Start slow. Even at idle, a full size TLB will have plenty of power to do most digging, the movements just won't be fast. As you get more confident in your movements, you can increase the RPMs. It is better to be in control than be fast. If your engine speed is so high that you are overshooting and, in general, just jerky, slow your RPMs down. I don't operate a backhoe for a living and just use mine around the ranch for various projects. When I am digging, I am probably running about half throttle.
