SG 20

A manual backpack sprayer for professionals that maintains constant pressure.

SG 20
SG 20 is rated 3.2 out of 5 by 92.
Rated 5 out of 5 by from Great Sprayer This is a great sprayer. I use this weekly and mine is 4 years old. It must be rinsed/flushed after each use, as ALL sprayers do. This will prevent most issues. The chemicals used break down when stagnant and clog the machine if you skip this step. If you need a quality sprayer that doesn't break the bank, this is it!!

Rated 2 out of 5 by from Great Product Until you have to change the straps This is a great sprayer until you have to change the straps. There is not enough room to bring the strap back up. I had to physically widen the strap hole by drilling it out to be wide enough. It took 30 minutes to do. Now I have a hole in my tank. I am sure it will cost more to buy just a tank than to buy a new sprayer. Whoever invented the strap system is not a good engineer.

Rated 5 out of 5 by from Have two of these one bought 2011 an one bought 2015 These sprayers have served me well so far with no problems and no need to replace parts. Use one to spray weed killer and the other to spray insect and plant dieses sprays on 20 fruit trees,65 rose bushes and other flowering bushes.Have had other makes of sprayers in the past. and none of them have worked as well.

Rated 4 out of 5 by from Does what it’s supposed to do I own three sg 20 sprayers I keep one for each dominant product I spray. After minor maintenance each spring I get trouble free service weekly. I would love to see a few upgrades to the shoulder harness and a belt harness would be a big help. Units are not cheap. Not for a homeowner.Appalachian Landscape & Management - Frederick, Md

Rated 1 out of 5 by from Wasn't working out of the box My brother bought this and let it sit on the shelf for a couple years before I bought it from him. Out of the box the pressure reservoir isn't working and will cost as much to fix as to just buy a new one. It's our own fault for not using it earlier but I thought Stihl had a better quality than this, very disappointed.

Rated 4 out of 5 by from Seems like a nice unit. Wish reserve tank was larger. The sprayer seems to be well built. Builds good pressure quickly, the heavy duty Continental hose should last a long time, and the nozzle is impressive too.Assembly is simple, and maintenance is easy and reasonable. My only gripe is the unit doesn't stay pressurized for long during use. Upon reading the summary of the unit, I had assumed I could pump it and use it for a few minutes before having to pump it again. If you want good flow, you are going to have to pump it constantly. This makes use rather fatiguing.

Rated 1 out of 5 by from Don't do it I bought this sprayer last year. I wanted a quality sprayer and bought the Stihl name. Sprayers aren't chainsaws. I used the sprayer only once last year. I just tried to use it again and the pump won't build any pressure. This product has a bad rating for a reason.

Rated 3 out of 5 by from This product was made cheap. I would not recommend. I purchased the SG20 4 years ago, the first two years it worked great however last year the shaft cracked and broke. I took it to my Stihl dealer and he fixed it, unfortunately it wasn't under warrant. Now going into my forth year of use and the pump won't hold any pressure. So once again ill have to have another major part replaced. Other complaints I have with this sprayer are the flimsy wand and the hose tends to kink near the pistol handle. I use the spray 5-10 times each summer and clean it out after each use so it hasn't had a hard life. Stihl makes some really good products just wouldn't recommended their sprayers.
