how transmission oil capacity
any hydraulic transmission oil such as Hy-tran Case IH or Hy-Gard John Deere
The hydraulic reservoir on the case 730 should be in about the same area as the case 630......on the right side of the tractor at the rear of the engine and on what would be the bell housing is a large cap screw type plug. There should be a dipstick not too far from it....you add hydraulic oil there, if it is a case-o-matic. If it is a standard transmission, then the dipstick and the plug should be on the rear of the tractor around where the seat bolts on.
Universal Trans / Hydraulic Fluid (Some Wal Mart Locations, Any Tractor Supply, etc)
Go to your local parts store or fuel jobber and get a can of Tractor Fluid or your dealer and get OEM fluid. About 50 bucks a can but a lot cheaper than a hydraulic pump failure. Good Luck!
Hydraulic fluid is hydraulic oil.... as for the type you use, depends on your system. I used to own two tractor-trailer end dumps, and I actually used ATF rather than hydraulic oil. Check with the OEM for your hydraulic system before you do this, though.
Automatic Transmission Fluid Type "F"
Back when that tractor was made, they probably said to use an SAE 10 or similar hydraulic oil. Now days, the Universal Hydraulic Oils that are available meet and exceed the specs on those older type oils. You should be able to get Universal Hydraulic Oil from about any oil distributor or farm supply store.
It uses Hyster Hydraulic Fluid
Go to your John Deere dealer and pay big bucks for their hydrostatic fluid or go almost anywhere else and buy a good quality hydraulic fluid.
Any kind of hydraulic fluid, it is all fundamentally the same.
