation under strong pressure without erosion of the root system.

However, this device also has disadvantages. Gardeners who often use this brand of sprayers say:

• If the device breaks down, it is quite difficult to find spare parts for it and fix the sprayer at home with your own hands.
• For spray guns with a plastic reservoir, the tank fails quite quickly.
• When using hand sprayers, it is sometimes necessary to press the lever with force to increase the pressure, which can subsequently lead to the failure of the lever.
• The liquid that is poured into the tank must have a temperature of up to 30 degrees. In this regard, the Shtil sprayer is not suitable for applying fertilizers that must be diluted in hot water.

Important! Unlike other brands (for example, from the well-known Beetle), the Shtil sprayer has special seals made of especially durable material, so it can be used to spray aggressive chemicals, including powerful poisons to destroy the Colorado potato beetle

Design features and principle of operation

In order to clearly understand the main features of knapsack sprayers, you should familiarize yourself with the types of devices offered by manufacturers, namely, with pumping and sprayer options.

First, let's take a look at the pumping models. This is the only type of spray that does not have a chemical fluid reservoir. The treatment composition is drawn in by the pump structure piston inside the device, and after a simple push on the handle, it is pushed out.

Sprayer models have a separate fluid reservoir. It is presented in the form of a plastic bottle with a neck. The process of uniform distribution of the chemical composition occurs when you press the design button or the handle with a pump pump, which is neatly hidden in the product lid.

The range of nozzles also differs in the way of transfer.

Professional products are more large in size and carried by means of a wheeled system.

As for the knapsack sprayers directly, it should be noted that their design features are designed specifically for ease of use at home. The rectangular shape of the device is equipped with two sturdy shoulder straps that connect to each other on the stomach. Such fastening firmly fixes the unit behind the back and prevents even minimal displacement during operation.

The pump chamber, which builds up pressure, is located at the bottom of the structure, so that the chemical liquid does not spill onto a person in cases of possible depressurization. Even the pump chamber itself will not crack or burst.

Model Calm SR 430

The multifunctional sprayer Stihl SR 430 will be indispensable for work in the garden and on the personal plot.The innovative design used to create the engine made it powerful and economical. During operation, the Stihl sprayer does not vibrate on the back of the user, thanks to a specially implemented system. The machine can be operated even with one hand without any additional effort.

The standard model has the following characteristics:

• The Stihl petrol sprayer is equipped with a 1 liter fuel tank, while its maximum productivity is 1300 m3 / h.
• The radius of action reaches 14.5 meters horizontally.
• The mix tank has a capacity of 14 liters, and the large opening makes it quick and easy to fill.
• Three grids are provided to select the optimal flow type.

Types of sprayers Stihl

There are the following types of sprayers produced under the Shtil brand:

• gasoline;
• knapsack;
• electrical;
• rechargeable.

The gasoline sprayer "Calm" is easy to use, but it is quite expensive and often breaks down. He also consumes a lot of gasoline.

The electric model is more economical than the Stihl petrol sprayer, as it does not require liquid fuel and does not consume much electricity. However, the electric model is inconvenient because it is "tied" to a wire. Therefore, if the plot is large and it is necessary to process plants at different ends of the garden, the electric unit will be inconvenient to use. Better to purchase a rechargeable version. It is compact and can be easily carried from place to place.

Note! Spare batteries are included with some models. This is very convenient as the batteries drain quickly when the device is running at full capacity.

The Stihl knapsack sprayer sprays liquid due to mechanical action on the pump lever, which is why it is also called manual. Most models are equipped with shut-off and safety valves. Most often in stores you can find sprayers with a reservoir designed for 12 liters.

How to use?

Despite the design features of each sprayer, the principle of operation is the same for them. First you need to assemble the device. Gardeners rinse the container and sprayer tube after each chemical treatment. In principle, these are the main parts that need to be connected together for subsequent work. A chemical composition is poured into the container for treatment against pests.

In the manual version, the lever is inflated, and in the electric and gasoline versions, this process occurs automatically. The solution from the main body flows through the hose and enters the boom. Air is injected, from which pressure is created and atomization begins.

Which garden sprayer is the best to use

In order not to waste your money, it is important to figure out which garden sprayer is best for use in certain situations. To do this, consider the types of these devices and the capabilities of each type.

Manual pump sprayers

These sprayers got their name due to the presence of a built-in pump, which builds up pressure with the help of effort from the operator. A lever or vertical handle for inflation is provided on the body. Sprayers of this category are divided by the capacity of the liquid reservoir and are available for home and summer cottages (with a volume of 3-5 liters) and a large vegetable garden of 10 acres (containing 10-12 liters).

The former are worn on the shoulder with a single strap. The latter are equipped with a knapsack mount.

Manual knapsack sprayer.

