Where is the transmission/hydraulic drain plug/plugs for bolens g274?

[CutTheHolesOut]

I need to change the trans/hydraulic fluid in my bolens g274 (same as iseki te4270) and do not have the manual. Does anyone know where I can find the right bolts to drain it? I heard there might be two in the rear and one in the center but i would like to be more certain of the locations before I do anything I might regret.
