KM 94 R

KM 94 R
A professional-grade multi-task tool with lightweight ergonomics and ECOSPEED-enhanced efficiency.

Product Description

The 2-stroke KM 94 R KombiMotor, combined with any of 14 optional tools, offers landscape professionals an efficient multi-task system to meet the versatile needs of their clients’ yards. The lightest weight model in the STIHL KombiSystem line-up, the KM 94 R weighs in at a mere 8.8 lbs. The ergonomic loop handle, coupled with an excellent power-to-weight ratio, delivers the maneuverability to navigate obstacles while helping reduce user fatigue. The multi-task concept provides convenience and efficiency through reduced maintenance and storage – one engine for many tools and tasks.* The innovative ECOSPEED throttle set wheel allows the user to set the most effective throttle speed for a particular job and attachment. Now it’s even easier to love the space-saving, cost-saving STIHL KombiSystem.

The STIHL KombiSystem is a versatile landscaping system that includes a powerful STIHL KombiMotor and a full line of attachments. Together, they give landscaping professionals the ability to tackle a tremendous range of outdoor tasks without loading the trailer with a pile of tools. Attachments include trimmers, blowers, hedge trimmers, edgers, pruners, cultivators and more. Each attachment slides into the KombiMotor effortlessly and is secured via a quick-release coupling system, saving you time as well as trailer space.

NOTE: STIHL KombiMotors and STIHL KombiSystem attachments are sold separately.

Rated 5 out of 5 by from Light weight but powerful. I like the power in addition to the light weight. Starts easily and runs smoothly. Has a high-quality feel.

Rated 5 out of 5 by from best bang for your buck I have had my KM 94r for about a month now, and I love it. Only gives me problems trying to get it to cold start but after working at it for a little while I can get it going.

Rated 5 out of 5 by from Great So Far! I bought this to augment a similarly displaced string trimmer from another well-regarded company after an extremely positive experience with the BR600 backpack blower. Grew up the son of a high-end residential landscape designer / contractor and really enjoy doing my own yardwork. I'm currently running pole saw, articulating hedge trimmer, and straight shaft edger. The pole saw does well overall; it can bind a little in the thicker stuff, but for most applications the power to weight balance is ideal. I imagine this advantage would really shine with the extension. The hedge trimmer is perfectly powered and well balanced. If your main use would be that attachment this is absolutely the right power head. The edger is great once you get a trench defined, but does require a little finesse and patience if you have some particularly unruly areas. Give it a little each week for a month and you'll have a great looking trench edge to shame the neighbors. Again, for my regular use I don't think more power would be a long term advantage. I have not tried the bed redefiner, but am suspicious this would be serviceable. If you plan to use that attachment extensively you might be better served with a larger displacement unit. I'm a little reticent to give up my dedicated string trimmer based on some of the reviews of that attachment, but may still give it a whirl since a lot of folks seem to ask more of that tool than it was intended for. I run premixed "white gas" in all of my two cycles and have had no issues. I've been pleased with fuel economy. Starts, attachment swaps, and general use are essentially zero fuss. As an involved homeowner my savings over hiring occasional help for some jobs have already paid for the expense of this unit in about 3 months. This is a good product and I'd happily recommend it to a friend.

Rated 5 out of 5 by from Lightweight power Im a professional trail builder, so when I choose a power tool I'm looking for the optimal balance of power and weight. Often walking miles through dense brush and steep terrain, I can't afford to lug around extra weight. I have cleared miles of 1-2" autumn olive, brush, branches, vines, and understory growth with the adjustable hedge trimmer, an absolute beast. This unit checks all the boxes. Reliable, powerful, lightweight 2 cycle power. The extensive positive reviews sealed the deal for me. Use an ethanol free pre-mix fuel and it will start easy for life.

Rated 5 out of 5 by from Should have bought sooner I've only had the unit about a month now but I regret not buying it when they first came out. It has more than enough power for trimming and doesn't bog in the big stuff. I've used FS-90s professionally and this feels like it has just as much power but in a light weight two stroke. It handles the blower attachment and pole saw very good too. The 94 needs about 2-3 minutes to get warmed up and get to full power but once it does, it's an absolute beast.It seems to be extremely fuel efficient too. Time will tell how it holds up but my experience with Stihl products has been nothing but excellent.

Rated 5 out of 5 by from Best Kombi I've Owned The KM 94 R is by far the best Kombi I've owned. This is my third one I purchased and compared to the other two it is by far the best. There is always enough power for any of the 6 attachments I have. It is very fuel efficient and easy to start. I like its light weight, especially when using the chainsaw attachment. The Stihl Kombi is a little more expensive than other brands, but as the saying goes you get what you pay for and is certainly true in this case.

Rated 4 out of 5 by from Quality plus! I love how this engine starts an runs as it was designed. It's too soon to tell if the cost makes sense, but so far the power and quality of manufacturing are top notch. As it turns out,the power unit is somewhat compatible with other manufacturers end tools even though the quality may not be the same. I will use them up and replace with Stihl as needed.
