1. A machine comprising:
a frame;
one or more lift arms coupled to the frame and movable relative to the frame;
a sensor;
an actuated pin assembly comprising a locking pin actuatable between a stowed configuration and a locked configuration; and
a controller configured to perform actions comprising:
with the actuated pin assembly in the stowed configuration, receiving a signal to lock the one or more lift arms relative to the frame,
receiving sensor data from the sensor,
determining, based on the sensor data, a position of the one or more lift arms relative to the frame,
based at least in part on the position corresponding to a locking position of the one or more lift arms, actuating the locking pin from the stowed configuration to the locked configuration,
with the locking pin in the locked configuration, restricting power to an actuator configured to actuate the one or more lift arms relative to the frame,
with power to the actuator restricted, actuating, via the actuator, the one or more lift arms to move relative to the frame such that the frame and the one or more lift arms are in contact with the actuated pin assembly.
