Imagine the consequences if you could easily bump the freewheel while using the winch to lift/tow/pull something.
This can be fixed by "re-working" the mechanism. We made a compact shoulder out of a modified winch in 2005 and never had a problem once we worked it over. It cost us $70 and we had to machine 2 parts (motor mount and input shaft) to get it to work. It's a cheap solution that you can make work with minimal effort if look around.
