L3560 HST transmission drain points .

Hi , the book calls for 11 gallons of fluid to refill this unit . I drained the large plug but only got 6 gallons out . Where are the other plugs ? Thank -you !

The operators manual should show where all the plugs are. My 30 series GL has 4 HST drain plugs. Two on the belly of the main gear case. None came out of the forward one with a recessed Allen drive on mine. There are at least two more on yours that should yield fluid, the bottom of the portal axel gear case, under each rear axel, at the bottom of the portal case.

That's because thats a water drain.

Yep you didn't drain the rear drive cases 2 plugs in the insides of the gear cases.

Odd that the operators manual for my tractor called it out as an HST drain. Because it was. I’m familiar with the drain with the split pin weep hole for the clutch housing. That wasn’t it.

Do you have access to the manual for the OP’s tractor? Looks like it. We do agree on the need to drain the axle housings.
