1. An agricultural equipment assembly comprising:
a first actuator comprising a first cylinder and a first piston telescopically movable in the first cylinder;
a second actuator comprising a second cylinder and a second piston telescopically movable in the second cylinder;
a first lock pivotally connected to the first cylinder and movable between a first unlocked position in which the first lock does not prevent the first piston from moving relative to the first cylinder, and a first locked position in which the first lock inhibits the first piston from moving relative to the first cylinder;
a second lock pivotally connected to the second cylinder and movable between a second unlocked position in which the second lock does not prevent the second piston from moving relative to the second cylinder, and a second locked position in which the second lock inhibits the second piston from moving relative to the second cylinder; and
a control link operatively connecting the first lock to the second lock, and configured to simultaneously move the first lock between the first locked position and the first unlocked position, and the second lock between the second locked position and the second unlocked position.
