I think you are confusing the UTF and Hydraulic oils. The hydraulic oils are sold in a variety of voscosity grades that are designated as AW or ISO followed by a grade number - e.g. AW 32/ISO 32, AW 46/ISO 46, etc. The AW designated oils have the same viscosity as the corresponding grade ISO labeled oils but contain a more robust anti-wear additive package. You do not want either of those for your N-series tractor.

UTF on the other hand is not typically labeled with a viscosity grade. You would have to get the product data sheets for each brand to find the actual viscosity but for practical purposes they are all the same. In your list the Premium UTF products are CAM2 PROMAX J20C, Harvest King Trans Hydraulic Fluid, Harvest King CASE IH fluid, and Shell Spirax S4.

The other trans/hydraulic fluids are lower quality (e.g economy) fluids with a less robust anti-wear package and lower viscosity index (e.g. poor cold weather hydraulic performance).

If you go into TSC you will find a similar offering with Traveler Premium Heavy Duty trans/hydraulic fluid being the house brand.
