Claim 19:
20. The chute safety system of claim 18, wherein:
with said rotational force transfer assembly in a reset state and said rear gate assembly in said open configuration, said rear gate crossbar is substantially up, said counterweight assembly is down, said sleeve pin is in a portion of said sleeve channel;
as said rotational force transfer assembly begins to rotate, a portion of said sleeve channel is configured to press against said sleeve pin, which is configured to cause a portion of said rear gate crossbar to rotate downward toward said closed configuration;
at some point said sleeve pin is configured to rotate with said sleeve channel as between said distal side and said proximate side and continue to rotate toward said closed configuration;
when obstacle, such as said bovine, is under said rear gate crossbar and comes into contact with a portion of said rear gate crossbar as it is transitioning toward said closed configuration, said chute safety system is configured to allow said rear gate crossbar to swing freely on said crossbar rotational axis and no longer be pulled into said obstacle by said rotational force transfer assembly by
releasing said sleeve pin from said sleeve channel to freely rotate around said crossbar rotational axis, and
allowing said rotational force transfer assembly to continue to rotate on said spool axis without pulling said sleeve pin and said rear gate crossbar into said obstacle; and

with said obstacle having moved out from under said rear gate crossbar, said rear gate crossbar is configured to fall to said closed configuration when said rotational force transfer assembly is in an engaged state.
