Substitutes for Transol SPVG 320, 460 or E400

Picked up a new Polish made hay mower . . . gearbox calls for Transol SPVG 320, 460 or E400. It has factory fill in it (thick stuff), but I need to source the first change soon.

I can't find much, but am thinking that an ISO 460 oil is what I need? Something like this:

Thanks for any guidance . . . I have decent experience with SAE motor/gear oils, but am lacking where hydraulic and ISO stuff comes in.

I would try emailing Mobil if you haven’t already just to be sure, but it looks like you’re on the right track.

Thanks - Mobil says it'll work.
