Yes, beans that are usually meant to be harvested dry have thinner shells and thresh easier than green bean types.
Best to leave them on the plant until they are drying up pretty well. I then pick them and put them in a mesh bag, tie the bag and walk on them. Once threshed, you can pour them from the bag into a bucket with a breeze and the breeze will take most of the pods away. Pour from one bucket to another several times.
Of course if you want, you can always open each pod by hand and take out the beans.
