Tow-Behind Sprayer Buyer Guide
When it comes to choosing the right pull-behind sprayer, certain characteristics are worth noting. Understanding the key factors in sprayer will help you find the right tool for your yard.
The tank capacity determines how much liquid you can carry in each load. A higher sprayer tank capacity means you don't have to return and refill it to get the job done. Usually, pull behind sprayers have tank capacity anywhere from 15 to 30 gallons.
For small to medium size yards, you can choose a 25-gallon tank capacity. We find it to be a reasonable compromise between performance and ease of use. If you're buying it for farming, you can go for a much larger up to 100-gallon tow behind sprayer.
There are different materials used for storage tank construction. The fiberglass made storage tank is gaining popularity as these are highly durable and lightweight. These are great for areas where the temperature won't go below freezing; otherwise, you risk it cracking.
Polyethylene made tanks are also the right choice due to their high durability and weatherproofing. Most of these tanks have weather protection coating that prevents tanks from cracking or fading.
You should confirm if the tank has these protective coating as these aren't default options. Some manufacturers increase the thickness to withstand weather, but it increases the weight of the tank.
A premium grade tank is made of stainless steel. These are corrosion and weather resistant and are highly durable.
You can use these in any weather conditions without worrying about cracking or damaging the tank. But steel is far heavier than fiberglass or polyethylene made storage tanks and also more expensive.
As a recommendation, for small to medium-sized residential yards, you can safely choose polyethylene tanks. These are sturdy and lightweight while costing less than a metal-made tank.
These tanks are translucent and have visible markings that help you gauge the remaining liquid inside the tank.
Water and Chemical Mixer
The tow-behind sprayer has two chambers to let you hold chemicals and water separately. You can set up the desired concentration by setting up the mixing ratio between water and chemical.
We find a sprayer with a concentration tank capacity of 2 gallons and a water tank capacity of 25 gallons to be the right fit for average use.
Boom sprayer comes as an attachment to the sprayer. It has multiple nozzles to cover larger areas in each run. These are a great option to have whether you want to spray in the large bulk of land or a small farm lot.
The boom sprayer attachment is available from 4 inches to 30 inches in length and has up to 18 nozzles. The boom sprayer's main benefit is that it can be easily mounted and have multi-system irrigation capabilities (wet booms).
If you're buying it as an attachment option, check with your manufacturer manual and ensure that it's compatible with the storage tank.
The nozzle is most often overlooked when it comes to choosing a sprayer. Nozzle plays a significant role in adjusting the spray rate and the pressure inside the tank.
Nozzle tip comes with different patterns that allow you to spray more efficiently and evenly. Follow these guidelines when choosing a spray nozzle type:
Conventional Nozzle: It's suitable for pressure above 40 PSI. At lower pressure, the pattern collapse, and you get uneven spray distribution.
Low-Pressure Nozzle: It works under low pressure, for example, below 40 PSI.
Hollow Cone Nozzle: It generates a solid spray circle and distributes liquid evenly over an area. You can change nozzle settings and obtain a spiral, axial, or tangential spray pattern.
Misting Nozzle: Misting nozzle is great for generating a uniform pattern. It mixes with air and sprays uniform but small quantity solution to plants. It's useful when you're spraying herbicides or insecticides.
Solid stream Nozzle: Solid stream nozzle creates a straight jet pattern that produces high impact spray. It's a good option to spray long distances or use it for cleaning purposes.
The pressure gauge visually tells you the amount of liquid inside the container, including the flow rate, speed, and tank pressure. A large size pressure gauge dial makes it easy to read even in low-light conditions.
You should keep in mind that pressure inside the tank fluctuates a lot. A pressure gauge mounted on the pump indicates the flow rate. You should be aware of where pressure is measured within the sprayer.
A pressure gauge that is visible from the seat of the tractor is a great option to have. You don't have to stop and get down to check the pressure inside the tank.
An oil-filled pressure gauge gives you a correct reading as oil reduces the noise of bouncing of the gauge needle.
Most pressure gauges provide you readings in both bars and psi. You should check if the sprayer pressure gauge displays the reading that you're comfortable with.
Also, ensure that the pressure gauge returns to zero when the pressure is released; otherwise, you will get the wrong pressure indication.
In a tow sprayer, the storage tank is mounted on wheels and pulled by ATV or a lawn tractor. The wheels need to have good traction and withstand the full load with a filled storage tank.
The towing wheels can be air-filled or pneumatic. The air-filled wheels give you a very smooth ride, which is essential when carrying a liquid solution in the tank. A bumpy or rough ride could result in the spilling of liquid inside the tank.
The pneumatic tires are great if you're spraying at rocky or uneven surfaces that may cause a flat tire. Ensure that the wheels are of the right size to get a smoother ride.
Most sprayers have wheels that range from 12 to 25 inches in size. If you know you will be spraying at a smaller and smoother surface, choose small-sized wheels as it makes it easy to maneuver.
Universal mounting bracket
When using a tow-behind sprayer, you have to attach it to a tractor or ATV with a mounting bracket. The mounting brackets come in different shapes and sizes.
If it's not compatible with your current tow hitch attachment, you either have to buy an extension or change the hitch.
You can attach a universal hitch mounting bracket to any powered vehicle. It's a great money and time-saving feature that is worth considering.
How to clean sprayer after use
You must clean the sprayer after use. It prevents any clogging in the nozzle and improves the life of the storage tank. Follow these steps to clean the pull-behind sprayer.
Step 1: Remove the pull behind sprayer for the tractor and park it on a flat and stable base.
Step 2: Drain any leftover liquid from the storage and close the valve again. Make sure you follow the proper regulatory procedure to dispose of any chemicals such as herbicide or pesticide.
Step 3: Using a hose, sprinkle clean water inside the tank. You can use a pressure washer or garden hose to wash and rinse the tank.
Step 4: Depending on which chemical solution you used, you have to use the right cleaning agent. You can check the solution package that will tell you the recommended cleaning agent.
Prepare the right amount of cleaning solution with an agitator and fill up the tank with a cleaning agent.
Step 5: Let the cleaning solution settle inside the tank for 6 to 8 hours to clean inside the tank properly. You must not rush the process to prevent later on contamination.
Step 6: Remove any nozzle, screens, or strainers from the unit and place them in a bucket with a cleaning agent solution.
Step 7: Use a brush to wipe off any dirt from these removable parts and wash it with clean water. Use the freshwater to drain the tank and rinse it thoroughly. Keep the top lid open to get the tank dry from inside.
Step 8: Reattach all removable parts, and your sprayer is ready to use again.
Maintenance Tips for pull behind sprayer
You can extend the life and functionality of pull behind sprayer by following these tips:
You will need this connection to power up the compressor and towing lights on the sprinkler. Extend the hose to get ready to sprinkle the solution.
Troubleshooting tow/pull behind sprayer
If you're not getting proper flow from the nozzle, you have to make sure the liquid is left inside the storage tank. You can also check the pressure gauge to ensure the compressor is working correctly.
Sometimes you need to recalibrate the tow-behind sprinkler. The calibration is straightforward as you need to fill the tank with water and set the nozzle at a low drift position.
Let the water run for a minute and store the running water in a bucket. Measure the amount of water in the bucket, and it will give you the flow rate. Once you know the flow rate, you can adjust the nozzle to the desired level.
