Joystick moves but loader won't go down??? Check hydraulic quick connectors at the valve for the loader. Right under the Right Hand Side of the operator platform you will see the valve and quick disconnects. The outside 2 are for the loader up & down. Disconnect each of them and reconnect and try. Having one of these pop loose is not that uncommon, especially if driving through some brush. Quick coupler may appear to be connected but if popped loose it will stop flow of oil.
