Since you are unlikely to ever need to push the bucket ‘flat bottom’ across the ground, i would just add some brackets to the bottom of the stump bucket and move those pin locations downward. BUT, si ce you may run into this problem over and over if you plan to continue buying JDQA attachments, it may be worth the trouble to modify your loader with the extra pin location. But it may result your loader brackets hanging below the bottom of some implements. Usually the heel of the attachment is not exposed to anything dangerous so that may be a non issue.
