Good video
I bought one of these in 2018 with a few different attachments. IMO Stihl has the best quality attachments out there.

I have run a pair of KM130's on a trimmer head and pole saw for about 8 years now. They are HAMMERS. The trimmer uses the alloy FIXCUT 31-2 spool head loaded with 0.170" string. ALL of the auto advance heads (and strings) I tried welded the string internally to the spool when the air temp was over 85F or so. The FIXCUT is stone axe enough it works at any ambient. A string charge will run 15 minutes (rocks) to maybe 2 hours (tall dry grass). The pole saw (old model) uses much the same hardware as the extensible commercial model. It accepts 14" & 16" blades & chains and has cut every stick of firewood (3" sticks to 16" discs, mostly oak) I use for the past 8 years. The KM130 pair allows you to go about your business if you develop engine issues, mostly a plugged carb or fouled plug. I also have the 40" extension, useful on a hillside with the trimmer or for cleaning up low "ladder fuel" branches. The Kombi Tool is the best money a rural homeowner will spend.

I've had a Kombi KM131 for about 5 years now  with a power scythe, articulated hedge trimmer and string trimmer attachment. I also have the FS 131 that i use with a chisel tooth brush cutting blade for cutting scrub oak and manzanita. Both are excellent tools and and it's saved me an enormous amount of work. They always start with just one or two pulls on the rope. I also have a chainsaw, an MS271 Wood Boss that just sat for over two years without starting. I was beginning to dread trying to start it  because  I thought would be fiddling with it for a few hours. Six pulls on the starter rope and fired right up; old gas and all! Amazing equipment.

Had mine for 6-7 years now and its a beast. Was using other brands before that and was always having issues...craftsman and other brands like that. Ended up going with Stihl for the first time and now I ended up buying 5 attachments.

Only issue I've ever had with the Kombi system was the hedge trimmer but it was a 1$ fix, a screw broke, which admittedly I was probably trying to cut something too big. Replaced the screw and still working great.

Anyone doing tree work or anything above shoulder height, trust me, get the lightest Comby system motor you can, it doesn’t take a lot of power to do tree work, but your arms and shoulders will tire out very quickly the heavier motor that you have

These combi systems are excellent, I nearly bought the 131 but opted for the Husqvarna 535LK for the extra power and lower price. Think the Stihl hedgecutter attachment is better, but the 535LK gives me 2.2 HP and can cope with almost anything! Do love Stihl equipment though, as it is excellent quality!

I figure it would cost me $400 more then an off brand to buy everything I want...but I will now have room to expand my yard tools.  And I have always had good luck with Stihl.

Two years on and my attachment won’t separate from the head. This is the second time; the first time was when it was brand new. Now the dealership can’t separate without full service ($$$). I have used this attachment less than 10 times. So much for German engineering!!

I have a handful of residential properties I look after and have been using the Combi system for the last 12 years or so and wish I'd had this years ago as it helps me get so much work done in a short time. Started off with the homeowner 56 but went to the more pro 94 a couple of years later- no comparison. The 94 is a 2-Mix engine (2 stroke) with stratified combustion and a lot more economical than the 56 and is a beautiful little engine. I recently upgraded the whole set (I have the line trimmer, pole saw, blower, edger, adj angle hedge trimmer, and carbon extension) and went with another 94 engine. The 91 and 131 are 4-Mix engines which are a premix 4 stroke with all the associated valve gear to maintain and extra weight, no thanks. The 94 is a lovely light little unit with adequate power for all those attachments I use. While I was disappointed after upgrading that Stihl had shortened the hedge trimmer the light weight of the 94 and my love of that blower which has a million uses kept me with the Stihl Combi system.

Best purchase of my life. Awesome equipment 👍

Great Job!! Answered all my questions.

Great overview of the tools and cost considerations.

Very informative!!! Thanks

Thanks for this video, well explained.  I learned a lot.

Very helpful.   Thank you.

kombi system is great, we are using 131r for professional work. another good reason to get kombi system is because when dissasembled its small, can fit in a car easily

Thanks for explaining the attachments.  Buying just the end and not the whole pole sounds cheaper.

In Germany it's called the Kombi motor

I love the Kombi. I made the mistake of getting the original battery power head. The 135R is great.
