Good morning AlwaysTinkerin.
Is there a model identification label on the machine itself (possibly located under the seat) to get specific information on your Toro Groundsmaster 72? If so, a photo of the label would help. :-)
Can you find any identification labels on the Hydrostatic Transmission to determine it's actual make and model?

HydroGear labels would look something like this: -

Peerless labels will look like this:-

Some information may be obtained from the number stamped on the Peerless (shown below), but it's better to go from the manufacturers label identification, as it's more detailed: -

If you could provide photos detailing this information, then it would be easier to find the manual relative to your specific transmisson to answer your questions.

Thank you.
Daryl.
