Long disc questions

[CMMC]

Hello to all the available knowledge out there! First off thank you for reading my post.
To the business at hand, I came into a Long disc that I helped a friend dig out of a berm of sand. The thing is red and says LONG in white on the front of the frame and the "wiper" mounting bars are also white. Looks like the discs themselves were black at one time. LONG is the only marking whatsoever . It has 18 discs across the front (looks like could have been 20 at one time) and 18 or so on the rear. The discs are 20 inch + in diameter. Has spindles for four tires that are in serious need of replacement (the two hubs that are there currently have really old rags for bearings) Anyway, I am trying to get her up and running.

1. How do I determine the requirements for a hydraulic lift cylinder for this thing? It does not have one at all and appears to have been heavily wielded for both attachment points. Do I measure maximum points of travel? Minimum lift capacity should be more than the disc by how much due to leverage?

2. This disc is a configurable geometry type that can be set almost straight for the front and rear disc setups or almost an X. I have noticed that the front 2 leading discs on the outside and the rear 2 leading discs on the inside are significantly smaller than the others due to wear. Is there a standard procedure for this? For example rotate end to end, buy replacements and rotate, buy replacements and just put em on etc..?

Is there any way to determine the model of this disc? I am more than willing to post pictures if anyone might think they will help and if I can figure out the process. If I am overthinking any of this please let me know. I am obivously just getting started on a shoestring and any and all critique is welcome. Additionally the only source I have for parts within 120 miles is Tractor Supply, it is better than what we had before NOTHING.

Thanks in advance for your input.

Any ideas would be greatly appreciated!

If you could post a picture of it would help. Long did not manufacture there equipment they bought it from other builders like Oliver, Zeter, Rowanoke, Fiat amd many others. If you post a picture some one here can tell you who made it and what the cylinder should be. Bandit

Thanks very much, a picture should be posted within a day or so.

The outside blades are suppose to be smaller.It is not from wear. You don't want to throw to much dirt out that the back gangs cannot pull it back in.

The outside rear blades are smaller so you don't leave a deep furrow. We call those outside blades on the rear furrow fillers.

My bigger disc has 22" blades for the main section and has a 20" then 16" blades on the outside of the rear gangs

I think an older tandem disk had disks/blades all the same size front/rear when it was new except if it had a furrow filler attachment. A 3X8 hyd cylinder should be adequate to raise/lower tandem disk

I also just bought a Long disc and the guy I bought it from had the parts book and a brochure from 1964.
If you can give me the width I should be able to give you a a model #. The colors are the main frame and scrapers were red and the tube holding the disc were white in the brochure. The tube that has the tires comes in 2 lenghts.. 99 5/16" model 958 or 135 9/16" model 959. Duel wheels were optional but standard on model 961.

Hey guys, here are a couple pics hope they help. I can take more if needed from any angle you would like. Thanks again for all the help!

that is a good disk
outside blades are to be smaller
probably only setup for two wheels
3x8 or 3.5x8 cylinder
very easy to adjust angle of cut as needed for working ground
pulled one for my uncle for over 30 years
