My Kubota
L3600 had a pin on 4n1 bucket,WR Long, on a Great Bend loader. I ordered a SSQA from WR Long, unpinned the bucket, added the SSQA, picked up a grapple and forks, and after a year finally converted the bucket to SSQA. Glad I did it when I got the tractor, use the forks and grapple a lot, bucket not so much. But with the 4n1 the loader has hydraulics up front for the grapple.. WR Long probably has or can make the parts for your loader and will have the parts to convert you bucket.. At our age, do it sooner than later.
