Husqvarna 4 Gallon Backpack Sprayer

the only thing I regret about the Husqvarna sprayer is that I didn't buy one sooner. I have used it four times now, it works better than great, the back pack set up is perfect in that it feels great, offers great support and allows you to wear it with comfort. The sprayer is a joy with easy to pump, very good reach and an assortment of nozzles for spray density and volume. This sprayer is very well built, and a bargain for sure, you won't be disappointed

Perfect. Works flawlessly. Easy to use. No leaks. Will spray to a wasp nest on the gutter of a 3 story building. No kidding. Fabulous tool. One complaint is pump arm DOES NOT fold out of the way for storage unless you remove its mounting bolt... so arm is sticking out and continually in the way when sitting on the shelf of my workshop. Minor issue.PS To guy who says pump handle is unusable/ wrong position: Remove pump handle bolt, put handle in correct position, reinstall pump handle bolt. Problem solved. PLEASE don't ding people (companies) unless there actually IS a problem. Yes the instructions were vague but this is an excellent product.... best I have ever used in 45 years of doing this type of work, and the handle, once set up correctly works perfectly. I have used this thing for hours at a time with NO issues and it is easy to pump.

I live on 7 acres of mostly landscaped property. That means I need to use this often. The unit is fairly light. It's comfortable on my back. The listing says the unit itself is 12 pounds. I don't think so. That must be the entire unit, packaging and all. Still, remember, with 4 gallons of water based liquid, plus the weight of the unit, you'll be somewhere around 40 to 45 pounds when full. You can pump in more or less pressure to expand or narrow your spray pattern and it comes with several different spray heads that allow for a tighter, broader or adjustable pattern. I use two different types of herbicides in it, one for grasses and one for broad leaf. I rinse it three times when going between the two types. On the last rinse, I fill it half full, pump it up and spray out the hose with fresh water until it runs out of pressure. I usually do that twice and then dump the remaining water, and that seems to work to avoid damaging plants or grass. The orange top cap has a black rubber button in the middle. It's just a nub, but pressing it releases the last bit of pressure before you remove the cap. After my first full season of use, I'm really happy with mine.

The 2 included plastic nozzles are useless. Try them on dry concrete. Very uneven and worthless. The brass nozzle fine tuned should be good for spot spraying but a 1 gallon pump sprayer is far more useable for spot. With the included pressure regulator the tee jet course spray AI11004-VS red nozzle is excellent. Plug n play. Bought local at an ag store for $10.50. Tee jets are used in large farm sprayers and work great.Pros:Pretty well padded.Pumping is not too bad.Metal wand works well.Regulator works ok.Seems solid.Cons:Package wide open with tag open box. Amazon you really do suck at packaging and politics.Adding 1 tee jet would make usability 100% better.Pump handle bolts in for use position. Sticks out for storage. Unbolt for storage. Wrenches needed.Straps are not quick release for cleanup on bottom.Cleanup is a choir with multiple liquid sites.Using multiple chemicals is very risky because of near impossible complete flushing. Add roundup and it may be best to only ever use Roundup.With a good tee jet and single use chemical this is a solid sprayer for big jobs. For ease of cleanup and small jobs get a 1 gallon.Used for Prodiamine 65WDG(Barricade). Red tee jet high volume nozzle spreads even ~4 ft band. Yellow color residue stick to everything on sprayer. Overlap ~1.6 gallon H2O per 1000sqft. Fast spray ~0.6 gallon H2O per 1000sqft.. Spray with no sun and low wind to avoid using dyes. I did use a cheap HF 100 ft rope for large lawn area for boxing off areas with the slow overlap method.

I have bought several sprayers over the years from a small engine Echo to the cheap 3 gallon sprayers from the big box stores. If you have a large area to spray, this sprayer will do the job. It was extremely effective in spraying my moss covered roof with a killing solution and cleaner. It is relatively light weight for someone with a good back. I also saved on solution compared to my power Echo sprayer and the coverage was consistent. One drawback is that it is for close in applications. It would not be the best for spraying the topsides of larger trees.

I bought this unit because we are in the third or fourth week of a drought where I live.I use it for watering potted plants and small shrubs, substituting one or two tours with the sprayer for several trips to the spigot with my old one-gallon watering can.The directions are easy to understand, the unit is easy to assemble and use, and the overall weight is impressively low, given the fact that it holds about liters of water (4 US gallons).While I have no intention of ever filling it with herbicides or pesticides, I can see how it would be useful in that context- - nothing drips from it, and it is easy to aim it with precision and produce a highly controllable spray pattern.
