    Chainsaw Cutting Chains

    This morning I observed a professional tree lopper attacking his chainsaws with an angle grinder. I thought he was sharpening the cutters or grinding the depth gauges down but on closer investigation he was completely removing every second set of cutters.

    He claimed, and subsequent observation confirmed that it reduced the drag and enabled faster cutting.

    Just wondering if anyone else has seen/heard or tried this technique?

    Here's a photo of the modified chain.

    WOW......probably work well on green timber. I wonder if it works just as well on dry/seasoned timber?

    I think it will depend on what you are cutting. I can't imagine it doing well on my seasoned ironbark!

    As mentioned, it's a skip chain - used by loggers, etc who cut green timber all day - it clears the chips out of the chain better and makes for faster cutting - in green timber only. Used to live next to a group of loggers, all their chains were like that.

    It will cut dried wood, but not as effectively as a normal chain.

    I had heard of skip chains with an extra link between cutters but this ended up with five links between cutters!

    It definitely does not cut faster it's purpose is less load on the power head in big timber when running big bars 42 to 72" when used on 18 to 24" it's slow and vibrates like a bastard. A full comp chain will cut faster in just about every situation if you want to cut green timber fast use square ground chain and learn how to sharpen it

    That's different to what I observed - This was used on a 20" bar at high speed and cut through the green hardwood very fast, including when ripping the larger logs.
    Comp chains may be faster but this was being used by a professional tree lopper in an everyday working situation.

    A full comp chain will still be faster. Another plus for skip is its faster to sharpen having less cutters and all. A good example of how fast a good square chain can cut this is a 50cc bread slicer with 18" bar in some dry hardwood it would double its score in green timber Rancher50 nitro 2 - YouTube
