how do you add hydraulic fluid to a David Brown 990 tractor?

I assume all DB 990's are the same. While sitting on the tractor, you will notice a "plug" located on top of the transmission above clutch pedal. I use a rachet from my socket set to unscrew the plug.

The dip stick to indicate oil level is located across to the LH side just above the brake pedal and slightly under the instrument panel.
