In this B7500 diary, I'll introduce Old dog w/2500hours, beat up but runs once it starts. I know! I know! but below 70* the first start takes a puff of - - - - ! I just recently acquired another B7500 that starts like a dream. It came with 540hours and just testing, even at 50* it will start without GP but takes 30 seconds longer cranking. This newest addition has no FEL and as soon as I get my courage up I want to swap the one off the old dog. It has the lA272 fel which is a quick dismount. But I've never had it off in 10 years! I haven't done a intensive search yet but wonder about the hydraulic ports on this newer (2004) machine. No manuals or info to direct me.
