Review: Excellent sprayer, gets the job done - I have 3 different size tank sprayers (1,2,3 gallon) and was tired of carrying them around the farm. We have a 300 ft barn lane and 400 ft drive with a half circle turn around with gravel surface. I use 6 gal of spray to keep weeds/grass out of drives. We have 3 pastures totaling 20 acres surrounded by woods and 26 acres of woods in a woodland management plan. I needed a sprayer that I could use to kill invasive species along the pasture edge and in the woods. This sprayer does the trick. It worked perfectly right out of the box. The wide mouth on the tank with a screen allows you to pour chemical easily into the sprayer and the screen catches anything that might fall into it. I was able to take water, chemical and sprayer in a trailer to the back of the property, mix it the field and spray the pastures edge. I used 11 gallon of chemical first time I used the sprayer and it worked great. No leaks, 5 or 6 pumps pressurizes the tank with excellent spray coverage. With the wand I can reach 10 ft high and the spray is another 3 ft so I can reach places I couldn't reach with the hand held sprayers. Having the sprayer on your back is much easier than carrying around a tank and having to stop to pump 12 or 15 times to keep good pressure. I thought I would use more chemical due to the excellent spray coverage but I was pleasantly surprised that I used less chemical than before. I was able to spray about 1000 ft of pasture edge with the 11 gallons of spray. We have serious problems with Chinese bittersweet, grapevine and privet so I use Crossbow in the sprayer. Clean up was easy, the filter on the wand is easy to get to, the nozzle is easy to remove. The one thing I can't use it for is walking thru brush to get to invasive plants that are well hidden but I knew that before I bought this sprayer. With a tank full of spray on your back it is hard to maneuver in close quarters. If you are looking for a good sprayer, at a fair price that does the job intended then look no further than this sprayer. It is well worth the investment. One caveat is that any piece of equipment is only has good as the maintenance so I would encourage you to clean after every use, use vaseline on the o-rings and take care of the equipment you purchase.
Review: Best sprayer I’ve used!! - The Field King Backpack Sprayer is a professional sprayer that works great for our lawn and garden needs. The four-gallon capacity tank and its easy to pump tank makes spraying a large area a simple and effortless task. The padded shoulder straps, a waist belt with built-in lumbar support ensure extended use comfortable even when full. Great product and value for your money.

## Questions & Answers

**Q: how does it differ from 190328?**
A: The Field King MAX 190348 Backpack Sprayer is an upgraded version of the Field King Pro 190328 Backpack Sprayer. Here is a list of the Field King MAX 190348 upgrades: 1) 21" stainless steel wand with chemical resistant poly lining. 2) Deluxe padded harness with back pad and lumbar support, adjustable shoulder straps, waist belt and chest cinch strap. This backpack harness ensures all-day comfort while you work. 3) Fold away pump handle for easy storage. Both backpack sprayers are equipped with the internal, No Leak Pump which prevents liquids from leaking down your back. The internal pressure chamber can reach up to 150 PSI allowing a straight stream to reach 30 feet (dependent on the chemical being sprayed). Also they both have Viton seals for resistance to harsh chemicals and dual filtration to prevent clogging. If you have any questions, please feel free to contact our friendly customer service at 1-800-311-9903. Thank you for your interest in our products.

**Q: does this have a built it agitator and can wettable powders be used in it**
A: No agitation. It’s a manual backpack.

**Q: So i have a pest control company and i was looking to add a back pack - any pco out there using this or i am open to other suggestions??**
A: HI,
This unit is ideal for use with cleaning solutions, disinfectants, stains, sealants, fertilizers, herbicides, and fungicides to help beautify your outdoor areas. I don't see anything saying that it can't be used for pest control.
Thanks!

**Q: does this version also come with the 25psi regulator?**
A: It has a pressure regulator, but I think of it more as a no drip regulator that prevents the the spray that remains in the wand from dripping if the pressure gets below 25 psi.  It also ensures a clean spray pattern as most nozzles don't do a good job of dispersing the spray below that pressure.

### ⭐⭐⭐⭐⭐ Great for large spraying projects. Saves time and comfortable to use.
*by P***L on June 26, 2025*

This is way better than the stop-and-pump sprayers if you have a big project. First time filled it all-the-way up and discovered it was awkward to put on - sore shoulder and arthritis. Three gallons about right for me. I fill it and put it on a bench and back into it and I'm good to go. Used it to spray paint lawn. Worked great, just keep the pressure up which is easy with handle pump. Unit did not leak and held pressure well.
