my most recent tractor, a (gasp!... Kubota!) has the SSQA mounting system on the front of the loader arms. SSQA stands for "Skid Steer Quick Attach" and what it means is that any tractor with a SSQA can quickly manually attach any SSQA attachment and it will fit and the geometry will work.
It takes maybe one minute to do. Now any bucket that will fit a skid steer will also work on the tractor - although some do require aux. hydraulics. But the world just got a lot larger.
I love that SSQA for the options it gives me, the SSQA system would also fit most any Yanmar or other make loader from about 25/30 hp & up.
But of course now we're just dreaming. A simpler truth is that on your existing loader you can do just as you guessed and as California says, Take out the 2 pins on each side, lash the cylinders to the arms so they don't bounce, and leave the bucket behind.
