A few weeks ago, I swept out the garage before moving my John Deere 4110 into it's winter location. So at that time, the garage floor was clean. I used the tractor several times over the last weeks and it has been the only machine parked in this place. Yesterday, I noticed this chain on the floor underneath the engine area. It looks like a small bicycle chain about 12.5 inches long, but the link size is much smaller. On one end, it has a vinyl coated wire hook, about the gauge of a paper clip, but the bends don't line up with a paper clip and besides, it appears to be very light duty, so I doubt it is a operational part. But, I don't remember seeing this before in the 10+ years of being in the house! Is it from the tractor?
Any ideas?
