Harvesting Worms with a Winnowing Machine
A little while ago I asked my good friend Jeff “The Friendly Worm Guy” Sonnenburg to make a video of his worm/castings harvesting machine in action, and here it is!
What makes Jeff’s harvesting method really interesting is the fact that he uses an antique winnowing machine (also known as a ‘fanning mill’) to do the job – not a regular worm harvester. He was able to get the machine for a great price, and judging by what I saw in the video I’d say it works very well for harvesting worms. For those of you unfamiliar, a ‘winnowing machine’ is a device used to separate grain from the ‘chaff’ and other debris.
Just a little reminder of the fact that it never hurts to think outside the box (or the bin – haha) every now and again!
Thanks for sharing, Jeff!

this appears to be an old grain seperator as my grandfather used
I have thought for years about using one and have also one
what size of screens do you use?? or can I buy screens from you that would fit my old Eaton grain seperator
