FSA 90 R

FSA 90 R
Professional straight-shaft trimmer powered by a 36-volt Lithium-Ion battery for excellent cutting performance. 

Product Description

The FSA 90 R trimmer combines the benefits of Lithium-Ion technology with the renowned power of STIHL. A quiet, battery-powered trimmer, the FSA 90 R is great for landscaping in noise-sensitive areas like school grounds, business districts or hospitals. If it’s ease of use you’re looking for, this is the trimmer you need – it’s lightweight, has a 15” cutting width, ergonomic loop handle, a slim profile for easy handling and transport, and starts instantly with a squeeze of the trigger. Additional benefits include the innovative control handle with ECOSPEED “soft” stop trigger setting, which can extend the amount of work done on a single charge. The time for trimming fuel costs and exhaust emissions is now, and the FSA 90 R is the right tool for the job.


Run time may vary based on battery type, charge level and capacity, model, operating style and conditions. Batteries and chargers can be purchased separately or as a combined set with tool.

Reviews

FSA 90 R is rated 4.2 out of 5 by 26.
Rated 3 out of 5 by from Great brand, good power, easy to use, poor balance Let me start off by saying I purchase all of my landscaping equipment from (excluding mowers bc they don’t make mowers) Stihl. Love the brand, the customer service, literally everything about the company. Which is why I bought the FSA 90R no questions asked. However when I receive the product (two days ago) I was immediately disappointed. Stihl, you’ve been making these products for years why did you change the weight distribution of the machine? All of the weight is in the head of the trimmer. For those of you who use weedeaters all the time you understand the importance of the balance of the machine. I’ve been Landscaping for 18 years, this will be my FIRST Stihl product that I will have to sell (at a loss).

Rated 4 out of 5 by from much better performance than my gas powered (former) trimmer I have had the FSA 90 R now for two seasons and I am so glad I made the purchase. I used to have to fill my gas-powered trimmer twice to complete the job that I can now complete with a single battery (and still have power left over to put the battery in my blower) I don't have to worry about scalding my arm or smelling like gas either. I was skeptical at first about the power of a battery-powered trimmer, but this tool performs better than the gas-powered did, hands down. I wish Stihl would come out with a stand-alone battery-powered straight edger now. I don't want to buy the multi-tool. I use this for residential use only. If you can afford it, go with this model and you won't be disappointed.

Rated 4 out of 5 by from Great Product With Limitations Pros Reliable - runs when you put charged battery inAdjustable throttle - at low speed, you can do grass lines, up against fences, etc ... with no string break and perfect trimming around delicate flower beds and trees. Excellent finesse. Low throttle dramatically extends battery life per useIt’s quiet It’s powerfulComes with thick string that doesn’t break easy on low throttle and trims beautifully ConsBattery life - don’t get me wrong. The battery life is decent for trimming a large city lawn - on low throttle - which is all you need. But if it’s more - brush etc... - this won’t work due to brush draining battery life Balance - it’s a bit unbalanced due to heavy motor in trimming end vs light weight battery end but you get used to that quickly Not as fun to use as gas machine. I love to hot rod a gas machine. Just feels good. Purchase again? I probably would due to three factors - it’s quiet, it’s works when you put battery in, and it has perfect power on low throttle for finesse work on all lawn chores.

Rated 5 out of 5 by from Far better than I hoped. I had hoped to be able to trim along my 300 for chain link and 100 white picket at least once before charging. I have done that four times plus more and have yet to charge the battery once! It is plenty powerful enough and the string dispenser works better than and weed eater I have own; both gas and electric.

Rated 5 out of 5 by from Very impressed with the trimmer I was finally able to mow my entire yard between rainy days. I was able to do all of my trimming on one charge of the battery. I loved being able to walk around without having to use hearing protection. Now that I have invested in a battery and charger, I will be purchasing additional batteries powered tools.

Rated 5 out of 5 by from Equal to the gas powered machines The FSA 90r is powerful enough to compare with gas powered trimmers while being lighter and easy to handle. It cuts grass at much less than max power so the battery lasts a long time. There is none of the extra work and mess of gasoline engines because it starts with just a sqeeze of the handle.

Rated 5 out of 5 by from Great Trimmer Love everything about this trimmer other than the fact that the battery is hard get out. I really like the governor control it has. Great to trimming around beds at a slower speed.

Rated 5 out of 5 by from Aweome Makes professional yard care look easy. Its quiet and efficient. A little heavy on the head when using the battery pack. Nothing to off set the weight of the head
