Those L3130 drain plugs

[cutename]

I am doing my 200 hr maintenance on my L3130HST no mid PTO and all was well until I got to the hydraulic/transmission oil part. The issue is that the manual shows 4 drain plugs. Two "normal" looking plugs and then two plugs towards the rear which I cannot tell from the manual where in the heck they are. My tractor has one plug exactly where the manual shows(second from the front), the front plug is a recessed plug and I still have no idea about the back two. My forum search shows that there is a problem with manual diagram but does not say what the problem is. How many plugs? Where the heck are the back two if the answer is four? Is the recessed plug a drain plug? thanks much.

There is a small hex plug in each wheel end of the rear axle housing. From the rear wheels, follow the axle shafts into the rearend housing(s). Where the rearend housing gets big on each side, there is a hex nut w/washer on the inside side of the housing(s). The small plugs normally have a dab of white or yellow paint on them.
A picture would be better.

Thank you BobinCols. I just used the main hex plug at the 50hr and based on the volume of T-oil retrieved, that worked but I wanted to do it right this time. Appreciate it.
