Patz 98b. The stories I could tell. We ran one until it was absolutely, totally, 100% wore out. 

And then we tore down the silo.  

The last two seasons were no fun, trying to get the last life out of the old Patz. Feeding with one guy in the silo about 75% of the time, I can still probably replace a chain link at 20 below in the dark, its a skill that never leaves you. haha

Not a bad unloader if you have enough sense to replace it when it is done.
