check my response to jack. I had the exact problem with my green 24T. It got progressively worse to the point that every time the tie lever fell (initiating the tie cycle) the pin would shear. He said that's no problem. Your brake is not working. Went home and inspected the brake and the pads were gone (like worn plumb out). Went to the deere house and got a new set ($50 but worth it), installed them and problem disappeared. Did not have to touch timing. As jack said, the knife protector shield pops up and the bale plunger smacks it and that is the step function that shears your pin. Proper tension is to have the baler in the pack hay config (not tie) and trip the activator wheel. This wheel is driven by a shaft that comes up from the needle assy. Just push it forward (abruptly, about 3")by grasping the shaft where it connects to the wheel, and rock the wheel (to which the shaft is attached...about 6"in dia on opposite side of baler from brake on the deere) back and forth. This shaft also turns the rotor of your braking system. Proper tension on the springs of the brake shoes is such that you feel pretty good resistance to your rocking effort; not tight but you can feel resistance as you rock the wheel back and forth. I'd define that as half way between won't move and no resistance.(on mine there is about 3/8 inch of thread sticking out past the nut that tightens against the spring that tightens against the pads. When finished, just pull the shaft you initially pushed forward back to it's original position (back 3") and you are ready to go. Nothing but the wheel, the brake disc and interconnecting rod, should turn during this process. No pto movement or anything else. Mark