At the outlet of the container, a mesh is built in to trap debris. Next, the solution enters the flexible channel and the rod, which is held by the operator. At the end of the boom there is a spray that converts the flow into a fine spray. Changing nozzles allows the spray pattern to be modified according to the height and frequency of planting in the greenhouse or garden bed.

Usually the pressure inside does not exceed 3 atm, but in rare cases it is 4 atm. To control the indicator, a pressure gauge and a safety valve are provided. The inconvenience is that periodically you will have to stop the process and pump the pressure with the handle. But hand-held gardening machines are simpler in device and cheaper to repair.

Cordless sprayers

Instead of manually pressurizing it, it uses an electric motor powered by a battery. The operator uses less effort when working and can cover a large area in the same amount of time compared to manual pump sprayers. The battery will work from 4 to 6 hours, depending on the capacity of the battery. It is 8-10 A / h.

Batteries with "memory" effect will have to be fully discharged in order to be charged later. Models with Li-ion batteries can be recharged every time before going out into the garden, and then the energy supply will be enough for the planned amount of work. The capacity of tanks in such sprayers is 10-16 liters. This is environmentally friendly equipment that does not emit harmful gases and operates relatively quietly, but its repair is more expensive.

After discharging the battery, you will have to take a break from work or install a replaceable battery. It is worth making a choice in favor of these devices if you want to save energy during operation, for example, in the case of the elderly or the need to process large areas.

Motor sprayers

The third category of sprayers is powered by gasoline 2-stroke engines. Here, the performance in terms of spraying range depends on the power of the internal combustion engine. It ranges from 0.8 to 4 hp. The capacity of the solution tanks is 7-17 liters. Models in this category are practical for processing large orchards with fruit trees, vegetable gardens of 40-50 acres. But in greenhouses it will no longer be possible to use the device, due to the release of carbon monoxide from the exhaust system.

Although the operator does not need to manually pump the pressure, the models weigh 20 kg and are not easy to carry on the shoulders. They also hum loudly. But the sprayers will cope with spraying not only 7-15 m in length, but also in height, which is important for trees 2-4 m. Some more models have air injection and can work with powder materials.

Benefits of using motor sprayers

Their choice in favor of sprayers with a gasoline engine is most often made by those consumers for whom the main requirement for this category of equipment is high performance, powerful functionality and coverage of a large area (from 1 hectare) in a relatively short period of time.

It is thanks to the internal combustion engine provided by the design that the models of the considered equipment in terms of the duration of operation, processing speed, spraying range significantly surpass similar analogs of the pump and battery type.

The engine power of gasoline sprayers ranges on average from 1 liter. with. in cheap Chinese models (Patriot PT 415WF-12), up to 5 liters. with. especially advanced samples (Oleo-Mac MB 80).

The volume of the tank for the composition is in the range from 12 to 30 liters, which allows the processing of territories of medium and large areas without additional refueling.

In addition, the units of this category provide for the spraying of not only liquid, but also granular and powdery substances.

This greatly expands the field of application of the devices, adding the possibility of sowing seeds or spraying fertilizers in a dry form.

Unlike pump and battery sprayers, the composition is supplied not through a “fishing rod” tube, but through a wide distribution pipe with the function of regulating the speed and intensity of the sprayed flow.

Completion with additional extension equipment makes it possible to use this type of apparatus at high heights.

The modern market for this technology is represented by a wide range of models designed for any level of required performance and costs.

Among the world-famous manufacturers of gasoline knapsack sprayers that have proven themselves from the best side are Gardena, Sthil, Solo (Germany), Efco, Oleo-Mac (Italy), Echo (Japan).

Brands whose models are consistently popular among the widest consumer audience due to more affordable prices: Sadko (Czech Republic), Champion, Green Field, Patriot, Zirka (China).

Undoubtedly, the purchase of a device from a trusted well-known company pours into a decent amount, however, it eliminates further problems due to the availability of service centers and a full set of required spare parts and consumables.

Types of garden sprayers

As for the volume of the product's reservoir, it must correspond to the liquid consumption for the number of plants on the site:

• 1 - 2 liter hand sprayers are required for 10 m2 of plantings;

• Small nozzles from 2 - 3 liters are used for small greenhouses with a minimum number of plants and for 1 young tree;

• Medium to large nozzles from 10 liters are suitable for several mature trees.

Thus, if you plan to treat a small flower garden, flower bed or mini-greenhouse, then the simplest manual model, like the Comfort sprayer, 3 l Gardena, is sufficient. It is an ideal tool for applying protection and fertilization, as well as for targeted soft irrigation, such as seedlings. Ideally, the sprayer body is made of transparent plastic to control the liquid level. In addition to the different capacity of the tanks, garden equipment is divided into several types depending on the mechanism: manual, pump type, pump (or pneumatic), battery and fuel.

