Guess what happened here:


Larger view:


I have a theory, but I want to hear what you guys come up with first.
You can kinda see it in the 2nd picture, not all the holes have the marks on them. The marks are in two sets, not quite 180 deg from each other around the disc.
All holes are evenly spaced and are supposed to be there. The marks around the holes are not supposed to be there.

Bonus points if you know what it came off of.
Double bonus if you know the model.
Triple bonus if you know what size.

Actually, the large radial marks coaxial with the center of the disc are from normal wear. See below.

This, but for a IH
Bingo!!!!!!


Does it have to do with cotton?:eek:
It could. Just probably not with those seed discs. The holes are too small and too many of them.



Actually it's our theory in the office that these discs were left in the seed meter over the winter and a mouse/rat got in and gnawed on all the holes they could reach. The area they couldn't reach was the vacuum blockoff area of the seed meter cover.
Those discs were actually sent to us by a field rep. He was completely confused by them. We were too until we realized that the chewed holes lined up perfectly with the vacuum passage.

The large marks are actually wear marks from the seed meter cover. The seed is picked up when the seed disc passes by the seed in the bottom of the hopper because we draw a vacuum on the opposite side. the seed is carried up through the singulators ( to knock off any extra seeds, so we only plant them one at a time), and then over the seed tube. The vacuum blockoff on the meter cover causes the air pressure to equalize on both sides of the seed when the disc rotates that far, and the seed drops off the disc, through the seed tube, and into the ground.
To maintain the best vacuum stability possible, the meter cover and the seed disc are both made of a special plastic. They both are considered wear items because they are designed to wear in together to get the best seal possible. It usually takes several years to wear out a seed disc and a cover.

I am going to say a Christmas Tree harvester. Part of the tree plucking aparatus that goes round and round. Someone didnt tighten the bolts up well and they spun around with their washers.
