Port-wise, you’re looking at 7/8-14 UNF-2B SAE O-ring ports, listed as 7/8-14 straight thread O-ring ports. That matches the common SAE straight thread O-ring style in that size.

Run it for about an hour at roughly 30% of rated pressure before you put it under a full load. Make sure the motor is primed with hydraulic fluid before you ever apply any load to it. Skipping that step is usually what causes early wear on these. Following that break-in sequence goes a long way toward getting the full service life out of it.

This S Series Geroler motor is applicable for use in seeders, according to the product information. It's also good for agricultural augers, food processing, and machine tools.
