Stuck mower coupling

[polk county]

You know that rectangular coupling that the mower blade mounts to? I want to remove it but its frozen. I tried using a jaw puller but it wont budge. Its rusted as usual. Any Ideas? This is what Im talkng about http://theepicenter.com/giffiles/tipoweek/lpuller.gif
Thanks

Re: Stuck mower coupling

Your link will not work but I understand.....

Soak it with pb buster and possible a LITTLE (little) heat from a propane torch because that shaft runs through a seal......

Maybe a puller, pb buster, heat and a slight tap with a hammer. If all else fails and you are not going to re-use the part...... use a grinder to cut it down and slice it to the shaft.
