How Can a Pull Behind Garden Sprayer Help You?

If you have a large property with extensive landscaping, all of your grasses and plants need to be protected from weather, weeds and insects. A sprayer can simplify the task of watering and applying pesticides or weed killers. You simply attach the tow sprayer to your sit-down mower or four-wheeler and take care of your plants with ease. They come in a variety of sizes, from small sprayers to big workhorse pull behind sprayers.

What to Look for in a Tow Behind Sprayer

Boom vs Boomless Sprayer

The first thing you want to consider is whether you want a boom sprayer or boomless sprayer. They are meant for different kinds of spraying. A boomless sprayer is far better suited for uneven terrain, orchards, or for around objects in the yard. The best boom sprayers are more suited for field spraying. Using a yard sprayer with boom does give you more even coverage and it is better in windy conditions, but boomless spraying works for more diversified terrain and plants.

When it comes to buying a towable weed sprayer, there are a few things you need to consider. Below, we cover these components:

The Tank

There are two things to be concerned about with the tank. What is it made from and how much liquid it can hold?

Tank Capacity: The capacity of the tank can range from a smaller 13 gallon tank to a 200 gallon tank. For most residential properties, you will be fine with a 15 gallon tank. Larger tanks, like 100 gallon pull behind sprayers, are meant for commercial or industrial use.

Tank Material: When it comes to the material of your tank, what it is made from is extremely important. If you plan to use your sprayer for pesticides or any type of weed killer then you need materials that won?t react with the chemicals in the solution. Most tanks are made from polyethylene, fiberglass or stainless steel. Polyethylene is the most common as it is cheaper to manufacture, but if left out in direct sunlight it can be damaged. Fiberglass is more durable than polyethylene, is lightweight and it won?t rust, but it does not tolerate cold. Stainless steel is the best option as far as durability, but it will be heavier and more expensive.


The pressure of your sprayer is measured in PSI (pounds per square inch). The pressure indicates how well your sprayer is working. If you do not have enough pressure, you will not get the water or pesticides to go where you need them to go. You want a sprayer with a 70 PSI or higher to get adequate coverage.

Spray Width

The spray width is the amount of area you are covering as you spray. The wider the spray width, the faster you can spray your property. Most come with adjustable nozzles so you can narrow or widen the spray width.

Different Types of Spray Nozzles

There are several different types of lawn sprayer boom nozzles on the market and you want the right style to ensure you get adequate coverage when you?re spraying. Below, you will find the different types of agricultural spray nozzles and the chemicals they work best with. The chemical that you are using will tell you the nozzle that works best with their product, but here is a general guide.

Best spray nozzles for fungicides: For fungicides, you want a hollow cone nozzle with the pressure between 40?100 PSI. The size of the droplets will be smaller, but you get better penetration.

Best spray nozzles for glyphosate: Glyphosate works best when it is sprayed in smaller droplet sizes, and for that you should use a flat fan nozzle.

Best spray nozzles for insecticides: Check first with the manufacturer of your insecticide to see what nozzle they recommend for best coverage, but most insecticides will use a hollow cone nozzle.

Best spray nozzles for herbicides: To spray herbicides you can use the regular flat fan nozzle to give you complete coverage.

Best spray nozzles for Dicamba: When spraying Dicamba, you want to have a nozzle that will give you larger droplets. As recommended by the manufacturer, flood type nozzles work best.


The hitch is how you connect your ATV tow behind sprayer. Most units have a universal hitch that will work with any lawn tractor sprayer, but double check to make sure.


You won?t be towing your sprayer over smooth paved road, but rather over a variety of terrain. Thus, you will need good tires. Pneumatic tires will give you better stability and they are easier to tow, but they are more likely to puncture, so you might want to look into no-flat tires.

How to Calibrate a Sprayer that has Booms

If you want to get the most coverage from your tow-behind trailer boom broadcast and spot sprayer, then you need to make sure that it is calibrated correctly. Here are the steps that you need to take to calibrate your sprayer.

1. Fill your sprayer half full with just water and run it for a few minutes to make sure there are no leaks and everything is working properly.

2. Measure the distance in inches between the nozzles. That will help you calculate the travel distance on your property. The appropriate distances for different nozzle spacing is as follows: 408 ft for a 10-inch spacing, 272 ft for a 15-inch spacing, 204 ft for 20-inch spacing, 136 feet for a 30-inch spacing, and 102 feet for a 40-inch spacing.

3. Drive around your property at the same speed that you would to spray and measure how long it takes. You may want to do this more than once and take the average time.

4. Leave your sprayer parked, but run the sprayer for the same amount of time it took you to drive around your property. Catch the liquid from each nozzle in a jar.

5. Find out the average output of your nozzles. That output in ounces will be equal to application rate in gallons per acre.

6. Compare the rate you got in step 5 against the application rate recommended by the herbicide/pesticide manufacturer. If you?re within 5%, then you are fine. If is too high, then decrease the spray pressure. If it is too low, then increase the spray pressure. You need to be mindful to stay within the safety conditions of the sprayer.

Keep testing and adjusting until you are within 5% of the application rate.
