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.

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 ### ⭐⭐⭐⭐⭐ Backpack sprayer *by J***T on 9 November 2025* ### ⭐⭐⭐⭐⭐ Excellent sprayer, gets the job done *by O***O on 28 September 2019* ### ⭐⭐⭐⭐⭐ No leaks, One Pump = lots of spray, works really well *by T***G on 5 July 2021* ## 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.jp/products/223019586-professional-190328-no-leak-pump-backpack-sprayer-for-killing-weeds](https://www.desertcart.jp/products/223019586-professional-190328-no-leak-pump-backpack-sprayer-for-killing-weeds) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-09*
