The Philippines also has a nice tracked kubota compact harvester called the DC-60. http://www.kubota.com.ph/our-product/dc-60-2/ -On Alibaba it looks like it costs about $15K US FOB
I found out that John Deere started offering a chinese made combine starting around 2013 (with a John deere diesel engine) with green paint to the Philippines for around $39K US
Very interesting to see that they will offer this scale of equipment in other parts of the world. It would be nice to see it here in the US. Evidently there is one parked at the headquarters in Illinois but not available for sale. http://www.deere.com/en_US/docs/Corporate/fans_visitors/publications/plowshare_issue33.pdf

Problem addressed/functional need Small scale threshing and cleaning equipment is not easily available in the United States. Older combines have threshing cylinders that are often prone to plugging in weedy conditions - the axial flow design does not have "choke points" that are as vulnerable to plugging because the clearances and threshing area in general, is larger. This documentation is intended to spark new low cost approaches to small scale combine harvesting equipment.
