Why We Like It – Professional 190328 Backpack Sprayer Killing

The Field King Professional 190328 Backpack Sprayer is perfect for farm tasks such as killing weeds or spraying fertilizer. It’s got a no leak pump design to protect users from chemicals, heavily padded shoulder straps for easy carrying, and a changeable spray nozzle – features that earn it a second position on our list of the best backpack sprayers.

  • High 150 PSI pressure rating

The Field King Professional 4 gallon backpack sprayer is arguably one of the best backpack sprayers in the market, and is second only to the Chapin 61900 4 Gallon Commercial Stainless steel sprayer. The 4 gallon sprayer features an internal no leak pump design, and this is to prevent any chemicals from leaking down your back as you’re spraying. With an internal piston pump that delivers pressures of up to 150 PSI, you should be able to get to hard to reach areas during spraying, and to help you further in doing so, the sprayer offers a variety of up to 4 different nozzles to choose from. There’s the brass adjustable nozzle, 2 flat fans nozzles, a foaming nozzle and tee jet nozzles, and all four are chosen depending on the kind of work that you want to do.

The design of this FIeld Professional back sprayer is pretty much identical to that of the Chapin International 61500 ProSeries Translucent backpack, so there isn’t much that sets the two apart. The pump handle on this 4 gallon backpack can however be reversed for either left or right handed use, and its 21 inch poly wand comes with an intricate storage handle where you can fasten it instead of leaving it on the ground when not in use. As you should be able to see, the padded straps on this sprayer are significantly thicker compared to what you’ll find with other models, making it perfect for both shoulder and lumbar support.

The internal piston pump that you’ll find inside the Field King Professional’s large tank sets it apart from the Chapin International 61500 ProSeries Translucent backpack sprayer in that it keeps liquid solutions well mixed and ready to spray. It’s no leak pump design & viton seals are also quite essential especially for those that tend to use chemicals, as it helps users avoid any cases of skin corrosion. The tank has a fairly large opening to allow for easy filling, and with a filtration basket inside, you can rest assured that no debris will get mixed up with whatever solution you’re pouring inside. We wish that the sprayer came with a steel wand instead of a poly wand, but other than that, we’re pretty satisfied with the sprayer, and not really surprised that it takes up second place on our best backpack sprayer list.
