Sharpening brush cutter blades

[nickw]

Anybody got any tips or how to videos on touching up or sharpening brush cutter blades. Bought one and it works great but the blade dulled quickly, not that I ever hit the dirt with it. Still knocks down the big weeds but the little wooden stalks less than an inch went down easy at first but not for long. I would imagine a flat file would help with the right technique

Pic of the teeth please. There are many styles of blades.

I ground the tri tired brush cutter blade I was using on my fs250r pretty sharp and it cut noticeably better and took a long time to dull. Even then it cut better than it did out of the box. I used a 4" Makita grinder on mine.

I sharpen my blade with a 7/32 chainsaw file. It is on a rs52e jonsereds.

Depending on style I sharpen to a 45 degree angle with a good flat file .

The blade is 8" 80 tooth echo blade

Those are a pita to sharpen, from what I understand. I much prefer the chainsawtooth style.

Agreed, especially for 1.5"+ dia wood.

Most definitely, and you can get 9" chainsaw-cutter blades for $15 from Forester. Total no-brainer.

For mostly smaller-stuff, I might use a 20-tooth 10" carbide (got a few to use up, can't sharpen-no diamond wheel), or 11" or 12" Husqvarna steel blades. Those 3- or 4-knife Husqy blades are DANGEROUS to woody stems up to 1.5", made of some tough steel such that I had to buy a 4" angle grinder to put an initial edge on them. Damn lawyers! Once they have a proper edge, most touch-ups can be managed w/flat-bastard.

I put lots of hours of use on all the above, using 21-27 cc brushcutters, clearing many acres of multiflora/privet/barberry/euonymus/porcelain berry and other rank invasives. They end up pureed on the ground for mulch.

Used to use those 80-tooth steel blades back in the day, like for woodlot mgmt. Only other choice was 8-knife blades, like for grass. Currently available blades give you lots more options, and hugely better performance, IMO.

For best pricing, consult Amazon or Forester. Dealer if time presses. Of course, Spike60 gives great prices too.

I sharpened mine and it worked much better on my fs250r and the huge one on the fs550 I had.
