Gravely 30" rotary mower

[53gravely]

Has anyone got the manual on a 30" rotary mower? I need to change the oil in the gearbox. Can't recall for sure the weight of oil and capacity.

I kinda recall my Dad doing it when I was a kid. Is it 90 weight gear oil? Do you fill it till the oil comes out the side vent? Please confirm.
Is there any caveat where it must be non-detergent like the motor oil?

Use 80W-90 Gear oil (API Services GL-5,GL-4) and Yes fill the box till it comes out the side vent. For Free downloadable manuals go here:

Mine calls for high temp grease.
