I'm kinda new to this forum so i might be posting in the wrong place.. Sorry if i am. I've owned this baler for a little over 20 years now, its a vermeer 504g and for what ever reason when i try to turn with the baler running the #80 chain that runs the belts that form the bale(Can't remember the name of them) starts slapping around like its loose and hitting on the door but when i stop mid turn and check the chain is very tight and it stops when i'm baling in a straight line. the people at the vermeer dealer think something is coming out of alignment when i turn or the frame is cracked but i can't see anything like that. Anyone got any ideas?
