I believe at the 20-25 hour mark engine oil & filter, along with the inspection of overall machine is called for.... fluid levels of all systems, drive line, suspension, ect.
I did my own first service and changed all the drive line lubricants with the exception of the coolant and brake fluids. I figured it was cheap insurance and should show any major issues.
