If you have trouble with cleaning out your narrow bucket while dumping I've seen buckets where the owner has welded a heavy chain inside the bucket. One end gets welded on just behind the teeth and the other end close to the top where the pins are. The idea is that the chain is long enough to lay flat against the back of the bucket while digging and then as you dump it's something that helps the dirt to fall out. It's also something to rattle around inside the bucket to encourage the mud to fall out.
