We have temporarily paused production due to a manufacturing tolerance issue. The issue caused chain kerf to be slightly narrower than other chain on the market so that on bars that were worn there was a bar pinching issue. 

We are currently testing the new chain design and it looks like we have this fixed but we want to be very thorough in this testing process so it could still be late summer or the fall before we get production back on line.

Harvester chain that stays sharp and increases your production

Made in USA

How much production are you losing because your harvester chain dulls too fast?

Dull chain slows you down and causes you to loose production. Don't be held back by your harvester chain.

  • Cut logs piled viewed from the end of the logs with growth rings clearly visible.


    You will produce more timber because you will spend more time running a sharp chain.

  • An old fashioned alarm clock sitting on hundred dollar bills.


    You will spend less time and money changing and sharpening dull harvester chains.

  • Pi Harvester Chain loop laying on flat surface.


    You will buy less chain because because of slower tooth wear and longer chassis life.
