The way combines work

Do small grain combines sort weed seed and small kernel pieces out and store that in a separate bin? If so, what do you do with the proceeds in that bin? It seems to me that was the case, a very long time ago when I was closer to farms and machinery. It would make sense to not sow the weed seed as you combine. steve

They are blowed out the back of machine. So you do sow weeds.

Our neighbor when I was growing up had an old pull behind combine and I do remember a 5 gallon bucket on the side that I believe collected weed seed.

The weed seed is blown out the back of the combine with the chaff . There were and probably still are attachments that help clean the seed more on a combine but I dont know that it stored the weed seeds

I don't know of any North American modern combine that saves weed seed and such in a separate bin. That was most likely more important in the era when mechanical control of weeds (cultivating) was the only option available to a farmer. It would be interesting to know if weed seeds can be burned in a stove like corn. Most likely the commercial seed companies do not want to see an affirmative answer to that. But like I joke with people the minute somebody finds a use for lambsquarters,ragweed, waterhemp, etc. those nuisance plants will cease to be prolific in the field. Even if those weeds got help to grow.

I remember a place to attach a bag under the scour kleen. That was on a case pull type dad had at one time. But the scour kleen could have been on any brand.

No one cares about replanting weed seeds now , they just spray the heck out of the field with herbicide.

We used to have a scour kleen attachment on the combine to which a bagger was fastened, bagging the weeds seeds for burning

Once you have dirty land the combine just keeps amplifying the problem. Its not like when people used the thrashing machine. All the weeds went in the straw pile. Nowadays farmers are spraying for every little thing. Quack grass has to be the toughest to control with out spraying it. Plus many farmers just direct seed and rely totally on sprays

The Scour Kleen attachment was made by the Hart Carter company, and it was common to find them on pull type combines, and occaisonally on a self propelled. I'm guessing that a number of things ended their use- one being chemical herbicides made weed control easier, combines got bigger and the scour kleen would need to be bigger, and combines were used more and more for corn, which would likely require removal of the Scour Kleen attachment.

Side note- there is a building in Gridley, Illinois (one town west of the inlaws) that was a Hart Carter plant. I'm not sure what they built there, but the building is still lettered for Hart Carter.

Yes small combines do but they haven't made a small combine for 40 yrs. Pa had a scour clean on the A-6 Case. Instead of a bag he hung a 15 gallon barrel with some chains. When combining beans if he came across a button weed or cockle burr that we missed when walking, he would stop and pull it and wad it up and shove it in that barrel. Two 38 rows of beans with the A-6. Round and round he would go.

I have a Scour/Kleen attachment in my shop. Came off a Deere.
I would like to get it set up as an independant unit, just
for show and tell.

With proper management you should not have many weed seeds to spread but your neighbors will be happy to share theirs.

Long ago I worked at a large elevator. They separated weed seed from soybeans, as I remember there were a couple train car loads of weed seeds. I suspected they were used in feed, for instance when we spread manure from my grandpa's chicken house there were a lot of weeds growing from that.

It makes me feel good to intervene in a small way in weed propagation, especially on my home place. When I happen to notice an especially large one I may pull it up to prevent it from going to seed. Yesterday while walking past a stone wall I noticed three tall ones with mature flowers. I pulled them so they won't go to seed. The flower petals were gone on a third one, and when I pulled it a cloud of tiny seeds was released. This has been happening many times over every year since man's original sin. The ones coming out the back of a combine are insignificant.

I had a international 203 combine that had a scour clean on it, and my dad had an allis chalmers 66 with an engine on it, that also had a scour clean on it.

I have a neighbour a few miles and an uncomfortable busy highway away. He is certified organic, which is the way I would have gone 35 years ago if I'd stayed around. Paul is good at it as he is stubborn, I know, I used to wrestle him, NCAA rules at the time. His fields these days are incredible for clean considering Certified organic. He stays on top of weed propagation and has for years, since '97. Not an easy row to hoe. I choose to think of those plants as unwanted plant species. I get a certain sense of enjoyment in pulling plants from the garden and getting them by the roots and the roots letting go. Burn the seeds, put them through livestock. We're just putting them back out there. They were here when we came and be here when we leave.

This one was invented by a French custom harvester about 10 years ago. Not very common but you see them here and here. The chaff and seed is collected for fuel.

Sourklean screen attachment with weed and small grains bagger were available up to the 60s.

Where do you think that straw pile went? Under the animals.

What happened next? The stalls would get cleaned and spread on the fields.

Guess where those weed seeds ended up. Won't keep you guessing. Right back in the field.
