Deere TWA or 1635 ?

I need to find out what disc this is. It looks like OP changed the bearing hangers to beef them up. I think the blades are 28", will measure later. It has a single cylinder that blew both end cap seals when it was lifted and the rod wanted to bend real bad. I think it needs a longer lever arm. OP put a hydraulic rear slider on it, I think. How about it? Value ?
 
Having trouble with pics. It may be that my jpeg files are upper case and not lower case. I'll have to ask my son to fix that. I never had a problem using them before.
 
I just found out it has two, one is below the other one with the angle iron in the front broken, no hoses on it. It has 28" blades. I think it wont load the pics because my puter has them in upper case. I can see the picture but it just says begin uploads above the pic. Any idea of value?
 
How about it Tx Jim, I noticed the cylinder arrangement on the 1635, this has one mounted under the other one. />

I see the different main frame, I don't think its a 1630,1635, or 1640 either. I have no clue, its built like them and has 28" blades which could be replacements. I thought you might know the model number. Do you think its another brand someone wanted to be a Deere? I only see green and yellow paint. I sent pics to the Deere dealer but he hasn't responded. The front beam has a Y-brace behind it.
 

It looks like the back cylinder was added to change the angle of the rear gang from the tractor. It doesn't really look like my TWA. First off, it only has two hangers per gang, and my TWA has three. Is there no data plates on it? Whats that dark spot in the middle of the front?

Maybe an oliver?
 
There's a steel plate welded there that looks like it had an ID tag on it. The PO advertised it as Deere. It has another cylinder mounted under the top one.
 
The frame is identical to a PICO disk that we've had for years. The only difference I see is the bearing hangers, ours uses sealed bearings that are flange mounted. PICO is Poplarville Implement Co. They were built in Poplarville, MS. Very heavy disk.
 
Also, ours bent a cylinder as well. The rod was to long, and the clevis bound on the lever on the cross tube. Ours does an excellent job of cutting hard clay soils, but it takes a lot of hp and eats bearings. I can easily see someone modifying the bearing setup to try and fix it.
 
Its hard to see but there is another cylinder underneath the one on top. Using just one cylinder to lift it blew the seals on both of the end-bolted plates.
 
From what I can see, the cylinder on bottom is set up to change the angle of the gangs on the front. Originally it probably had an acme thread rod located underneath at the front to make the adjustment, and another at the rear on top for the same purpose. At least, that's how ours is set up (another farmer modification I can easily understand as the threaded rods were subject to seizing up). I skinned a lot of knuckles as a teenager making those adjustments. A single 3 or 3.5 inch cylinder will easily lift that disk, ours is a good bit wider than the one pictured (14')and only uses 1.
 
Thanks for the info, I thought it was a Deere as it's similar to them. Its in pretty good shape, it just needs a little tweaking.
 
Gary201, do you notice if the clevis mount is different on this disc? I dont think its long enough for good leverage. Like I said it blew both end seals and curved the rod when lifted.
 
I think the size and style of the cylinder pictured is more than sufficient to lift it, the lever and mounting arrangement is identical to ours. Looking closer at the picture, it appears that the bottom side of the clevis will contact the lever when the cylinder fully extends. This will cause the rod to bend (exactly what happened to ours). Try to find a cylinder with a deeper clevis or grind a relief in the lever to ensure clearance when fully extended. The cylinder may have been overdue for the seals to go, most are rated to withstand more pressure than a typical farm tractor can supply. The rod bending could certainly have contributed to its demise. I will try and get some pictures of ours this weekend to refresh my memory of how we addressed the issue.
