Rated 5 out of 5 by from Changed the way I operate my farm business. I've been struggling to find a cost effective way to spray pumpkins after the patch gets thick and the 4-wheeler with an electric sprayer can't get through it. I've been using back pack and small hand pump sprayers. The time it takes me to spray has improved from about 1 linear foot per 5 seconds to better than 1 linear foot per second. It used to take a full 10+ hours of labor to spray an acre and now it takes about an hour and 45 minutes. It also does a much better job. It mists better and turns the leaves over to help fight downy mildew. I found it to be light weight and plenty powerful. I rarely use more than half throttle. Works good on my small vineyard of 600 vines too.Southwest Virginia Farmer

Rated 3 out of 5 by from This model has problems I have been using the SR 450 for over 7 years and had little problems with them. This year I bought the SR 430 because I do not need the duster feature. The first problem is the when you get low on liquid in the tank it starts blowing air with the liquid and foaming up the feed line and pulsating the feed. The second problem is the fuel line will vapor lock when hot. This happens about 7 to 8 minutes after you cut it off after spraying in hot weather. If you refill ant start the blower quickly your fine if not it has taken over 30 minutes to get it to crank. This problem has cost me more than the $100.00 dollars I saved not getting the SR 450.

Rated 5 out of 5 by from Amazing! This sprayer is amazing! This is the best one out there. I have years of experience with the 200 and the 450. The 450 has a major flaw (If you want my un-solicited opinion). The 450 has a tank that you can remove and switch around 180 degrees if you wanna switch between a granular or liquid pesticide. The problem is that if you use it commercially and leave liquid in it while traveling, the lateral motion of the liquid sloshing around will eventually wear out the gaskets that seal the tank. I don't care what you do after that happens you will never get a good seal again, you might as well throw away the whole thing. So if you have the 450 make sure you use all the liquid after every use.Anyway I purchased this (430) blower because the tank is permanently mounted to the backpack. So far I love it and haven't seen any flaws. It is just a larger more powerful version of the bulletproof 200.Oh, and another point is always use premium gas in any Stihl. They get really tempermental otherwise.

Rated 5 out of 5 by from You won’t be sorry! I started with an sr200 about three years ago and was super pleased with it then it needed some minor service and I was told it would be 4 weeks before I would get it back due to a long line of customers ahead of me. So while I was at the shop I decided to by the sr430 to use in the interim. I was impressed with how much stronger it was. Sure it was heavier, but somehow felt more comfortable. I have a pest control business and use this thing constantly with only one issue. The issue is that when I use it for a long period of time(25min) it has been difficult to get started again on a hot day after sitting for 15min or so on the ride to the next house. Not sure if it’s just a little over heated or what. Haven’t heard a good reason why yet, but if I let it sit for 30 min it will start right back up. I use 93octain, non ethanol gas, and stihl synthetic oil. I still love it and wouldn’t consider another brand.

Rated 5 out of 5 by from just bought I love this sprayer and the product you can control the volume nicely......the only downfall is heavy....28 dry then about 5 total gallons of liquid bring this close to 70 lbs.....I set mine on the back of my pickup. easy on and off that way....I bought for spraying for bugs. I own two homes and also will use it to wash siding, spray roof anti moss material, fertilize tree's....etc

Rated 5 out of 5 by from First time out on my own lawn. I got my license to spray for mosquitoes and chose this sprayer over all the others. Not just because I like Stihl. It took a little getting used to with the amount of product to dial in and remembering to shut the solution valve off. But after finishing my yard I'm headed out to make some money with it. I will protect the honey bees.I wouldn't say all my Stihl equipment is perfect, but I can count on it 99% of the time and that's important when you run a business and need your equipment to work.

Rated 4 out of 5 by from ok i ran 6 of these all summer they do ok, but when it gets hot, the have issues starting even when running all day. Vapor lock i suspect is the issue. They are a bit particular with the blend of fuel, we were very careful to use 91 octane, no ethanol gas and mixed it ourselves as close to perfect as possible. Never broke, just running issues, had to rebuild carbs a few times but they ran 50 plus hours a week easy. these could use a much better designs backpack pad, larger as in wider thicker shoulder pads, and a hip belt, padded would be good as well. 8 to 10 hours a day up and down hills ect it wears on you. a padded hip belt would seriously help along with a better pad design.

Rated 4 out of 5 by from Does the trick.for me I bought the SR 430 to spray my apple trees. It works great for the purpose which I intend. Yes it's heavy, yet it's manageable once on your back. There's no way to get around the weight. It's going to be heavy. On the positive side it works so well I do my trees in half the time. I have thought of putting it in a cart or on one of my ATV's Anyhow I'm please with it. I wanted serious tool, not some piece of junk to spray trees which many retailers seem to be selling for hundreds of dollars. This machine can also be used as a leaf blower in the fall. The way I look at it you get two tools in one. Oh and by the way my local Stilhl dealer was great. Stihl isn't inexpensive but you get what you pay for. I own other Stihl products and have been happy with them also.
