Field King Backpack Sprayer is a lightweight, powerful machine perfect for spraying weeds and other small plants. It is a great tool for those who want to maintain the garden but can’t be bothered with mowing the lawn.
This article will help you understand what the field king backpack sprayer is, how it works, and why this is an important piece of equipment for the beginning gardener.
This 4-gallon sprayer model is a lightweight, easy-to-operate sprayer perfect for small and large jobs around the home, garden, farm, or ranch. If you have a large job, your only option is to get a larger pump sprayer or rent a sprayer from a local business.
This model is a unique way of managing weeds, insects, and other pests in your garden. With this model, you can quickly eliminate weeds, pests, and insects without damaging your plants. Let’s have a look at the main features.
- Internal, No-Leak Pump promotes safety when using chemicals with its interior, non-pressurized ergonomic design at an affordable price.
- A pressurized flow pump delivers up to 150 PSI.
- The premium, lockable shut-off requires the activation of a pressure relief valve. This safety feature will not allow for overpressure or underpressure in the system. It can help prevent leaks from pumping out chemicals before finishing jobs.
- The 21-inch poly wand with high-quality Viton seals can handle wet powders and liquids, making it ideal for all applications. It will do an excellent job of replacing an internal piston and diaphragm backpack.
- This model is safer than other brands. The simple access pump is designed to make changing your water treatment system seals as easy as possible. The pump comes with four different nozzles that allow you to completely clean and flush your system.
The multi-purpose Spray-Mixer has many benefits. It can mix liquid mixtures, quick-dissolve powders, and even water-soluble solutions. This machine can also operate in reverse, mixing powders or liquids into water.
The uniform spray pattern is a secondary benefit of this machine because it allows for more accurate application. This machine has a test report showing it can handle up to 1 million mixing cycles without failure. You will get a reasonable flow rate and liquid filtration
Internal Pressure Chamber
with a capability of reaching up to 150 PSI, the spray pressure chamber is durable, must-have equipment that will help you reach hard-to-reach areas. It is 65% more substantial than other backpack sprayers. It allows you to create more precise cone spray patterns and perform more effectively in your work.
No Tools Requires
The 190328 patented gear pump is designed with minimal interruption (60% less) and can be repaired in minutes without tools. All these pumps are built with high-quality, durable components that can withstand outdoor applications’ abuse. They are durable and will exceed your expectations.
This large holding tank is ideal for more considerable debris removal with a large opening and filter basket while filling. The single-way valve stops leaks if the polyethylene tank is on its head.
Cleaning out the sprayer is a good idea after each use. Once you have finished the job, it is best to empty the canister and clean up the other machine parts.
- To clean a pressure washer, perform the following steps:
- Fill the polyethylene tank with clean, cool water.
- Place the tank in the machine’s center and fill the rest of the hopper with water.
- Please turn on the machine and allow it to run for at least 30 seconds.
- Spray the tank and hose with clean, cool water.
- Let the water drain out of the pump and hose while turning off the pressure washer.
- Remove the tank material from the machine and empty it.
Difference between the 190328 and the 190348 backpack sprayer
The 190328 backpack sprayer is the most durable model on the market. It contains an adjustable padded comfortable shoulder strap, a full support waist strap, and chest snap belt, an adjustable back pad, and a foldable pump handle for easy transport.
The 190348 Field King model is the most transportable backpack available. It contains a deluxe padded harness, a full back pad, a comfortable waist belt, and a pump handle for easy transport.
These models have a no-leak pump design and even a dual-function strap clip to ensure safe storage. The 190328 model also has a changeable filter and four excellent nozzles for many applications.
Pumping is convenient and easy to use. With a large spray tank, you can spray with less effort, and the nozzles ensure consistent pressure. A few users complained about the noise, but this model has a large fuel tank capacity and a pitcher that can be used on either side for both left and right-handed use.
As a wetting agent, this sprayer is a natural way to refresh your product, mainly when used with our Agitator bottle. When you pump, the piston and paddles move the solution around to mix it with the water. In addition, this sprayer is made with a rotating agitator, which makes it easier to ensure that you do not lose any of the solutions during storage.
What is the capacity of this backpack sprayer in gallons?
The polyethylene tank can hold up to 4 gallons of liquid. The markings on the sides of the tank can indicate the level of liquids contained. If it’s complete, it can balance 50 pounds. To place it behind, you can hold it in your hands and climb into the connector attached to the top of the tank.
Will this model work with organic fertilizers that contain some small stuff?
Use high-performance paint that requires a fine paper filter. The best way to use organic fertilizers is with a diaphragm-type sprayer. A piston-type of sprayer won’t work as well.
How far does this 4-gallon tank model spray?
I can reach 8-12 feet into the air with the adjustable nozzle. Using a suitable power nozzle, you can make your garden smaller and spray higher up. Pumping power nozzles is challenging and requires a lot of strength. It depends on what nozzle you have and what tip you used.
What is the length of the padded shoulder straps?
At first glance, this padded strap-on sprayer looks like a cheap device, but it’s very comfortable and long. I’ve only used it once so far, and it’s necessarily long for me. With a bit of practice, you’ll be able to get the hang of how to use it.

Can you use the remaining weed-killer solution without causing any harm to the plastic container?
I am unsure if it would damage the plastic or cause problems with the seals. You can clean it out by filling it with water and spraying it down. Also, You may put dish soap in there to help break down any residue from harmful chemicals.
