Cub 3186 Mower Deck Gearbox Oil

[MarshSt]

I have a 1999 Cub Cadet 3186 with a 190-289-100 mower deck. I dumped the mower deck gearbox oil for a change and can't find the recommended oil spec in any of my manuals. Can anyone help out with info on the correct oil type?

Thanks,
Steve

I don't have any direct knowledge on this machine but most gear boxes use 80-90wgt gear oil.

Mower gear boxes run hot. I use 75-90 or 80-90 synthetic gear oil in my gear boxes. I have found synthetic oil tolerates heat better than dino oil and provides better protection. One major car manufacture is now using/requiring 0-20 synthetic oil in it's vehicles. 0-20 oil???????

Thanks for the info. The oil smelled like typical gear oil but I figured it wouldn't hurt to check. I think I'll give the synthetic a try.

Use synthetic, UPS does on all delivery truck rears. UPS has the data base proving the added value is worth the extra cost. :thumbsup:

I went with Valvoline 75-90 Synthetic. From what I hear UPS has got PM figured out.
Thanks for the advice.

FYI: Cub Cadet Customer service ---or TOTAL LACK OF-----update:
I also submitted an on-line request to the Cub Cadet Support Center 5-04-12 requesting info on the mower deck oil type. I received a confirmation number and a promise of an answer within 3-4 days. 13 days later and still no answer. It still shows "unresolved" in my account. Maybe they can just link their site here to get some real results
Thanks again for the help.
