How do I tell whether my saw takes a narrow kerf chain?

[somanytrees]

I have a 10+ year old Husqvarna 435 x-torq with a 16" bar (oem replacement of the original bar), and I'm looking to order some chains online, but I'm confused about whether I should be ordering a narrow kerf chain for this machine.

Also, does anyone have a recommendation for something that cuts a bit more aggressively than the stock chain?

Post a pic of your bar numbers. That will help us.

A pic of your current chain, too.

That's exactly the information I needed - the paint has been scraped away so it was not obvious, but thanks to your photo I knew where to look.

Thanks!
