Keep reading to learn more about each of these backpack sprayers and find the perfect one for you!

What Does a Sprayer Do?

A sprayer is a tool for spraying liquids such as herbicides, pesticides, or fertilizer on a lawn or garden. Sprayer machines come in a range of sizes and capabilities, from tiny spot sprayers to big sprayers with broad grass and plant coverage.

Sprayers differ in size and portability, ranging from easily transportable sprayers (usually backpacks with spray guns) to tow-behind sprayers connected to a tractor that may be up to 60–151 feet long depending on the design of the tractor and your acreage.

Types of Sprayers

There are multiple different models of sprayer available on the market, with the main three types being Tow-behind Sprayers, Handheld Sprayers, and Backpack Sprayers.

Tow-Behind Sprayer

A tow-behind sprayer is a sprayer that connects to the back of a lawn tractor or ATV and you then pull behind it as you work your yard or garden. This enables you to spray herbicides or fertilizer on your plants and grass fast and efficiently.

A tow-behind sprayer has a tank in which the chemicals/fluid are stored, a pump (usually 12 volts) to push the fluid out of the tank, a tow bar, a cart or tires on which the tank rests and a hitch to connect it to the ATV or lawn tractor, and a spray wand for hand spraying.

You may get tow-behind sprayers to attach to an ATV or a tractor model, depending on what you have. Some tow-behind sprayers include lengthy booms that span out in both directions and make for a wide spraying swath. However, these are mostly used by agricultural farmers with acres of arable land and have little-to-no value for most suburban homeowners.

There are also boom-less models, which feature a spraying wand that you hold while driving your mower or tractor to spray the grass or plants you want.

Handheld Sprayer

A handheld sprayer is a sprayer that you carry around with you in your hand because it doesn’t have any pads or shoulder straps to put it on. Because you have to carry them, handheld sprayers are both smaller and lighter than tow-behind and backpack sprayers on average. Their tanks are generally less than 1 gallon in size, and are for both indoor and outdoor use.

Handheld sprayers are less expensive, but they may lack spraying features and aren’t suitable for large open yards. When purchasing a handheld sprayer, keep in mind that holding it for long periods might cause hand and wrist discomfort.

They can either pump the fluids from their tank with a battery or gasoline-powered engine, or they can be pumped by hand using up and down pressure to build up pressure for the sprayer. This may be tiring and time consuming compared to other automatic pump sprayers.

Backpack Sprayer

Backpack sprayers are those who you wear as a backpack while you walk around your lawn spraying plants, vegetation, or your grass.

These sprayers come with larger tanks are more common and are suited to individuals who wish to spray large areas. Backpack sprayers are heavier than handheld models, but the straps that allow you to wear them like a backpack take some of the strain off your hands. Furthermore, since the tank is larger, you can cover a greater area at once.

Backpack sprayers offer a variety of benefits over hand-carried sprayers. They generally come with a wider nozzle selection than hand-carried models, as well as higher pressure and less pumping work. Most manufacturers have also made sure that the weight is evenly dispersed, making it easier to transport for lengthy periods.

Benefits of Using a Backpack Sprayer

Backpack sprayers are easy to use, efficient, and reliable. These handy sprayers are ideal for treating weeds and pests while preserving the natural growth of your plants. Backpack sprayers have adaptable designs and technology, allowing them to be more efficient and convenient to use.

Backpack sprayers are light to carry and don’t require any foreknowledge to operate; anybody with minimal expertise can use it easily. They’re also reusable for many years, and generally do not require much maintenance at all, saving you time and money. If you do need to replace or fix a part, the manufacturer will often send you a replacement, or you can pick one up from your local home and garden store.

Both power options are included with most backpack sprayers. If you go for the manual option, you may use it in your garden, greenhouse, or trees at any time. Battery-powered equipment are more efficient and beneficial in terms of saving time, energy, and labor. They can operate for long periods of time on a single charge.

The higher pressure of the backpack sprayer over a handheld model also allows you cover a larger area in a shorter amount of time and with less effort. The higher pressure also gives you the ability to reach higher places such as the tops of trees or hedges that other manual sprayers can’t reach.

Factors To Keep In Mind Before Buying A Backpack Sprayer

So, when purchasing a backpack sprayer, you must select the one that is appropriate for your lawn’s specific requirements. Here are some factors to consider while purchasing a backpack sprayer.

Tank Design and Durability

Today’s backpack sprayer pumps are often quite light since they feature small tanks made of polyethylene plastic, which is long-lasting and durable, as well as resistant to chemicals as well as UV protected.

They should be of use for at least 5 and up to 10 years. Although the aim was to make them as lightweight as possible, tanks might be heavier if they have a higher capacity.

They are usually available in square, rectangular, and other unusual forms and designs. The tank’s design is quite simple, and most are easy to put together with the equipment that comes with it. Look for one that best complements your lawn and garden work.

Tank Capacity

Sprayers come with anywhere from 1 to 7 gallon tank capacities. The smaller-capacity sprayers you can carry with a handle, and the biggest tow-behind sprayers need to be toted on wheels behind a tractor.

