Reviews

BR 450 is rated 4.9 out of 5 by 60.
Rated 5 out of 5 by from This product is better for smaller framed people. All we have is Stihl blowers, weed eaters and a chainsaw. When the 600 Magnum came out I thought that it was the bomb but the women I work with did not like it at all and went back to the older ones. Now that the 450 came out they love it since it seems to fit better to their body types better. I'm almost 6 foot and 225 and the Magnum fits me great, where most of them are around 5'6" and 125. The power is very comparable to the 600. Now when we hire someone new we will definetly know which blower to get.

Rated 5 out of 5 by from Great machine. Amazing power! My first backpack blower. This machine really moves some air. Wet leaves are easily moved by this machine. Needless to say, I was impressed.

Rated 5 out of 5 by from Needs a chest strap to help hold the unit! Over all I love the unit, but I agree with “Shennings” Review that the backpack straps really need a chest strap to stabilize the unit on your back! I have had the unit for about 8 months and I feel like I am constantly having to reposition the straps as they creep off my shoulders.The straps might be perhaps a little far apart from each which making it hard to hold. A simple strap in between the shoulder straps would make it lot better. Although I am very pleased with the performance and power, I wish the unit weren’t so noisy. I feel like my neighbors must hate me whenever I am using it because of the db’s but I guess that’s what gives it the performance. The blower speeds up yard cleanup time TREMENDOUSLY for me and reduces the time that I am making all the noise, so I guess the shorter cleanup time makes up for the excess noise. The BR450 is a great unit and I do recommend it, but if there is ever a backpack strap upgrade then I would suggest getting it!

Rated 1 out of 5 by from This product is a great example of bad Engineering and Quality control! I have owned six Stihl products over the last 20 years. Until this purchase I have had nothing but praise. The BR 450 broke the third time I used the unit. It lasted 5 days before it had to go into the shop for repairs. It is hard to start and so noisy you have to wear double hearing protection. The shoulder strap padding is too short and does not give good support for the backpack unit. Very disappointed with the quality and functionality of the BR 450.

Rated 5 out of 5 by from Should have bought this one a long time ago Extreme upgrade from a hand-held blower. This thing is like a bulldozer. Moves piles of leaves, acorns twigs and small limbs. Good size on fuel tank. Not too heavy, controls are nicely laid out and adjustable to your comfort.What once took a half day with my hand held, rake etc. , can now be accomplished in about an hour just with the blower!The only thing that would make this blower better would be to have an adjustable chest strap that would help keep the shoulder straps in place and on my shoulders. Users with broad shoulders might not have this issue.

Rated 5 out of 5 by from Excellent Product is a time saver! Previously it took about 6 hours of raking and bagging leaves every weekend. Now it takes less than 90 minutes to clean up .39 acres of oak leaves and pine needles. Awesome power!

Rated 5 out of 5 by from Blower with attitude! Here I have been using these wimpy little hand blowers. This back pack blower means business! My lot in the city is almost 1 acre with lots of Pecan and Oak trees. This certainly takes care of business.

Rated 5 out of 5 by from Easy, powerful, comfortable blower. I have a 1/2 ac that is mostly cleared, but right next door my neighbor has a lot of Maple trees. As it is, the wind always blows from their direction and fills my yard with wet, heavy leaves. When my inferior blower finally quit working, I knew a Stihl backpack blower was in my future. I chose the 450 for its power and features. I really like the extendable Tube, as it makes putting it away super easy and takes up less space. When I’m working, if clears large piles quickly and effortlessly. It’s still new, but it starts in the first pull every time. I️ couldn’t be happier with my BR450.
