With the straps, stands in place curling the bucket lifts the back end of the loader out of it’s mounts.
Whatever that is on the bucket is not for removing the loader. As mentioned, you use the stands under the lift arms and that's a common Kubota thing. I've seen many of them in use. Your bucket does look like original paint but it's possible it's a modification. It looks more like some auxiliary piece of equipment that attaches to the bucket. I think I have seen those side brackets before but can't recall where or when.
Strange: I used them many times to remove the loader on my Kubota!
Most of the time the brackets (legs) get lost or missed placed....
Old style no support legs on the loader arms....View attachment 676305
