Most Case A-6 combines and other pull-type combines had blacksmith made hitches added to pull a wagon along side under the unloading auger. I'm surprised this picker doesn't get a similar hitch added in place of the hopper. The elevator looks tall enough to dump into a wagon. Was the hopper optional? Round tubes on the elevator, for round cups?
Neat old machine, I'm glad it's so original, it still has a few corn cobs on the back. Thanks for posting!
FYI, Massey-Harris made an early self-propeller corn picker that is also interesting. If I remember right, it had a six cylinder flat head Chrysler engine mounted at tire level.
