Bush hog

[blaux61]

I just bought a Bush hog 105 used off a guy. Looks to be in real good shape. Not sure on how old it is. My question is what type of oil do I use in the gear box? Not knowing when it was last changed I thought it would be a safe bet to change it before I use it. Thanks for any help

90w Gear Oil but I wouldn't change it unless it is milky (watery).

Yeah, if it looks/feels like 90wt should, then I would let it go the rest of this cutting season, and then change it during the winter so it's ready for next year.
