14. A power machine comprising:
a main frame that includes a rear portion defining a power source bay and a tower structure along a lateral side of the power source bay, the tower structure including an inboard wall and an outboard wall that define a rear frame pocket;
a power source supported by the main frame within the power source bay;
means for transmitting power from the power source to an interior of the rear frame pocket;
a lift actuator assembly that includes:
means for converting the transmitted power to rotational power, located within the rear frame pocket and aligned to rotate along a rotational axis; and
means for converting the rotational power to extension and retraction along an extending axis, operably connected within the rear frame pocket to the means for converting the transmitted power, the rotational axis being located alongside and rearward of the extension axis; and
a lift arm structure including a lift arm secured to the means for converting the rotational power such that the means for converting the rotational power extends toward the lift arm and retracts away from the lift arm, to be raised and lowered relative to the main frame using the transmitted power from the power source.
