Kidney beans havestor

The bean  harvester is a Bob's Model 56. I owned the next size larger a Bob's 666.

It reminded me of a pull type peanut combine when I first saw the video.

Growing areas are primarily western Ontario, the thumb of Michigan, Minnesota, and southern Manitoba. The harvesting  process is first to cut the plant off just below the ground with a knife puller. This is done with dew on the plant so the beans don't fall out of the pod. We usually started about 4am. Beans are then windrowed with 6 or more rows on a windrow. Combining starts at noon or when the pods are dry. The Sund pickup on the video is superior to the one that in normally on the combine. The rakes are used to bring the beans up to the first spike tooth cylinder. The pan under the rakes is perforated and the rakes help to shake the ground off the roots. Mud is not our friend. The first threshing cylinder can run as slow as 56 rpm. Behind the first cylinder are straw walkers about 6' long. At that point we want about 90%+ of the beans out of the pods. A second spike cylinder runs about 30% faster and threshes the remaining beans except for a very few. Several times per afternoon I would stop the combine full , partially lift the bin and crawl into on top of the walkers. I wanted to find one or two pods unthreshed  on the second  set of walkers. If they were all threshed, I slowed down the cylinders to minimize the skin damage. If too many were  unthreshed, I sped up the cylinders. The bin tips into the truck because augers cause a lot of damage. It's been 20 years this year since my last crop of Kidney beans. Combines are now a higher capacity rotory type. The harvesting process is very similar to peanut harvesting 

Gleaner sold units set up for edible beans that were used in kidney beans  most had spike cylinders and spring tooth doors. The spring tooth provided protection from the rocks and hard clods that sometimes accompanied these crops.  Augers were trimmed back and then 'popcorn' augers were used that had special smaller flighting to help control bean damage.  Just a falshback memory when viewing the neat video.
