The present invention relates to balers and an
object thereof is to generally improve the con
struction and operation of devices of this class.
Further objects are to provide an improved feeder
head vconstruction‘for a baler; such mechanism
actuated directly from the main crank and safety
means for preventing damage in the event that
the feeder head is inadvertently blocked. A par
ticular object of theinvention is to provide im- proved chassis‘construction in‘ a baler to facilitate
transportationand including an improved tongue
orv draw bar forattaching the baler te a propelling
vehicle and adapted to support the baler for op
eration. Further objects and advantages will be
come apparent from the following description and 15
accompanying drawings in- which:
