This invention relates to a bale loader. More _
speci?cally, it relates to a bale hoisting device '
for receiving bales. from a pick-up baler and
lifting them into a vehicle trailed behind the
baler.
Pick-up balers are in wide use at the
present time, said balers traveling through the
?eld being drawn by tractors or possibly being
self-propelled and picking up the crops to be
‘ baled directly from the windrow.
