Just an update on this post. I have an L39 with the BT1000 backhoe and the instructions are in front of your feet on the backhoe controls. It also makes it easier to install and uninstall the pins by using a dremel/air tool with either the round sanding fins or the wire brush attachment to clean out the holes where the pins are inserted. Then I put a little antisieze on the pin. The first couple times I removed the backhoe I had to use a pry bar and hammer to get the pins out. After dremeling the holes where the pins go it made it much easier. Some of the paint and rust makes little high spots that don't allow the pins to release. The other thing to do if the pins won't release is gently raise and lower the back of the tractor off the ground with the backhoe and watch the pins. You will see them slightly move when the pressure is released. My left pin comes right out when I lift the tractor off the ground, but the right pin needs the tractor just touching the ground for it to release easily.
