B20 hydraulic reservoir

Is the transmission the hydraulic tank for the whole system on a B20

It is on the B21, so I would assume it is also on the B20.

The transmission and the tube that runs under the tractor. I guess it is about a 6" tube and runs left to right under your feet. There are hyd lines running to it and drain ports.
