L3650 2wd transmission/hydraulic fluid

[stepper000]

I have a l3650 2wd shuttle shift. The site glass for the transmission/ hydraulic fluid indicates i need to add fluid. Which fill plug fo i use? The one that is behind the seat or the one under the rubber plug in the center of operators station between the floor boards. I looked in the owners manual and couldnt find an answer. Thanks in advance.

They both go to the same place, so your choice.
