Agricultural Microcombine (Combine) - a combine is a complex device that cuts, threshes, and winnows grains and field crops of all sorts. Modern combines are huge devices today, and a smaller one is desirable for a small farm. This is not to say that this design should not be scaleable to larger size, as required to feed larger populations effectively. We propose a hybrid combine, with all parts driven by separate, infinitely speed controllable motors. This eliminates all pulleys and complexity of a single power source powering the entire modern combine. The key here is availability of cost-effective motors and controls, where today, motor controls are prohibitively expensive for such a proposition. OS changes this. With a microcombine under the control of the operator, expensive maintenance is avoided, and full food sufficiency becomes feasible on the tens-of-acres scale.

==Review of Project Status==

The status of the project is "We are getting started now, as of April 25, 2011.

==Combine - Current Work==
Current work includes getting information from grain and bean farmers about their needs for a microcombine, the operation modes they'd like, etc. and surveying any commercial equipment available that is similar in scope/scale.

==Combine - Current Work -- Desired Features of the Microcombine==
This category is for grain and bean farmers to comment on the features they would find useful in this machine.

==Combine - Current Work -- Survey of Existing Commercial Models==

Small Scale Grain Production Today -- this link is to an article at the website of a commercial dealer in imported European machinery. He has some pictures of stationary threshers that run $5K - $26K. There is a survey of commercial small combines presently being manufactured in Europe and Japan. These small combines retail for $40K - $77k.
