A round baler having a single bale forming chamber is provided with an electronic control circuit which makes its operation automatic except for the operator-controlled functions of starting and stopping forward motion of the baler. Under the circuit control the baler forms a bale, wraps it with twine, cuts the twine, raises the tailgate, ejects the wrapped bale and closes the tailgate. The control circuit energizes a first indicator when the tailgate closes to signal the operator to begin forward motion of the baler. When a point is reached in the bailing cycle at which the wrapping of the bale is to commence, the circuit energizes a second indicator to signal the operator to stop forward motion of the baler. The circuit also detects certain malfunctions and energizes a third indicator to signal the operator that a malfunction has occurred.

Semi-automatic baler control and indicator system

A roll baling machine includes an apron supported on a base frame and movable in suitable manner to form roll bales of crop material. A bale retainer is mounted on the base frame to momentarily hold a roll bale upward in the base frame during its discharge therefrom. The bale retainer is movable from an inoperative position during bale formation to an operative position during discharge of a roll bale from the base frame.

Bale retainer for roll baling machine

In a crop roll forming machine having a reversibly rotatable upper bale forming means, lower bale forming means and a drive means there is provided an improved control means affixed to the frame movable between at least a first position and a second position for cooperative interaction with the drive means and the upper and lower bale forming means to selectively cause the lower bale forming means to be driven in a generally rearward direction when the control means is moved from the first position to the second position so that a partially formed crop roll is ejected rearwardly from the machine onto the ground.

Override means for automatic bale ejection drive

In a crop roll forming machine having a reversibly rotatable upper bale forming means, lower bale forming means and a drive means there is provided a control means affixed to the frame movable between at least a first position and a second position for cooperative interaction with the drive means and the upper and lower bale forming means to selectively cause the lower bale forming means to be driven in a generally rearward direction when the control means is moved from the first position to the second position so that a partially formed crop roll is ejected rearwardly from the machine onto the ground.

Automatic bale ejection drive override means

In a crop roll forming machine having a reversibly rotatable bale forming means there is provided an improved drive means with tensioning means movably affixed to the frame for cooperative interaction with the drive means and the bale forming means to selectively cause the bale forming means to cease being driven in a first direction and cause it to be driven in an opposing second direction when the tensioning means is moved to a predetermined position so that a completed crop roll is ejected rearwardly from the machine onto the ground.

A crop harvesting machine has a crop harvesting header, a mobile frame and improved header stabilizing system. The frame is adapted to move across a field in a forward direction and includes upper frame structure extending transversely to the forward direction and a lower wheel frame assembly. The assembly includes a transverse cylindrical member being rotatably mounted to and supporting the upper frame structure. Lift means is provided, being actuatable for moving the lower assembly, and thereby rotating the cylindrical member thereof, relative to the upper frame structure to effectuate raising of the upper frame structure and the cylindrical member relative to the field. A header suspension and lift means includes upper means pivotally interconnecting an upper portion of the header with the upper frame structure and lower elongated means pivotally interconnecting a lower portion of the header with the cylindrical member of the wheel frame assembly. The lower means has a portion which projects rearwardly of the pivotal connection of the lower means with the cylindrical member and underlies the member so as to be engaged by the latter to effect lifting of the header upwardly by the lower means upon rotation of the cylindrical member when the lift means is actuated so as to effectuate raising of the upper frame structure and the cylindrical member relative to the field. A telescoping link extends between and pivotally interconnects the central portion of the cylindrical member and the lower central portion of the header to stabilize the header against excessive lateral movement. The telescoping link may also limit the upper and lower position of the header.

A crop harvesting machine includes a mobile frame, a header movably suspended from the frame, a pair of upper and lower conditioner rolls rotatably mounted on the frame rearwardly of the header, and drive means for operating the conditioner rolls and the cutterbar and reel of the header. The drive means includes a gearbox assembly mounted on the frame and having rotary input drive transmission means and a transversely extending rotary output shaft drivingly coupled to the input means. An upper telescopible shaft articulately intercouples one end of the output shaft with the upper roll for rotatably driving the latter which accommodating movement thereof relative to the lower roll. Gear means is drivingly coupled between an opposite end of the output shaft and lower transversely extending shaft means which, in turn, is drivingly intercoupled to the lower roll, such that the lower roll is rotatably driven in a direction opposite to that of the upper roll. Drive mechanism for operating the cutterbar and reel, being located on the side of the header adjacent the gearbox assembly, is intercoupled to the opposite end of the gearbox assembly output shaft by drive transmission means which includes a forward telescopible shaft which provides rotary power to the header drive mechanism while accommodating movement of the header relative to the mobile frame.
