    More information

  • Purge Pump Primer
    A small fuel pump delivers fuel to the carburetor when pushed, reducing the number of starting strokes required following extended breaks in operation.
  • Loop Handle
    The loop handle (R) is an adjustable rounded handle mounted on the shaft for support and control. The handle is designed to help control the machine in different positions, ideal for reaching tough spots. The handle is large enough to accommodate a gloved hand comfortably.
  • Quick-Release Coupling
    The quick-release coupling system makes it easy to switch between Kombi attachments. In addition, this feature allows KombiSystem equipment to be dismantled into two parts for easy transport and storage and then re-assembled quickly without tools.

  • Anti-Vibration System
    STIHL has a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.

  • Electronic Ignition Module
    The electronic ignition provides reliable starting and because it is fully enclosed, it is protected from moisture and debris for longer service life.
  • Multi-Function Control Handle
    Having easy access to all of the controls on one comfortable handle help makes it easier to complete tasks so the operator’s hand never has to leave the handle.

Rated 5 out of 5 by from Awesome machine I have only used the straight shaft weed eater head so far but it has not let me down. I used it in two foot tall grass with .095 quiet line and it knocked it right down without a grunt. I tried it in some goldenrod about 18 inches tall and it mowed it right down but the .095 line didn't last long. I put some .105 square line in and tried that and what a difference, it even cut some small new growth on bushes and up to about 3/8in pricker bushes. I have probably only put three hours on this machine but I can say I'm very impressed so far. Well worth the money!

Rated 5 out of 5 by from Another great tool I bought my first Stihl product over 6 years ago and haven't looked back. I'm on my fourth purchase with the Kombi tool and nothing has changed with quality, function or performance. I pay more today but I'll have my tools for years down the road, it's then when the value is fully realized. Go cheap and you'll spend time working on the tool, buy Stihl and you'll get your work done!

Rated 5 out of 5 by from Awesome weed eater! This weed eater is far superior than my last one (although they are okay for someone with small amounts of weed whacking in urban flat areas). This unit helps me get my weed eating done in half the time because it's longer so I can cover more ground and has a more powerful engine. Not that it makes a whole lot of difference but it even warms up in half the time. I really like the attachment system which is something I liked about my old one. The strap that attaches to the weed eater is really cool and something I've never had before. So far I don't have any negative things to say about it.

Rated 5 out of 5 by from Awesome product Starts right up every time, will idle all day long.. even upside down. Has more then enough power, never bogs down no matter how thick the brush. Easy to change attachments... would recommend to every one.

Rated 5 out of 5 by from Awesome Product I purchased the KM 90 R about 4 years ago and it is still running strong. This is a very reliable piece of equipment with minimal maintenance that needs to be done for it. I bought this to replace a Home Depot product that did not hold up. This gets a good deal of usage and I have a large selection of add-ons for it. Best lawn equipment purchase decision I have made in a long time.
