I meant the Oregon Powersharp chains to accompany all the root cuts you are doing, as a result of using the AM.
Obviously a POS compared to a $800 Silvey grinder (which is portable, but way heavier), but compared to filing by hand...

I run all Stihl chain, which is harder steel, and harder files. From what I read here, when you rock your chain, it screws up the steel, 'work-hardened' IIRC. Work-hardened steel or chrome, whichever, is hard to file. A grinder will go through it.
I didn't set up my grinder in the last year or year and a half, since I moved from my old house. Did a lot of root pruning. I bought files for my MS261 at the Husky dealer. Not hard enough steel. Wouldn't do it. Grinder didn't care. For real cutting, they need more fine-tuning with a file, but most groundies wouldn't know the difference.
Dirty cut after dirty cut... a couple chains in rotation on the grinder while the other guy is cutting.
With all the street/ sidewalk trees you guys are up against, I think getting away from hand-filing would be good, especially with the wear-and-tear of the AM on wrists.
A silvey is just bolted to the stand. It could as easily be bolted to a 2x4/4x4, and clamped into a vice on the chipper or screwed to a tall enough stump.