Backpack sprayers are those that fall between the two extremes in terms of size. They’re light enough to carry on your back but too hefty to hold in your hand the whole time.

A 4-gallon backpack sprayer is considered average in size. For routine tasks such as fertilizing a lawn or combating an insect infestation, a 4-gallon tank is sufficient for a yard ranging from 5,000 to 10,000 square feet.

PSI

The term PSI refers to a measure of pressure – pounds per square inch – that can be utilized by backpack sprayers. It’s critical to apply enough pressure in order for your back pack sprayer to function properly. When the pressure is insufficient, an uneven spray will result, which will reduce the efficacy of its contents. When too much pressure is applied to a smaller yard, it can damage plants and property.

The typical PSI for a backpack sprayer is around 70, however smaller versions may operate at as little as 40 PSI and commercial backpacks may attain up to 150 PSI.

A sprayer with a PSI rating of 70 or above is your best option if you have a big yard with numerous hard-to-reach locations or if you are a professional who works in many different-sized lawns and gardens. A moderate pressure between 40 and 70 PSI is sufficient for people with average-sized yards or smaller.

Pumps – Piston vs. Diaphragm

Backpack sprayers are generally equipped with one of two liquid delivery systems – a piston pump or a diaphragm pump.

A piston pump works like the piston of a car engine. It draws liquid from the tank and pushes it out through the outlet valve or nozzle in a repeating cycle. Due to their basic design, easy accessibility for repairs, and beneficial psi ratings, piston pump sprayers are more popular among normal homeowners.

Professionals working in the field of potent pest control and weed killer chemicals require the safe design of a diaphragm pump to protect them from exposure. It’s a sealed system that works by moving liquid back and forth between two sides of a chamber using a diaphragm, ensuring that one side is always full and the other empty.

The diaphragm pump isn’t as strong as the piston pump but it is more resistant to stronger chemicals and so is therefore more safe to use.

Power – Manual vs. Motorized

In backpack sprayers, an internal pump draws liquid out of the chamber, through a hose, and out through a wand and nozzle. This pump can be operated manually or by a motorized system, though this is a more expensive option.

On a manual backpack sprayer, the hand pump is connected to the backpack chamber. Pumping manually for an extended period may lead to muscular tiredness and discomfort, so while this type of sprayer is perfect for small yards, once-per-season tasks, and the average homeowner, it’s less useful for professionals who have to spray for many hours in a day. These types of sprayers can cost between $40 and $150 on average.

Electric backpack sprayers, on the other hand, are powered by either battery or gas, with a battery backpack sprayer being more versatile and simple to use. A motorized sprayer draws liquid from the backpack chamber through the wand without requiring any physical effort on the part of the user.

A motorized sprayer can cost anywhere from $100 to $500, and is usually a better choice for the busy professional who’ll use it frequently because it’s meant for large tasks and long workdays.

Spray Wand

It’s critical to get a high-quality wand of the proper length for your needs. You’ll run into a lot of trouble if you try to do anything with a spray wand that isn’t suitable. One good thing with backpack sprayers is that if the device you buy does not include an appropriate spray wand, you should be able to swap it out.

Spray wands with low quality may leak. Look for one made of high-quality plastic, metal, or stainless steel that can be equipped with adjustable spray nozzles. Some spray handles include a tiny pressure gauge so the user knows the PSI when working.

Nozzle

The nozzles are important components of backpack sprayers. The nozzle regulates the rate of dispersion through the wand. Most versions include an adjustable tip to alter the size and shape of the spray pattern.

The majority of homeowners in most cases will be able to make do with the standard spray nozzle supplied with their machine, though farmers and professional landscapers may wish to purchase a few more high-performance nozzles for their spraying jobs.

Some versions are compatible with professional spray tip attachments for finer targeting and concentrated distribution. The user may switch between spraying functions on the wand, which generates a fan, cone, direct, or wide stream from the nozzle tip by altering or re-positioning the spray nozzle. The nozzle of the sprayer changes its distribution rate, and can vary between 0.3 and 0.5 gallons per minute.

Shoulder Straps and Harnesses

When spraying for lengthy periods, the harness, straps, and padding of a backpack sprayer become essential in terms of user comfort. Landscapers will want a model with adequate padding and lumbar support to make sure they’re comfortable the whole time.

These aid in reducing operator fatigue, allowing you to cover more territory in less time. However, this level of comfort isn’t required for domestic gardeners that only want to spray for a few minutes at a time.

When the tank is full, the harness should feel pleasant and equally distribute the machine’s weight. The sprayer also needs to maintain the same levels of support as the tank empties and gets lighter over time.

Safety

Backpack sprayers are a simple tool that may be used for a variety of purposes, but don’t be fooled by their simplicity. Using a sprayer incorrectly might be hazardous. Blowback and overspray can be quite harmful if you come into direct contact with the liquid spray solution, especially if it has hazardous or strong chemicals.

The failure to follow manufacturers’ instructions might result in the machine being damaged or yourself getting injured.
