The present invention relates to new and useful I
improvements in corn pickers, and has for its
primary object to provide, in a manner as herein
of the truck body 2.
after set forth, a machine of this character which _
mounted on aframe structure 5. Pairs of spaced, ’
parallel guides 6 are mounted in the lower, inner
portions of the housings 4. Slots 1 in the inner
walls of the housings 4 communicate with them
Another very important object of the invention
_ is to provide a corn picking or harvesting machine

more suitable hangers 4'. A hange; 4' prime may
