Bobcat 320 mini digger - sump plug location

Good day all,
I have recently inhereted an old Bobcat 320 mini excavator. It needs an oil change but I can't correctly identify the sump plug location. Online manual diagrams bear no resemblance to what I can actually see. The sump is protected by a steel plate and the only visible access through the plate shows two nuts but these look to be too far forward to be for the sump. I've not encountered two x sump plugs before so I'm doubtful.
Is the engine possibly mounted sideways?
Any advice is well appreciated.

yeah, nice one Dave!!
Rather than try to remove lots of rusted, seized and rounded nuts, I was hoping for some helpful advice from someone that had knowledge of Bobcats

Now then, I had a 320, easiest machine in the world to service if it hasn’t been altered. Open the back door and there ‘should’ be a rubber pipe sticking out the bottom that’s blanked off, that where you drain the sump. No getting underneath fecking about, I wish its replacement was as easy to do

Hello all, I recently joined the group and also inherited an old 320 due to the person I was helping being cash strapped (provided I can get it going), it has electrical issues but can only find 3 fuses in the engine bay, I'm assuming there must be another fuse board elsewhere on the machine but as yet haven't managed to find it, I'm going over again to take another look at it before I commit to it (2 hr round trip), if you have any pointers appreciated, also appreciated I could buy a workshop manual for it for 50$ but obviously don't want to do that unless I take it on, best wishes, Steve.
