The Field King Professional Sprayer is a product that comes with an impressive list of features that many users will love, especially its non-leak ones, which will ensure that what you are spraying is the only thing that gets wet.
Best Field King Professional Backpack Sprayer for Lawns and Gardens
By Debbie Proctor
The Field King brand is one of many that comes under the umbrella of the Fountainhead Group. They are responsible for manufacturing some of the most popular and highest-rated spraying products on the market.
Field King has a range of sprayers whose liquid capacity varies between 2 and 4 gallons, and most of them come as a backpack sprayer, making them easier to carry around.
This specific sprayer has the larger 4-gallon capacity, a backpack, and Fountainhead Group’s ‘no-leak’ design sprayers. Those who might want to use this commercially, and may need sprayers for multiple users, can also purchase it in packs of two, three, or four.
Who is This Product For?
Given its diversity of uses, many people might be interested in this sprayer. The most obvious are gardeners who need to spray their gardens, either with water or with solutions and liquids that feed their plants or deal with weeds.
Bear in mind, when full, it will be quite heavy, and while the backpack helps carry it, it may not be suitable for those with back problems or who may struggle to carry it, even with the backpack.
Other uses can be for cleaning purposes such as cars, decking, patios, pathways, and exterior windows.
What’s Included?
This backpack sprayer comes with several parts that will need to be assembled when you receive it, and that list is a long one. Rather than list them all here, you will receive a checklist when the product is delivered, which you should use to make sure you receive all the necessary components.
Speaking of components, should any break or become faulty, you can order a 044600-20nt for many of them from the manufacturer’s website.
Overview of Features
This is a versatile sprayer, not just because you can use it for jobs other than in the garden, but due to the variety of nozzle options. These include two flat fan nozzles, a foam sprayer, and an adjustable brass nozzle.
You can store the wand on the tank, and the handle is reversible, so right or left-handed use is possible. When using the wand, the lever can be locked to relieve any hand fatigue.
It is the tank that sets this sprayer apart, and for several reasons. It has a large 4-gallon capacity, but it also has paddles inside, which allow for mixing liquids, chemicals, and powders that you can add.
The tank’s pressure limit is also impressive, as it can reach 150 psi and therefore provide a very powerful and precise spray when you need it.
We must also focus on the non-leak features this sprayer has, including high-quality seals and gaskets from Viton, a brass shut-off valve, and a one-way valve that stops leaks when you turn the tank upside down.
How to Use It
As with all the parts, we will not go into a detailed explanation of how to use this sprayer simply because the instructions which come with it will do a much better job of it than we can.
As an overview, you should know that you will need to assemble much of it, including attaching the wand and nozzles, the pump handle, and the harness for using the backpack.
To operate the sprayer, you will need to use the pump handle to build pressure after filling the tank with liquid. Other operations include changing nozzles, which is very easy, and spraying, which you achieve by pressing the lever on the wand.
Pros
- Lots of non-leak features
- Internal paddles to mix solutions
- Up to 150 psi
- Filtration to exclude debris
- 4-gallon capacity
Cons
- Very top-heavy when full
- The handle is not fold-up type
Alternative
If you are looking for a large capacity sprayer, but one which gives you even more convenience in the form of not having to build up pressure in the tank manually, the Kimo 3-gallon Battery Powered Sprayer might be the answer.
It is every bit as easy to use and goes a step further as a battery-operated pump creates the pressure, so no effort is required to get it up and running, other than pressing the ‘On’ button.
Conclusion
Everyone hates leaks, which is why this Field King sprayer is so popular with gardeners and other users because of its leak prevention features. Also, it has a large capacity and is thus suitable for more extensive gardens.
