Ben, Don't know anything about this specific baler, but I am assuming that it is a small square baler. I think you were referring to the "plunger" that goes back and forth to compress the hay. The way I have unstuck one is first power wash the chamber real well. Then soak it top and bottom along the rails with a good penetrating oil. After a while, I started rocking the fly wheel by hand back and forth and kept pooring the penetrating oil to her. I did this with a JD 346 that sat in a field for about 7 years with hay in the chamber. I also have experience with a newer model NH 570 that sat for about 2 years. It was not stuck, but stiff, and the first time I baled with it the rails (metal plates that the bearings etc ride on) got very hot...called it quits before I burned it to the ground. Long story short, the rust built up underneath the rails (between the rails, shims and bale cavity) and caused the plunger to fit way too tight. Once you get it unstuck, you will probably want to pull the plunger (yes, all the way out the back of the cavity using a chain and come along) to inpect the bearings etc. and to sharpen the knives. Be very careful working near the knives with the plunger installed...if you get it moving very smooth, and the arm is overcenter, the plunger could move backward if you bumped the machine and there goes a few fingers... Good Luck, Tim
