But as well as precision spraying, it’s also good for wide coverage. Easily spraying a 10 ft. swath as you maneuver over fields, roadways, or lawns.

Buyer’s Guide: Choosing A Tow Behind Sprayer

tow sprayer

There are many different tow behind sprayers available on the market. They come in varying sizes, and with different capabilities and features.

How do you choose the best tow behind sprayer?

Let’s take a look at some of the main things to consider before you buy.

Tank Material

When spraying chemicals such as weed killer and insecticide it’s important that the tank is made from material that won’t easily corrode.

The majority of tanks are made from thick polyethylene plastic as it’s light, durable, and easy to manufacture. But you can also get tanks made from steel or fiberglass.

High-quality polyethylene tanks will come with UV protection to prevent them being damaged by regular sun exposure.

Fiberglass is very durable. And it shares some benefits with polyethylene as it’s light and rustproof.

Stainless steel is the most durable material, being highly resistant to impact and corrosion. And it gives you many years of use when the tank is made well. But it’s very heavy and significantly more expensive.

Tank Capacity

The size of the area you need to spray will determine the appropriate tank capacity for you.

The best tow behind sprayers for homeowners have tank sizes that range from around 13-gallons at the smaller end of the market to 25-gallons on the bigger units. Commercial tow behind sprayers are also available with up to 100-gallon capacity.

Most people with a small or medium-sized area to spray of about 1-1.5 acres or less will get by with a tank size somewhere around 15-20 gallons.

You don’t want the hassle of having to stop to refill it partway through working, so getting one that’s large enough to do the job will make life a lot easier.

It’s also worth remembering that smaller units are often less expensive. So you’ll get better value for money by getting one that suits your needs.

GPM Output

The fluid output through a spray nozzle can be measured in gallons-per-minute (GPM).

At higher gallons per minute, the tank will empty faster. But this will allow you to complete the job quicker.

At a lower gallon per minute you might have to drive more slowly to ensure adequate coverage of the treated area.

The Pressure

The pressure that the fluid in your tank is pumped at is measured in PSI (pounds per square inch). The greater the PSI the stronger the sprayed stream and the greater distance of coverage you can often expect to get.

Spray Width

The spray width will give you a good idea of the area you will spray with each pass. The best tow behind sprayer for bigger properties will have a wider spray width so you can complete your job a lot quicker. But may be unnecessary for a small yard.

Many tow sprayers come with adjustable nozzles so you can increase or decrease the spray width to suit your requirements.

Sprayer Boom

The sprayer boom also plays a part in getting good coverage of your yard when spraying.

Its main function is to help spray the liquid in the tank over a wider area as you drive up and down.

Different types are available:

Dry booms provide a frame for the hoses that carry fluid from the tank. This is then sprayed through nozzles that are positioned along it. One big advantage of dry booms is that they usually cost less than other options.

In a wet boom, the pipe system not only acts as support, but also delivers the fluid to the spray nozzles as well. Some of the advantages of wet booms are that they have less chance of becoming blocked and contaminated with residues, and are easier to flush out.

Dripless booms have no-drip diaphragm check valve nozzles and do as the name suggests.

Spray Nozzles

Different types of spray nozzles produce different spray patterns. They can be used to give you the correct coverage depending on the job you’re doing.

Take a look at the instructions on the chemical you’re spraying. It will usually tell you the type of nozzle to use to get the best results.

Here are some of the common types of agricultural spray nozzles along with the chemicals that are well suited to their use:

Hollow cone nozzles work well well for spraying fungicides when you have pressure from 40-100 PSI. The smaller droplets sprayed give you good coverage and penetration.

Most insecticides also work well with hollow cone nozzles.

Many herbicides, such as glyphosate, work best when sprayed in small droplets as well. In this case, a good choice would be a flat fan nozzle.

However, when using Dicamba it’s a good idea to use a flood nozzle for larger drops.

Tires

If you know you’ll always be towing your sprayer over a smooth flat lawn then this isn’t as big a consideration.

But if you’ll be maneuvering it over difficult, uneven, and muddy terrain then the type of wheels it has are important to consider.

Larger wheels will make the job easier than smaller ones. And look for the best tow behind sprayers with a good tread to provide grip.

Pneumatic tires are popular and provide excellent stability. But if you think there’s a chance of puncture it might be better to get no-flat tires instead.

Hitch

The hitch is used for connecting your pull behind sprayer to the back of your lawn tractor, lawn mower, or ATV. Most models come with a universal hitch to make connection easy.

Additional Features

The best tow behind sprayers come with added features that make spraying and storing easier. Here are some of the things you’ll find:.

A hand wand is required for accurate spot spraying. With a long hose, you can do this while driving. Or you can stop and walk the length of the hose to a better location.

A remote switch gives you added convenience. You can turn the sprayer on and off without leaving the seat of your vehicle.

If you don’t have a lot of storage space then features like foldable boom arms, foldable tongues, and removable wheels and axles can make the unit more compact and easy to find space for.

The best pull behind sprayers often come with battery clips to help you connect to the battery on your vehicle.

Conclusion

So, what is the best tow behind sprayer?
