The extension includes a support member including a mounting end mountable to
a corn header adjacent to a rear end thereof for pivotable movement about a generally
upwardly to downwardly extending pivotal axis between at least one forwardly extending
position spaced above the end hood, and a second or stored position at angle to
the forwardly extending position or positions. The support member has a free end
extending upwardly and outwardly from the mounting end to a terminal end portion,
and supports a sheet along substantially the length thereof to serve as a barrier
to the passage of corn between the support member and the end hood and to deflect
ears that strike it into an adjacent crop gathering channel. When it is not desired
or required to use the extension it can be quickly and easily pivoted to the stored
position, out of the way.
