Are You Ready for a STIHL?

HS 45 is rated 3.8 out of 5 by 101.
Rated 2 out of 5 by from Stay away. Needs improving I own all stihl equipment for personal and business use. I have had no issues with anything I have ever purchased. But these HS45 hedge trimmers are ( for lack of a better word) horrible. They don't cut cleanly and this is after trying them on a variety of bushes and shrubs. It shows especially on yews and boxwoods. Maybe it's the teeth, maybe it's the design of the blades as a whole. As well once they get warmed up they are difficult to start and I trim 100s of bushs a year. Highly disappointed. I would suggest to anyone thinking about purchasing these to not and go to the next level above.

Rated 4 out of 5 by from Well balanced performer. I bought my HS 45 because I have hundreds of feet of hedge and many shrubs around my home. I quickly tired of dragging electrical chords and underperforming electric trimmers. I bought this trimmer almost on a whim when I saw it at my local ACA Hardware Store.Having been a customer and fan of Stihl for many years, I had no doubt about the quality and performance expectation. Which brings me to that missing star. The motor se ms a bit finicky when it comes to ambient temperature and hot/cold starting. I just can’t seem to find the sweet spot for the carburetor adjustments.

Rated 4 out of 5 by from Despite alot of negative reviews.. Despite alot of negative reviews, I was slightly hesitant but decided to give the hs45 a try and get rid of my corded big box store special... I had no issues with starting or cutting... the blade were very sharp upon purchase... I keep my yard very manicured and use it about every 3-4 weeks... again no issues.. I have only ran Stihl moto mix fuel, and clean with the stihl hedge trimmer solvent/lubricant after each use... over all I am very happy... I recently switched all my yard tools over to stihl and have been very happy with all..

Rated 5 out of 5 by from great i am kinda bummed about my new Stihl hedge trimmer. It cleanly and efficiently does all I ask of it. Now I have NO excuses for not trimming our bushes, which means less time fishing and kayaking. I should have known better than to buy another Stihl tool.

Rated 1 out of 5 by from Very disappointed in this Stihl product Last year I bought my 2nd Stihl chain saw, an MSI 180C. Really came in handy during Hurricane Irma! Great piece of equipment. I am slowly replacing my other yard equipment, and was either getting a blower or hedge trimmer next. I got the HS 45 trimmer, and and very disappointed in its lack of power, and therefore poor performance. It seems to tear, instead of cut. Fully charged, but not up to the job. I'm back to using my old Ryobi.

Rated 5 out of 5 by from Plenty of power We have been using the HS 45 trimmer for two seasons and are well pleased with the overall performance. The engine has more than enough power to cut the toughest overgrown shrubs and the blades cut cleanly without tearing the leaves, even on holly bushes. There have been no problems of any kind with the trimmer, it starts every time as long as the starting procedure in the owner's manual is followed. The guys where I bought the trimmer showed us all about starting and using it when we took delivery and there has never been a problem.

Rated 1 out of 5 by from HS45 Run Issues Should Be called Back! Purchase new and first time owning a Stihl USA from my local dealer because of their recommendations, From the time starting it as per own manual it would start, idle, and try to go full speed only to bog down and never reach full speed and this is with warm up after playing with the choke off to 1/2 to Off it would finally go to full speed but let off and it bogs again. Turn it off for a while forget it never starts. I have attempted to use this 5-6 times now and today is the last I give up on STIHL and they should be ashame of selling these defective HS 45 Trimmers! I will be trading in, selling or putting it in the garbage can and purchasing another brand.

Rated 1 out of 5 by from This product very unreliable to run Looks brand new, Bogs down when using it, thought it was the gas mixture, NOT the problem, I have all Stihl equipment and the gas works fine in everything else, I love Stihl products, but this thing is not what I expected, Stihl needs to recall this item, and save themselves the embarrassment, and protect their image. This is a bad one guys! I've been inconvenienced relying on this thing to run, and it bogs down, or wont start.

Rated 1 out of 5 by from Don’t buy! Bought this trimmer because everything I own is stihl. Ran only descent first time I used it and have carried it back to dealer 3 times and every time they blame the gas which is the same gas I run in all other products. Doesn’t crank and when it does it just bogs down. Dealer tried new carb last time and back to the same, doesn’t crank. Last time I tried to use it cranked but bogged. Still looks brand new with only couple hours of operation. Garbage!

