I made an adapter, so I can remove my bucket (3 pins), and put the adapter on, then use any of my non-pto powered 3pt attachments.
It works great for some (Forks, subsoiler), not so great for others (blade).
There are 2 problems for the blade on my Kubota 1830. 1, is the blade is too far in front. And, the other, more important, is that the loader arms are very high when the blade is just touching the ground. That makes for some interesting angles when plowing.
I ended up putting a front receiver hitch/bumper on my tractor, bought an old snow-bear brand (Lowes, home depot) snow blade. I mod'd the blade to fit in the hitch receiver for easy hookup, and lift it with my loader. Works like a champ and keeps the pushing forces where they belong.
