MS170 Bails Out the 500i on the Hemlock, plus Dragging Wood with a Hi Lift Jack. Whee!!

Like the title says, we are back on the hemlock. We got the overhead piece on the ground and skidded to the path where a tractor can get hold of it. Then we go back to the big chunk and get it limbed up for bucking... but then the 500i throws the chain and we have to finish up with the MS170.
I was unable to repair the chain in the woods. Back at the house, the damage (burs) to the drive links were to too gnarly and numerous to fix with a file. I had to bust out the China Freight Foredom knock-off and a sanding drum to get the burs cleaned up. The 500i is back in action, but that was a pain in the buttocks.
