Buying Guide for The Best Tow-Behind Sprayer

We often recommend the tow behind weed sprayer for bigger lawns to dispense the weed killer solutions and pesticides as much as possible. Nonetheless, it is not the only thing you must know about a sprayer.

Instead, take the following factors into account.

How to choose the best tow behind sprayer


It is a rule of thumb to start with the necessary components of the sprayer rather than adds-on. The first to mention is the tank material.

The best tow behind lawn sprayer must feature a tank resistant to corrosion. Thus, you should never opt-in materials such as aluminum, galvanized, and steel. They possibly react to weed killer, fertilizer herbicide, pesticide and herbicides. Rather than that, choose polyethylene, fiberglass, and stainless-steel ones.

  • A poly tank is often affordable and lightweight. However, resistance is just moderate. They are also possibly damaged by direct heat.
  • Fiberglass is ultra-light, meaning you can work with the tank effortlessly. Even more, this material is rust-proof. The problem is, you must maintain a temperature within 32˚F and below; otherwise, the liquid inside might explode.
  • Of the three, stainless steel comes with a balance of resistance and maintenance. In other words, you can expose it outside frequently. The cost of stainless-steel tanks is also affordable. Almost all are good, except for the weight. Mounting it around is such a task, let alone move it around your vegetable garden.

Tank Sizes

Tank sizes are based on your purpose that you can go for a small or big sprayer. Normally, a compact tool is useful for price and weight.

An average-sized tool of 13 to 15 gallons is enough for a little garden and backyard. For a bigger one, just get a tank of 20 to 25 gallons. Notably, a pull behind sprayer 100 gallon tank is available for industrial purposes.

Pressure gauge

It is undeniable that high-pressure means more quick and effective spraying. Meanwhile, it eats up the tank and energy more quickly. Nonetheless, the low pressure is no good. The liquid is too weak to reach the lawn areas and even might be blown by the wind.

So, what is the right pressure? – From our experience, a sprayer with 70 PSI and above is powerful enough.

Also, take a look at the output flow rate. It indicates the amount of liquid sprayed at a time. The lowest acceptable output is 2 gallons or a bit less. Whereas, heavy-duty towable sprayers can spray 7 gallons out.

Speaking of the pressure gauges, you should also choose one which allows adjusting the gauge to your physical force.


Since the spray is then attached to and pulled by your vehicle, you need to check on the wheels, to be specific, the tank sizes and materials.

Recommended wheels are made of pneumatic tires so that they can support the completely-loaded tank and help you move around comfortably.

For smooth areas like the backyard, you had better buy small wheels. In contrast, to travel on bushes and rocks in the garden, giant wheels of 12 inches are more useful.

Adjustable nozzles

The nozzles are directly connected to the pressure system. Thus, these parts are vital. There are several types of nozzles to consider.

  • Conventional nozzles: They only work with the PSI of 40 and above. Otherwise, the spray pattern possibly collapses.
  • Pre-orifice nozzles: At 40 PSI, the spray is less drift, but you will have to elevate the pressure several times to protect the pattern.
  • Lo-pres air induced nozzles: These patterns work well on 50 to 60 PSI. The drift is not prone, and the nozzles cover a functional area.
  • High-pres air induced nozzles: The sprayers with such nozzles are ideal for PSI of 60 to 80. At higher pressure, the drift might happen.

Additional booms

Most top-rated tow behind sprayering tools feature booms to improve the coverage. You can choose between three types of booms according to your requirements.

  • Dry booms – most commonly used: The nozzles hung above the sprayer’s turf is supported by these booms to provide a more powerful coverage.
  • Wet booms: They are hollow enough to carry on the liquid to the tips. As a result, the sprayer can cover lots of paths. What’s more, the wet booms are adjustable to different directions.
  • Dripless booms: Coming in a compact design, the tow dripless sprayer booms make it easy to move and store the prayer. Besides, the coverage capacity is excellent, as well.

Other features to look

  • Tow behind sprayer can run on an electrical system or a battery. If it is the latter case, battery clips are included to connect your sprayer with the vehicle battery.
  • Besides fundamental factors as above, you can also consider buying hand wands to spot spray. The hand wands help reach a small piece of land if needed.
  • Foldable arms of boom and removable wheels are preferred by those not having space for easy storage.
  • A remote switch is, for sure, convenient to manage the sprayer when you need to stop it.


Is a tow behind sprayer and pull behind sprayer the same?

Yes, the two are the same. So when we mention the pull-behind sprayer, we mean it a tow-behind sprayer as well.

How does a tow behind sprayer work?

The professional tow sprayer includes a tank, a pump, along with delivery systems. However, to work on itself rather than you have to contact with the hose, the tank is often extraordinary weight and needs supporting by saddles or cradles.

Plus, the tow-behind sprayer features a skid mount with two runners to hold the engine and the pump to the truck’s back or truck. Even more, it is possible to convert the skid to a trailer with the support of a universal hitch and an axle.

On running, the air flows are pushed in at a high velocity. Then, the low pressure above the tube helps give off the liquid quickly.

What is the principle of a pull behind sprayer with boom?

When you need to cover broad areas quickly, we recommend equipping your tow-behind spray with a full perpendicular tube having various spray nozzles. Such a part is called a boom.

The boom is useful to adjust the spray widths as your wish.

How to maintain your tow behind sprayer?

To ensure that the sprayer can work effectively over time, you must maintain it the right way. Here we share some maintenance tips:

  • Inspect for leaks in loose fittings and hose cracks before filling up the tank.
  • Wash the strainers and tips regularly. Remember to soak the clogs in soapy water and with a toothpick, if necessary.
  • Follow the pressure limits recommended by the manufacturer and type of sprayers. Usually, 30 PSI is ideal for herbicide and pesticide, and the less PSI is for fungicides and insecticides.
  • Open the spray and check on the flow rate of the discharge spray pattern.
  • Guarantee to tighten the hose properly before adjusting the valve to your exact needs. Release the pressure system when not in use.
  • Do not always use the full capacity. Let your spray take a break sometimes.
