As far as I'm aware the bar mountings are the same for both saws .

 

The 039 was marketed at farmers , builders and firewood - original cutting equipment was a 10 tooth nose sprocket (smaller tip radius = less kickback) and RMC 3/8" chain (semi chisel round corner = stays sharper in dirty wood)

 

The 660 is a professional saw - original cutting equipment is a 11 tooth nose sprocket (larger tip radius = better boring and longer lasting) and RSC 3/8" chain (full chisel square corner = faster cutting)

 

So different bars and chains for different jobs:thumbup:

Thanks. The 039 was bought in 97. But had a new bar and chain put on last month. It's had a couple of uses but its not in need of a sharpen yet.

 

We run the 039 on full chisel now. I do with all chains. I prefer them for sharpening as I can see the edge and the corner.

 

I've got a 20" coming for the 660. But ive got to wait for it and it would be overkill for what it's cutting!
