Based upon a previous post where you ask for a parts source, I take it you have no dealer support. It would help to know where you live, where you got the tractor, and who put it together.
The tractor should have come with at least three, possibly four manuals: 1. tractor operation, 2. tractor parts, 3. engine operation, and (maybe) 4. engine parts. The KAMA recommended maint sched is in #1. But I hesitate to offer additional break-in details without knowing at who's done what to it since it got off the boat.
Until then, I can only offer the fluids that I use on my own KM454:
Crankcase - Shell Rotella T 15W40
Front Diff - Shell Spirax HD 80W90 (non-foaming)
Tranny - Shell Spirax HD 80W90 (non-foaming)
Steering - Shell AW32 (non-foaming)
Hydralics -Shell AW32 (non-foaming)
Injection Pump - Campbell-Hausfield compressor oil (ISO 100)
Cooling System - 50/50 low silicate/water (yours may have no anti-freeze)
Please note that AW32 and 80W90 are suited for my year round operating temps here in WKY. If you live in a consistently warmer climate, you could consider AW46 and 85W140
