Abstract

An improved directional control apparatus for a bale thrower on a baler includes an elongated arm pivotally mounted at one end to a side of the bale case of the baler and extending generally across and under the end of the thrower being pivotally mounted to the discharge end of the bale case for side-to-side lateral swinging movement. The control apparatus also includes a hydraulic cylinder interconnecting the bale case and the free end of the elongated arm and means for slidably interconnecting the arm to the thrower such that upon actuation of the hydraulic cylinder to pivot the arm, the interconnection established between the arm and the thrower by the slidable means will cause the thrower to also pivot or laterally swing and thereby vary the direction in which bales will be thrown away from the baler by the thrower.

Dependent claims

An improved directional control apparatus for a bale thrower on a baler, said baler having a bale case with a bale discharge end, said bale thrower being mounted on said bale case at said discharge end thereof for lateral swinging movement relative to said bale case about a first axis and for receiving bales from said bale case discharge end and throwing them away from said baler, said improved directional control apparatus comprising:

an elongated arm pivotally mounted at one end portion about a second axis to said bale case being displaced from said first axis and located adjacent one side of said thrower, said arm extending generally transversely across said thrower to an opposite end portion located at an opposite side of said thrower;
mechanism interconnecting said baler and said opposite end portion of said arm and being actuatable for causing pivoting of said arm about said second axis relative to said bale case;
and
means mounted to one of said thrower and an intermediate portion of said arm and slidably connected to the other of said thrower and said intermediate arm portion such that an interconnection is established between said arm and said thrower which will cause said thrower to laterally swing about its said first axis as said arm is pivoted about its said second axis for varying the direction in which bales are thrown away from said baler by said thrower.
