Stihl MS391

Recommended Posts

Anyone know what’s the biggest bar compatible with this model? I’ve got a one off job needing 36 inch 

i am looking at a rotatech 36’’ one for a Stihl 056 which might fit or would the bar mounts need altering?

I know it would be slight underpowered but only need to make about 7 cuts and don’t have a need for chains this big

Yes it’s a 15ft oak stump not far off 6ft diameter.think I may struggle with 20’’ but it’s hard to tell how rotten it is inside before doing any cutting.i reckon it was cut and left at 7-10 years ago

Perhaps you should do a test plunge cut to see how solid (or hollow) it is , a short bar may well do the job if  hollow.

I have a Stihl 039 with a 25" bar running full complement chain. It's just powerful enough but I still wish I'd bought a skip chain. I wouldn't consider running full comp on a 36" bar with it but I would consider doing so with skip. I'd try to get away with a shorter bar before that though. I wouldn't buy inferior cutting equipment whatever. My 25" bar and chains are Stihl. I bought quality (and new) knowing I can put them on a bigger saw when one comes along.
