Im thinking of upgrading the factory Husquvarna 18" bar on my 562XP to a Powermatch 20"with a Stihl chain. I cut 95% of my firewood off the pile. Typical diameter of my current batch is probably about 10" on average Im going to get a new chain regardless if I stay with the 18 or go to the 20 because I hate Oregon's chains and usually only run Stihl. The factory bar that came with my saw is a bit of a POS. I call it the Pinchmaster 9000. . Its a non-replaceable rollertip that is held together with very tiny rivets. The slightest pinch and the chain grove closes up. Sometimes so tight that I have to pull the chain and re-spread the groove with a screwdriver. Honestly its one of the worst bars Ive ever used when it comes to that. Frankly I expected better. I think is's an Oregon bar but I dont know which model. I thought the pro-saws came with Husquvarna branded Powermatch's? Ive never had a PowerMatch jam up like this thing. Ill snap a pic tomorrow of the bar. So 18" or 20"????
