What Ricky said pretty well covers it. I think the deactivated sulfur approach is why they initially though that GL-5 could be backfit to places that used GL-4. That didn't work out so well. Today you can run across oils that are labeled GL4/GL-5. A lot of the observations/rumors suggest they are really GL-5 and not totally trustworthy for a GL-4 application. I always thought, but have no proof, that gear oil odor is mostly from sulfur.

HY-Tran, and I believe the compatibles, conform to GL-4. Viscosity Oil Company has advertising that goes to great lengths to talk about how safe it is with yellow metals. Other high quality hydraulic/transmission oils probably are as well but I have not checked.

I'll stick with the GL-1 in my Cub low performance gearboxes.

For reference - The 140 does have an aluminum slinger "gear" to throw oil.
When you only have 9 horsepower you need to know the names of all of the ponies!

Pot metal as I recall. Either way, it has a "yellow metal" bushing. Steering gear of both the Cub and the A/140 does as well.
