IH #37 wheel disc with pics

I picked up this disc the other day. I believe it's a IH #37 disc? It's an 8 footer which is hard to come by around here. Lot's of 10-12'+.
It has the newer bearing some with grease zerks and some without.

Any idea what years this was made?

What do you suppose the plates welded on each side are for? I suspect that was a farmer ad on?? or is it factory?

It's heavily reinforced with 3"x1/4" channel iron. I suspect to add weight as it doesn't seem to be worn out or broken/repaired.

It is a 37 , and a nice one , the plates on the rear are most likely to pull a harrow to break clods and level the ground.
 
The weak point of those models were the latch that held the base end of the cylinder. When you put the transport safety pin in and then go to retract the cylinder there wasn't much play in the latch and it would just pull the latch apart or stretch it. I removed the little latch and put a slotted metal bar in mine which made it possible to retract the cylinder completely while the disk was locked in transport mode. I also a got a patent on it.


Follow this link and it will take you right to it. I drew my own drawings and they added the numbers to the parts. A couple of the drawings show the slotted bar real good at the base end of the hydraulic cylinder. I stayed home from work 2 days to make those drawings. I drew all the stationary parts first, had copies made then added the moving parts such as my bar I invented, the axles and the wheels, cylinder. The slotted bar also allowed the wheels to float over the contour of the soil with out raising the disk out of the ground. That is also illustrated in one of my drawings. Looking back, making the drawings and explaining all of it to a patent attorney was the fun part. Luckily I had an attorney that grew up on a farm and he completely understood my invention. It cost me $5,000 back in 1991 to get the patent. It was just something I always wanted to do.
My Patent
 
It has 3 draw bar looking hitch points that I think are exactly what you say, a place to hook a drag to. Left, center and right.

I want to know what the ramp looking plates in between are for?

John, I know what your mean about breaking the latch on a 37 disk. I broke at least two of them by hooking up the hoses backwards. Finally put a black tape on the "up" hose and a black mark on the tractor so not make that mistake. But you still have to make sure you don't try to lower the disk in the transport position. It wasn't until I started using it on a newer tractor as the hydraulics on my MD and 400 were not strong enough to break the latch. I also have a 370 disk and that latch is almost the same. But someone welded mine up to make it much heavier so those must break too.

I also have one patent but that was paid for by AT&T. So I have a feel what you had to go through to obtain a patent on your own. Always nice to have a patent.

Maybe to hold up whatever they were dragging while transporting from feild to feild ? I have a 12' model that has similar brackets , but don't have any idea as to what they did , I never remember using them for anything .
 
Around here a lot of farmers would cut an old telephone pole or tree of similar size and hook it with chains crossways behind the disc, to smoothen out the ridges. When transporting, they would simply lift the pole up by hand on the back of the disc frame. Those plates would keep it from falling off, and not catch the pole when lifting it up on.

The 37 was avaible either way. Just depended on what you wanted and ordered, same with blade spacing of 7" or 9" and 16", 18" or 20" blades.
 
I use a plastic wire tie to mark hoses. I mark just one, and it"s the one that goes in the left side of the remote valve. Tape comes off too easily.
