Amazing mechanic machine

At some point, this summer in Japan we went to meet some friends and visit their seedling farm: with great amusement and surprise I spotted this incredible machine to process rice. It's still perfectly working and at the time of harvest it must be spectacular to see it do its job: get the husk out and sort the seeds by their size.

 The main hand crank to power it all...

 

This is a separate machine, used to take out rice from the stalks: super sturdy metal frame and pedal power. I used a similar machine years ago, but this is truly an antique beauty... 

All perfectly working: amazing treasure indeed!
