When full, it weighs 50 pounds. The back pack makes it feel like less than that once you have it on your back. This is most easily done if you set it on a bench top or table top, and then "slip" into the harness. **Q: Has anyone had any experience with using this sprayer for a stain or oil based product for spraying/staining a split rail fence?** A: use a $20.00 plastic cheaPO 1 gallon pump spray worth it for large deck saves serious time ive done this 5 plus times solvents and stayin etc usually ruin pump in hours make sure finish same day b/c next day pump might be junk **Q: what is the difference bet 190328 and 190348** A: The 190328 Field King backpack has adjustable padded shoulder straps and durable poly wand; whereas, the 190348 Field King Max backpack has a deluxe padded harness with a full back pad, wide support waist belt and chest cinch strap. It also features a 21" poly-lined stainless steel wand and foldable pump handle making it easier to transport and store. They both have the internal No Leak pump, Viton seals, lockable shut-off with removable filter, and 4 nozzles. Please let us know if you have any other questions. You can also call us at 1-800-311-9903. Thank you for your interest in our products. **Q: will it work for Organic fertilizers? Using Fertilizers that have some tiny solids.** A: I haven't used it for organic fertilizers but as long as the solids are soluble in water, it should work. If they are not soluble, they will likely clog up the spray head. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***T on 9 November 2025* As described. Nice quality ### ⭐⭐⭐⭐⭐ Review *by O***O on 28 September 2019* 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 *by T***G on 5 July 2021* After going through 3-4 different pump sprayers from Bunnings Australia, I found this recommended online from many US based websites. The sprayer came well packed and was easy to assemble, I was only required to add the Pump handle, attach the spray wand and the cone tip. Additional seals and spray configurations are also provided which is nice. The Instructions are well written and legible. I quickly added Round-up, detergent and some dye and was pumping and spraying my front and backyard in no time. There were no issues with leakages at all and the pump lever action is satisfying to use. Functionality: 5/5 Durability: 5/5 (Used twice so far, but it didn't blow the seals after use, which has beaten all the competition I've tried so far) Features & Accessories: 5/5 Honestly, this is the best spray I've used and is worth the investment. It looks easy to maintain and repair also. Don't bother with a el-cheapo that'll break after 1-2 uses. ## Frequently Bought Together - FIELD KING 190328 Backpack Sprayer, 4 Gallon, with Internal No Leak Pump Design Delivers 150 PSI - RM43 Concentrated Extended Control Weed Killer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/383880088-field-king-professional-190328-no-leak-pump-backpack-sprayer-killing](https://www.desertcart.co.za/products/383880088-field-king-professional-190328-no-leak-pump-backpack-sprayer-killing) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-07*
