Rated 4.6 out of 5 by 167reviewers.
Rated 5 out of 5 by Great machine, very dependable I bought a FS 90r to replace my FS 55r. I use a brush blade and cut some fairly heavy brush. This machine always starts fast (usually on first pull) as it did new a few years ago and has good power. My only complaints are that the strap supplied with the the unit comes unhooked and I have to retighten the screws that hold the gear box and engine to the aluminum tube but not often, they just get a little misaligned is all. Other than that I would recommend this unit to anyone with heavy grass and light brush to cut on a budget. May 16, 2015
Rated 5 out of 5 by Excellent investment This trimmer works great. It is very powerful and starts right up every time. Haven't had any issues with it. This is one of the best trimmers that I have used. I love it. May 15, 2015
Rated 5 out of 5 by Amazing This thing starts easy and runs like a scolded dog. It has plenty of power. I love it! May 7, 2015
Rated 5 out of 5 by Workhorse I have owned two, one for 2 years, the other for 4 and now I need a new spool and line guides.This is the first time I have needed anything other than energy to cut more. I use them about 8 hours per weekend each. They last long under my abuse. A bit heavy but rock solid.Another great product! May 6, 2015
Rated 5 out of 5 by Easy to use has a great deal of power This has been an excellent buy. It is light weight with more then enough power. I have and will continue to recommend this trimmer to home owners and professionals alike. May 4, 2015
Rated 5 out of 5 by The Best Trimmer Hands down I work in parts and service at a power equipment dealer, we have many brands. After working there for a few years one thing became abundantly apparent to me the FS90R was the way to go. WOW it is an amazing trimmer, now I truly see why most of my commercial customers have them. May 4, 2015
Rated 5 out of 5 by Great trimmer for a moderately-sized yard I had considered buying the FS-56, but after considering the difference in the features, I went with the FS-90 R. The all-steel shaft was a major selling point. It is a little heavy, but it is a real workhorse. I have a brushcutter blade on it, and it cuts everything from grass and weeds to multiple rose bush to saplings. I would recommend it to anyone who has property that borders on a wooded areas. May 4, 2015
Rated 5 out of 5 by Powerful and versatile trimmer/bushhog I bought my FS90 R a month or so ago after comparing it to the other models they offer. After realizing that the FS90 R can take the brush blade as well as other attachments like a tiller head and pole saw, buying this model was an easy choice. The first day I used it I ran it for 6 hours with line and the blade around our property and went through 3.5 tanks of gas. I noticed a definite increase in power when starting the 3rd tank as well as smoothness due to it breaking in. Now that its broken in I think they should consider marketing this as a trimmer/bush hog. Its a hoss!With the blade on this thing it is unstoppable. Anything around .75" or under is zipped through just as quick and easy as grass. It starts on the first pull almost every time and is very powerful and extremely versatile thanks to its solid shaft and head options. I opted to buy the oil and double the warranty to 4 years, though I doubt ill need it. I expect this trimmer will last many years. Thanks for making quality products in the USA. April 27, 2015
