Although not technically Massey's, Massey research combines were and are sold in the U.S. for ag research purposes. They are built by Sampo in Finland and marketed under the Massey name by Kincaid Equipment, Haven KS. Go to kincaidequipment.com for a look at these cuties. In the 80's, I believe the smallest of these machines was the "8". It has now been updated to the "8xp". I own an 8xp, and it sports a whopping 7' table (5' is available for those less aggressive guys)and 2 row corn head. The cab is almost larger than the rest of the machine. Also built in the 80's were two larger machines, roughly the sizes of the 300 and 410. These have been updated and are still built. I own an '81 "16" (about the size of the 300) we use for research purposes.
