I have a toothbar. I love/hate it. Depending on what I'm doing. As I've read this thread, it is painfully obvious, I need to design a way to keep it on, take it off in less that the 5 minutes it takes to unbolt it. I'll be thinking on it..
Admitedly, since I put a thumb on the backhoe, the usage of the toothbar has gone way down. Before that, I couldn't have lived without it.
One thing I have heard of being done is to drill, or elongate the mounting holes in the bucket so that you can just loosen the bolts, pull the tooth bar ahead, and then flip it over...... no need to fully remove it.