1. Hand sprayers of sprayer type are the cheapest and simplest units with a tank volume of up to 3 - 5 liters. They are bought for processing fruits, seedlings and vegetables in greenhouses, as well as for small flower beds. For large areas, they are useless because they have a small volume and poor spraying range. Spraying is done by pressing a lever, while the mixer is located directly in the head of the product. After the chemicals are diluted, the hose of the unit is lowered into the tank and a nozzle is twisted on the neck. That's it, the sprayer is ready to go.

2. Pump sprayers do not have a separate container and outwardly resemble ordinary bicycle pumps, only they do not pump air, but liquid with impurities. The sprayed liquid in such products, after dropping into the container, is sucked in by the pump piston, after which it is sprayed out through a special nozzle.

3. Pump sprayers have a pneumatic pump in their design. Its principle of operation is quite simple: it pumps air into the tank, the pressure increases and the solution is pushed onto the plant leaves through a spray bottle. When the pressure drops, pumping is repeated again. There are two types of pump units: manual with a volume of up to 2 liters and a shoulder knapsack with a volume of 3 liters or more. Since it is already inconvenient to hold such a weight in hands, manufacturers supply models with straps to carry them on the shoulder, like a bag. Another feature of the shoulder product is the presence of a hose with a nozzle. The most comfortable ones are telescopic with the ability to extend up to 3 meters, this will allow you to reach even tall trees. Shoulder pump pumps from 12 liters are worn on the back like a knapsack. Air in such models is pumped in by pressing the handle on the side of the case. This design is convenient in that it does not interrupt the operation of the unit in order to pump air. With the help of knapsack pump equipment, you can process up to 30-50 acres per day.

4. Cordless sprayers differ from manual and pump-driven counterparts in that the pressure is generated automatically. The rechargeable battery in the case does it for you.Charging the device lasts for several hours, during which the user sprays the solution, directing the hose to the desired plant. Compared to its pump-action sibling, the cordless sprayer creates a stronger spray that easily reaches the tops of tall trees. So if you have several large fruit trees, the rechargeable model will be the perfect purchase.

5. The gasoline unit is the most demanded type of sprayer for summer residents with large areas of up to 1 hectare. The volume of the tank for gasoline models starts from 10 liters, which allows you to process a large area with garden crops at a time. The jet throw range reaches 10-15 meters. The SR 420 Stihl petrol sprayer with a tank capacity of 13 liters and a long range is used for spraying with granular fertilizers, grass seeds, crop protection products and much more. It can also be used as a blower.

In conclusion, we note that before you buy any of several types of sprayers, check its operation right in the store.

Which gasoline sprayer is better

For a small suburban area, experts recommend choosing low-power models. If the unit is bought for a farm, then a device with a four-stroke engine and a spacious fuel tank would be the best option. Ease of use depends on the width of the straps, handle length, weight. Before buying, you need to check the quality of nozzles, filters, rods. If gross flaws or the complete absence of elements in the kit are revealed, it is better to refuse the device. The recommendations of the VyborEksperta project specialists will help you choose a device for processing a personal plot, a garden, taking into account a number of nuances:

• In terms of price / functionality ratio, the Champion PS242 is considered the best option;
• The most inexpensive model - Clever OB-12-N;
• The best gasoline sprayer for high trees - Makita PM7650H;
• User choice - Oleo-Mac MB 80;
• The best price / quality ratio - Stihl SR

When choosing, always consider the number of spare parts, quality of materials, warranty period, maintainability of equipment. If possible, check the ease of use before paying for the item. The analysis of user reviews presented in the rating will allow you to assess in advance all the pros and cons of the selected model.

Right choice

In order to make the right purchase, you need to understand how the technique works.

There are capacitive and tankless sprayers. The first are equipped with a special reservoir, and the latter, respectively, are not. That is, in the second case, the chemicals are diluted in a separate container (bucket), a hose is lowered there and the solution is sprayed without adjusting the pressure and jet. It is very laborious, far from safe and not economical at all. Therefore, opt for a capacitive model.

There are pump sprayers (up to 12 liters), manual (1-7 liters) - the elementary of the existing models. According to many gardeners, the most convenient to use are backpack hydraulic sprayers, the volume of which can reach 20 liters. Their name is derived from the fact that they are worn on the back. Their big plus is the very moderate consumption of chemicals.

There are battery-powered (cordless garden sprayers), electric and motor-powered models. All of them are very easy to use, do not involve much effort during operation.

In most cases, human involvement is minimized.

Remember that the choice of sprayer depends on the size of the area to be treated. In addition to the area, take into account the consumption of liquid for processing: for example, for one bush it will take 1 liter, for an adult tree - up to 10 liters, for a young tree - up to two.