Rated 1 out of 5 by from A problem from the start I have purchased many Stihl products over the years. The HS45 is the only product I have regretted purchasing. This trimmer started the first couple of times I used it and has never started since. I have a friend who owns a landscaping company who was over the house with his crew doing some spring clean up. I asked him about my trimmer and he had the same story. He had purchased 3 or 4 HS45's and couldn't figure out why no one used them. He later found out that the workers could never get them started and used their old machines. He was able to trade them into one of the neighborhood shops for a more expensive model and didn't have an issue after. My friend asked one of his workers to try to start my machine. Even though he didn't speak English, he shook his head when he saw the model and said "garbage".

Rated 1 out of 5 by from Bent blade right away The blades are weak, and expensive to replace. I have a brand new one I gave to the repair shop because fixing it was 3/4 of the price of new. Disappointing purchase.

Rated 5 out of 5 by from runs like a dream, cuts really good! I purchased this one to replace my old HS45. It is the best hedge trimmer I have ever used. Easy to handle with the 24in blade. It feels like it has less vibration then my old one when it was new.

Rated 5 out of 5 by from Works how I need it too. Light weight and does a great job trimming hedges. A good lasting battery charge as well. It is just what I need to do the home trimming and shaping I have. I truly like the fact there is no gasoline (noise and hassle to maintain) or electrical cord (could be dangerous) necessary.

Rated 5 out of 5 by from Quality and Ease of Use - What More Could You Want? Like many of the folks writing reviews here, I too struggled with cheesy, underwhelming electric trimmers for years. After my last trimmer died, I went out in search of a quality alternative. I already owned a Stihl backpack blower and chainsaw, so I naturally gravitated toward the Stihl trimmer. I have not be disappointed in the least.It's well-built- reliable, very easy to start and man does it make trimming bushes a breeze. What took me so long to abandon cheap electric trimmers for the gas-powered alternative? There's simply no comparison. It takes a fraction of the time to trim hedges now. I couldn't be happier. I jokingly asked my wife if she knew of anything in the yard that needed trimming! It doesn't phase me at all anymore!If you're debating whether to invest - I say don't hesitate. A gas-powered Stihl is the ONLY way to go. I'm only sad that I didn't make the jump sooner, and save myself all the time and aggravation years ago!

Rated 1 out of 5 by from 24 hours after purchase back to store and to shop Bought it on a Wednesday from local Big R (sales person took it to the back room to start it as per protocol and returned 15 minutes later out of breath and stated that this was a cold blooded machine in that it would start but would not come to full speed until totally warmed up, then stated that it ran fine) took it home and on Thursday tried to use it only to have issues starting and keeping an idle. When I did start the machine as soon as I touched the trigger it would die. Had to feather the trigger to get to full speed and found that if I ran it at full blast it would work fine. The unfortunate part is that full speed does not work as you climb a ladder, so I would allow it to go to idle, climb the ladder only to have it die upon touching the trigger. Here is the kicker, this was on the gas that was put into the machine from the dealer. When I refilled the tank same issues and again for third tank. A two hour job in six hours, a machine that would not idle or run as expected. Took it back to Big R and told them of the issues and a different sales rep for stihl said they could try to adjust the machine and said I could bring it in. We walked out to the parking lot and I handed him the machine and he went to start it (I tried not to laugh) and after about five minutes of pulling he asked if I had any suggestions on starting. I said try full throttle with choke off and it kicked over at full speed, he reduced it to a idle and touched the trigger and it died. Would not start after that. I was told that they would look at machine and I told him to ask his co-workers and take time to make the machine right. Informed that if they could not make it work right they would have to send it off to another location but this would be a 5 week turn around. 300 dollars for three tanks of gas of use (less than 24 hours of ownership) and back to the shop, at this time 1star if it get fixed in a short time may increase rating because stuff happens. I felt that as soon as I paid for machine I was on my own, no exchange, no return, you bought it we will see if we can fix it. I would like to give Big R a chance but I am not feeling warm a fuzzy about my chances about a good outcome. I initially had gone to Big R for a higher priced unit hl56 but was told they did not have one and it was a clearance item. I guess I should be grateful that I did not pay more for possible same issue. I will wait and see if it can be fixed or what option are left to me. I opted for the two year warranty with purchase of oil which I felt was a good deal but with this machine maybe it is a requirement.

