Hi all. I have a friend with a 575 baler. Baled hay and clover this year worked just fine. Started baling Ry grass straw and it is packing too tight, can hardly push out the bales. Backed off hydraulic cylinder and side plates, bales real tight and about 65lbs. Cleaned out chamber and can see no problem any suggestions welcome. By the way over ride clutch hot and braking shear bolts. thanks
