Increased Edge Retention and Durability

All comparative testing used Oregon®­ 11H 3/4" pitch harvester chain. 

Edge retention

    Pi harvester chain has consistently cut twice as long as Oregon®­ 11H when testing in the field. Pi harvester chain's high edge retention is a result of a patent pending cutter edge design. Keep in mind that after hitting something like a rock Pi harvester chain needs to be resharpened like any other chain. 

    Chain life

    Pi harvester chain has a tougher chassis and harder rivets than conventional chain. This results in Pi harvester fewer breakdowns and repairs compared to Oregon®­ 11H as observed in field testing. The chain chassis is tough thanks to 100% American made steel and specialized heat treat to deliver you the most durable chain we can make.
