Kubota Hydraulic leaks

After recently getting a older B series home it is leaking hydraulic fluid from underneath, cant tell exactly where it is coming from but the housing somewhere.. Curious if 1) this could have been caused or made worse by it's trip on a flat bed car wrecker? Maybe from the angle it was at when loading/unloading? Dunno.. It didn't leak before the trip! 2) Do any "stop leak" products work or are they a bad idea? Like Blue Devil? Seems to have a lot of good reviews...

Is there some sort of an overflow up on the HST or something ?? I can't figure where this is coming from but the frame has a square cutout underneath in center and its dripping from that area. I look up and see 3 bolts up there, maybe one is a drain plug

Pictures, talc, find the leak, don't use stop leak.

When does it leak? When it isn’t running, when moving (hst), when using the loader, and/or using the three point?

There is an overflow usually but a simple incline of loading should not cause that unless the fluid level is too high. That brings up another point is the fluid level between the marks on the dipstick and it not overfilled?

Best to check all fittings that you can. Something could have vibrated loose if it was on the verge of coming loose.

Thanks. I ended up selling the tractor as is because I didn't want to deal with the leaks.. It didn't appear to be any sort of line/fitting but coming from the case underneath towards the middle. Leaking as soon as you start it about 1 drop the size of a quarter on the ground per second... Didn't get worse when you worked the loader or backhoe but just steady dripping that eventually let up after the engine was shut off only to start when it was started again. Did it moving or not. Much of the underside was wet with fluid. Fluid level seemed ok on the stick, maybe slightly high but not coming out cap or dipstick area or anything like that.
