Hydraulics quit working

[orygunparson-HT]

I have a Yanmar 155D. The hydraulics quit working and I noticed hydraulic fluid pouring out from where it appears to the throttle/governor(?). I don't have a manual that clearly shows where the problem could be. This is a tractor that I inherited from my dad's estate, so I'm very new at this. Thanks for any help you may provide.

Thanks for your reply. Do either of these manuals have a section that addresses hydraulics specifically - such as a troubleshooter?
I believe I need the basics on the Yanmar 155D hydraulic system.
Thanks again!