Rated 5 out of 5 by from Product makes for quick work. Great product like all STIHL products. Easy to start once you understand the process. Push side button in to lock trigger... push primer 3 times, put lever to full choke and pull cord. Once it pops take full choke off and pull cord again a couple times. Once it starts do not pull on trigger throttle. Leave it warm-up. for 10 seconds or so. Pump throttle and should be good to go. Be sure to drain gas out from one season to next.

Rated 5 out of 5 by from A win for Stihl! I've owned this hedge trimmer with 24" blades for ten years now. It has been exceptional. It gets fairly heavy use from me about 7 months of the year. I just this week had the blades sharpened for the first time. It still cut ok, but I had a couple areas in high use zones of the blades that looked a little too worn, and didn't quite cut like in the past. I've been very happy with its power, ease of starting and blade life!

Rated 5 out of 5 by from Perfect for around the house Lightweight, easy to start, and does the job around the house. I was looking at a bigger Stihl hedge trimmer but for the price tag I couldn't be happier. I'm sure I will get many years use out of this. You can't go wrong with this model for around the house. My wife uses it also.

Rated 5 out of 5 by from HS 45 Year Round Use in Florida When we moved to Florida it quickly became apparent that I needed a serious hedge trimmer. I went to STIHL and picked up the HS45. The expense was not completely out of control for what is honestlt a pro grade tool with a "homeowner" label. I see many reviews with, hard to start or carb issues, but I have not experienced this with my machine. I keep the blade sharp and oiled between uses, and run it on STIHL HP Ultra mix and 100LL Aviation Fuel. It and all my yard machines seem to run better on this fuel and fuel mix. They seem to be a bit more eager and I don't seem to develope any issues as written in other reviews. Either way, I think this machine is worth the investment and if properly cared for should perform well and last long.

Rated 5 out of 5 by from Spectacular time saving idea No cords, plenty of power and this thing saves me so much time that it will pay off likely after the 2nd time I've used it. I can tackle a 40' long hedgerow and shape it in about 20-30 mins. with the thing. Otherwise, I'd be fiddling around with a cord or swapping batteries out in an underpowered model and spending who knows how long trying to get the same time done. I'd be exhausted, frustrated no doubt and likely not be able to get nearly as much work done in the same day. I can speak highly enough about this rig for taking care of small to medium sized hedges and even some pretty thick stuff, but if you want larger than you need to buy larger. Cut what the machine was made for and I'd say this thing will last indefinitely, plus I bought the special oil for it to get the rebate and warranty and I only poor the stuff that was specially made for 2 stroke machines. No buying gas and mixing it anymore.

Rated 1 out of 5 by from Impossible to start!!!!!!!!!!!!!! If your lucky enough to get it fired, just touching the trigger will solve that, it dies immediately. Dealer says " bad gas". Using motomix and no improvement. Able to get to run only two times since I've owned and both times I finished th job with hedge clippers. Lemon from day 1. One more trip to dealer then it's goodwill time. I have three other Stihl products without issues.

Rated 2 out of 5 by from Sorry! Beware! This trimmer has been constantly at the dealer getting serviced because it won't start. It can't even sit for 45 days without an issue. I do not recommend it since it takes several days at the dealer to wait for a repair.

Rated 5 out of 5 by from Great trimmer Bought this trimmer this week to trim Holley bushes and boxwoods around my house. It works like a dream compared to the previous 2 electric hedge trimmers I had before. Used to dread stringing extension cords around the house, not to mention cutting them in two when they got in the way. I own a Stihl line trimmer and chain saw and they have been so reliable that when it came to this purchase I didn't even shop around. I know I could have gotten another brand cheaper but stihl products have never let me down and I'm confident the HS 45 won't let me down either.

Rated 1 out of 5 by from Stihl HS 45 Own several Stihl products and normally satisfied. The HS 45 is constantly down with carb. problems. I get it fixed it, last a few runs, then the same issues. Hard to start, won't stay running. This Stihl product is nothing but a problem for me. I have searched the net and found numerous consumers complaining about the same issues with the HS 45, would not recommend this to others.

Rated 1 out of 5 by from won't start I own several STIHL products, and this one is just not one I would recommend to anyone. I've owned it 5 years now and been in the shop 7 times all because it won't start or once it starts it won't continue to run. I don't have time to continually take it into the shop on top of the money it's cost me to get it fixed all the time. If there was a trade in offer I'd be there in a second to get rid of it.
