‘My invention relates to improvements in load- ‘ : eluding a front, relatively short, vertically swing

A suitable motor 32 on the chassis frame I is
operatively connected to ‘the described‘conveyor'

connects said shaft 33 to the conveyor driving
shaft 20.
Extending transversely between the front ends
of the side frames l3 of the vertically swingable
section I I, in advance of the described conveyor,
is a bale pick-up roller, substantially rectangular
Referring now to the operation of the described
apparatus, normally the shoes 43 are designed to
ride over the ground and support the pick-up
roller 39 slightly elevated above the ground for
free rotation, the section II, because of the de
scribed swinging mounting thereof, being free to
float or ride over uneven ground, as will be clear.
In this connection, the described means for swing
ing the section H is particularly adapted, be
cause of the pivotal connections 43, 52 to permit
free vertical ?oating movement of said section H
in cross section, and journaled at its ends by stub
shafts, as at 31, in bearings 38 on the front ends
of said frames.

of course, providingyfor pick-up operations over
