PTO conversion gearbox ?

Hi Guys

I have a PTO conversion to std rotation on my Beaver, does any one what grade or oil that thing takes ?

I assume it standard gear oil, but figured id ask you guys

The service manual doesn't appear to specify a gear oil weight, but I'd think 80w90 a good bet and is what I'd probably try if I had one of those reversers. They specify both 80w & 90w for differing parts of the Mitsu rototiller.
