I really like mine

Just bought one of these. Fantastic video of the basics to get you started. Thanks for sharing your knowledge and experience.

Love the newer 26-2 heads for reloading. Genius way of reloading, love it!!!!!

I have had an FS91r for years, usually using the string head and the metal blade (when its wet enough out to not worry about fires). I have a polycut head for it that has some german writing on it and in english it says "Grassbuster". Its been a while since I've used it, and I can't find the manual for the head. I went to put new stihl polycut blades on it and it is nothing like any of the videos I can find. Every video I see for similar heads on a Stihl just have the polycut blades sitting very loosely on the bolt. My old polycut blades that are still in the grassbuster head have metal bushings pressed into them; the bolt goes through the lower half of the head, then through the bushing in the blade, then there is a "threaded washer" on the bolt, and finally it goes into the retained nuts on the upper half of the head. So I had to tap the bushings out of the old blades using a large socket underneath and a smaller socket on top. Of course the bushings won't press into the new blades easily. I tried tapping them in but they are impossible to get in. So I was able to get the bushings seated into the new blades by assembling everything in the right order and tightening the head together which got the bushings seated in. I then had to take the head apart, and tap each bushing in further with a hammer. Now when I put it together, the threaded washers can thread all the way down the bolt until they drop off the threads and just float on the bolt shaft next to the bushing/blade. I am not going to spin this thing up with these washers rattling around loose on the bolts inside the head. Why did a Stihl dealer sell me this head which makes replacing polycuts nearly impossible when every head I see online, you just open the head up and drop new blades onto the bolts?

Just bought mine yesterday. Love it so far

Just bought one of these last week for my lawn business to run alongside my 94r I love them both. 91r has great power for the size and the extra weight doesn't seem to be an issue

Just bought this model, love it

Another great video, keep up the great work Josh!

Excellent video. I appreciate your easy to follow presentation. Your verbal skills are engaging

Very nice video. Thank you. I am repairing 2 of these that are owned by my neighbor. "They don't run worth a XXXX!" PROBLEM: He leaves them on his trailer and they get rained on. A lot. Less than 2 years old and every part that can rust, has rusted. Yes, the air filters were soaked with water and indeed, they were growing MOLD. I have NEVER seen that before. I cleaned them up and replaced air filters. Absolutely awesome machines. I wish the idiot would take care of his equipment. -- North Central Florida

Good video. Just bought one of these with the larger handles and three bladed cutting head. The shop didn't ha e the correct (25-2) autocut head but I used instead a 36-2 head. Seems okay but probably not as light and responsive as it could otherwise be. I hope my choice of head isn't going to cause any other issues.

Remember too all 4 mix carburetors have a accelerator pump so never hold the throttle open or pump the trigger you will flood the engine 😁

so the fs91r vs the km91r... are they they same specs other than the km being a kombi unit?

Those little bottles I got say they make 2 gallons. They look like the same ones you’ve got.

Great video!!! I just bought one of these and used it for the first time today. However, there was a problem. The bump head would not let any more line out. So, I removed the cover and discovered that the line was overlapping itself on each spool, preventing any line from being released. It appeared to be intentionally done by the manufacturer.

I’m sorry about that experience, we try to always make it a habit to rewind all of the heads on the machines we sell as we found it an opportunity to eliminate any bad experiences like you may have had. If you need assistance with the rewinding of the head we’ve got a great video on that.

I have that same unit, and i always use 93 octane gas with Stihl HP ultra oil. Is okay to use .105 line??

You can add gearbox attachments.

Can you feather the trigger on the FS91 like you can on the FS94? In the past, the 4 mix units were all of nothing. Sometimes, you just need a small amount of power such as when you're around flowerbeds. I'm trying to decided between the FS94 or FS91. Thanks

Thanks for the tip. So, would you recommend the 91r over the 94r. They're both the same price ($479 Canadian) where I live. I did find a pretty good used 94r with about 10 hours on it for $380. There's no warranty left on it and the owner can't find the bill of sale but it does look like it's in great shape. Not sure if it would make more sense to go that route to save some dollars.

Oh yeah...by the way, I can wear down a plastic bump head in about month and a half. It is impossible at some of the places I cut to avoid running it over buried/partially exposed lava rocks/boulders down to the small lava cinder bits. The metal disc that you load two strings manually is the best for longevity, but not speed🙄. The brush blade is BAAAAD to the BONE!! Can't work without Stihl Products!!!

If you can find a grass patch tap more string on the grass or even dirt. Your cutting heads will last alot longer. Concrete, rock and blacktop is like taking a grinder to it.

What’s the purpose of the black plastic sleeve betwixt the grip and throttle? I want to remove mine to gain more adjustment out of the handle.

What?! Four stroke? I've been out of the game too long 🤣

The handle was not made correctly. You have a hard time tightening the handle into position because the "loop" blocks the screws. Further, the nuts holding the screws are square when they should have been hex locking nuts. Design oversight that even I can see.

It is but still uses the gas oil mix to lube the necessary components that a four stroke possesses

At the first of the video you said it was a 2 stroke then halfway through you said it was 4 stroke...?????

IMHO Lucas oil is way better than Stihl oil in Stihl products. I'm not the only one who believes this. My BR600 blower and FS 91 trimmer have more HP when using other than Stihl oil.

Buy a two stroke...i have two of these 91's very lil power compared to my two stroke stihls.They are 4 stroke mix lol...might be ok for a home owner with a lil neighborhood lawn...but for serious work and tall grass there a joke...your constantly listening to it blubber in the rev limiter.All mine need is a big trash can...my fault got suckered into trying the new 4 strokes...should have known better
