Abstract
A method for operating a ratchet assembly. The method includes, when a ratchet lock mechanism is in a first locked position, causing a drive mechanism to rotate by operating a steer cylinder in a selected direction until a first predetermined value, which may be associated with an amount of rotation of the drive mechanism, is reached. The method includes unlocking the ratchet lock mechanism, and resetting the steer cylinder by operating the steer cylinder in an opposite direction until a second predetermined value is reached. The method includes locking the ratchet lock mechanism in a second locked position, and, upon locking the ratchet lock mechanism in the second locked position, causing the drive mechanism to further rotate by operating the steer cylinder in the selected direction until a third predetermined value is reached, wherein the third predetermined value is associated with a selected amount of rotation of the drive mechanism.
