A versatile, easy to carry sprayer.

Product Description

The SG 31 sprayer is a powerful, easily portable piece of equipment. Equipped with a 5-liter tank, the sprayer falls between the SG 11 and the larger SG 51 in terms of volume capacity. This multipurpose sprayer can be used to apply fertilizers, pesticides, herbicides, and insecticides to your plants. It’s built with lightweight materials, making it a convenient tool to carry with you both in the yard and on the farm. The easy-to-use design includes a pump handle that can be locked into place for use as a carrying handle, along with a translucent tank for optimal visibility of liquid levels. The sprayer wand comes standard with a non-adjustable hollow cone brass nozzle, and a wand holder for secure transport and storage.

Rated 1 out of 5 by from Do not buy this sprayer Nozzle not adjustable and the wand is nothing but plastic JUNK.. The handle lock button is constantly sliding onto the 'lock' position which is highly aggravating.. This is the only Sthil product that I'm sorry I purchased...'

Rated 1 out of 5 by from I give it one star because the computer won’t let me give it zero. A complete piece of plastic junk, sold at a premium price. You’ll spend a lot more time working on it than working with it.

Rated 1 out of 5 by from SG 31 is not worth buying Being a Loyal Stihl owner this sprayer does not deserve the Shitl name. Ive owned this unit for two years and already have had to replace the trigger valve assembly twice, one on warranty and one paying for. The valve cracks and leaks with no way to repair it. The wand and hose are cheaply made and the hose kinks all the time. Now I have a leaking monometer valve not holding air pressure. You cant service it, and after all the time and money Ive spent on this sprayer I thinks it time to trash it and get a Solo sprayer.Stihl should just take this sprayer off their product line. It does not do the brand Justice.

Rated 1 out of 5 by from Junk What a disappointment! I had hoped to avoid tossing out a sprayer every year like I have with the cheap ones. I’ve never had a hose come unscrewed and drench me with Glyphosate like this one has a couple of times. Connections are cheap. Even the cheap sprayers have an adjustable nozzle. This one doesn’t. Unscrewing the Brass nozzle from the plastic connector to remove the little plastic spinner is a pain and results in potential cross threading of the connector when you put it back together, especially if you’re wearing gloves. In addition, the strap keeps coming apart and is quite unreliable. The handle is easy to use though…

Rated 2 out of 5 by from Should be great - Cheap components Stihl products should be of the highest quality. Unfortunately, with the SG 31, that is not the case. The plastic wand of this sprayer has broken multiple times and we've reused the progressively shorter parts. The rubber hose has fallen apart after less than a year of service.Although it will likely be taken care of under warranty, we should expect better from Stihl.

Rated 2 out of 5 by from Plastic wand is fragile First use, plastic wand was in the side holder fell over in the back of the truck and snapped. For the cost it should last, but it didn't.
