A gate closer for a gate is provided. The gate closer includes a first housing which is mounted to a supporting structure of the gate. A hydraulic gate closer is installed within the first housing. A second housing is attached to the gate and an adjustable arm is installed within this second housing. The first and second housings are installed such that a rotatable shaft of the hydraulic gate closer engages the adjustable arm so that the gate closer can safely and securely close the gate.
