Always lots better to follow the owners manual. There has to be a reason they call for different fluids. Frank. ....

Doesn't sound smart to use a combo of one viscosity when the manual calls for two products, a dedicated gear oil and a dedicated hydraulic oil of another weight. (It's true that Yanmars use the combo, but I don't know how their gears or hydraulic components are designed differently. Their hydraulics won't work with straight hyd oil.)
It's probably OK to deviate from the manual if it doesn't accept multiweights only because it was written before multiweights came out. ....

Most folks use diesel-formulated 15W40 in the engine. And if the engine is wet-sleeved, you should consider a SCA additive to the coolant. Or better, use a coolant that's already SCA formulated. I buy Fleet Charge 50/50 from WalMart.

Greg: "Yellow metal" is that slang for Japanese/Chinese tractors? Haven't heard that term. ....

It's a generic phrase that includes brass/bronze/copper/etc. Many - not all - of these Chinese tractors incorporate yellow metals into their gear boxes, so it's best to err on the side of caution. I say this, because some gear oil formulations attack yellow metals, notably those with EP additives.
Until recently, that limited us to using API GL-1 or MT-1 rated gear oils, which were difficult to find in multi-viscosity blends. But some manufacturers have seen the light, and it's now possible to buy GL5 gear oils that are approved for MT1 applications. Matter of fact, I just bought 10 gallons of Coastal 85W140 that is rated GL5/MT1

Gregg, the owners man. says 30W, had a mechanic tell me that a non detergent 30 wt motor oil would be fine in the tranny box,,, your thoughts,,, the oil you spoke of is heavy is'nt it ???
I will keep looking for the right hydro oil for that system.
Thanks for your reply.

P.S.,, I am still trying to get myself "broke in" on these Chinese tractors,, I was born/raised on a farm in the panhandle of Tx,, we had JD-Case-Massys etc. so these tractors are greek (Chinese) to me. Thanks again. ....

Clock on Viscosity Chart below. You'll see what I mean (hint: ISO and AW represent the same thing)
