what command?

I found a chief trader post, and I managed to save the dying crops on his roof and they're ready harvest however, because of the trader's land claim I can't just harvest them normally. I think killing the trader would remove the land claim, but I don't want to do that in case he has a good quest later on. I've tried turning off land claim but that didn't work and I don't have a bucket yet so I can't dump water the crops to harvest them. so, does anyone how to get rid of the land claim without killing the trader?
