IH 37 Disc

[carpetfarmer]

I just bought an 8' IH Model 37 wheel disc but it is missing the hydraulic cylinder. What size cylinder does it need to have? 2 1/2" x 10 or 12"??

Honestly, its still sitting on the trailer, so haven't been able to measure the stroke or anything yet

X x 8 inches.

I'm sure he meant to say 3X8. That's what I have on two of my IH 37's.

Actually meant 21/2 to 3 1/2 inches. Smaller cylinder takes more pressure and may be too jumpy. Back in day I think we used 3 1/2 inch behind 400 Farmall or 730 Deere.

Depends on what you pull it with... we had a 6x8 on ours, but the cat we pulled it with only had about 850-1000 psi on the hydraulics

 

[carpetfarmer]

Awesome, thank you!

I had to go to a 5 inch so my dorf had enough pressure to raise the disc with its whopping 6gpm gear pump

Standard 8" stroke 'farm' cylinder. 3" diameter is most common. But 2 1/2 or 3 1/2 would also be satisfactory.

That is a smallerdisk so tractor hydrolic pressure would be determining diameter. A higher pressure system will require a smaller diameter to do same lift as a lower pressure hydrolic system would so depending on tractor from a 2" cylinder to a 4" cylinder but a 2" cylinder would be way faster lift or lower than even a 3" cylinder would and a 4" cylinder would still be a lot slower yet but would lift same load at 250# pressure as a 4" cylinder at 1,000# pressure so need tractor make and model to give good info on that. As far as length it has to be an 8" stroke cylinder, anything longer if you could get it on rven eould breakup frame completely for disk to be beyond repair. For size the size is measured on rear gang amd a 7" blade spacing with 7 blades on a side is called a 8'8" unit, it would have to be a 6 blade on a side to be close to a 8' at 7'6" and I don't think the frame could handle a 6 blade on a side being too wide. My 7 on a side I used a 2.5" cylinder on a 900# pressure system with no problems.

Tractor is a Case 1190. Not sure what kind of hyd pressure it produces. Rear gangs are the same width as my 102" trailer.

 

[DeltaSteve]

That 1190 is a late model,so it will have PLENTY of hydralic capacity(probably 2000 psi). A 2" would probably lift that small disk,but just go ahead and get a 3"x8"(cylinders are measured by length of stroke),as a small cylinder will tend to be jerky.3" is a good 'universal' size,3" will work well for 90% of applications.Now,if you had an old H or M with a worn out belly pump that is only putting out 400 psi,it might struggle with a 4".

 

[Leroy]

That tractor is new enough to have a higher pressure hydrolic system so any cylinder from 2.5" would be good. Just don't tyry to make use of all that horsepower by trying to drive too fast as power wise that tractor has enough to try to go too deep and too fast. Your mig problem will be the small tires, try to find yourself a set of dual wheels if you plan on working previous worked ground like first time over. Not enough float with that tire for rough worked ground. Does your disk have the grease type bearings or greaseless type? Mine was greasless type and sdold it to friend that his was grease type. And 102" trailer being width of disk makes it the 8'8" model.

 

[carpetfarmer]

They have grease zerks in them. I know 3 gang bearings are worn out for sure, but no more than I will use it, it will work for now until I get around to repairing it as needed. One of those implements I don't have a real valid reason for other than its something I wanted... I will use it once a year to disc a firebreak along the neighbors' fields when I burn off the drainage ditch, so they don't lose all their crop residue.

 

[carpetfarmer]

Eventually, I would like to try it with my A/C WC. But it's not even running yet, so I'll cross that bridge when I get there.

I always used smallest cilinder that I had with enough power to lift to get the speed and never had any jumping.
