A boom lock having an actuator and a hook assembly locks a boom of a work vehicle to a swing frame. The hook assembly is pivotally coupled to the swing frame and comprises two hooks and an actuator plate. The hook assembly has a locked position wherein the hooks contact a catch assembly located on the boom and an unlocked position wherein the hooks do not engage the catch assembly. The hook assembly is moved between these two positions by the actuator. The actuator is provided with a fork having an upper tine that contacts the top surface of the actuator plate and a lower tine that contacts the bottom surface of the actuator plate. The actuator is pivotally mounted to the vehicle by a bracket and is provided with a latch for latching the actuator in a first or second position.
