One embodiment of the invention relates to an adapter assembly for a towing vehicle having a drawbar hitch for connecting a towed implement having a pull-through swivel hitch assembly to the towing vehicle. The adapter assembly includes a drawbar extension member having a horizontal cross pin, a clamp assembly to secure the drawbar extension member to the drawbar, an adapter frame having a hook to engage the cross pin, and a trunnion pin to couple the adapter frame to the swivel hitch assembly.

Drawbar adapter for pull-through swivel hitch

The instant invention is directed to an implement transporter having an over-the-center latching mechanism that is selectively biased between locked and unlocked positions by the mere movement of a selection arm. Before moving the empty transporter, the latching mechanism is selectively biased in the locking position so that the ramps lock in place when the operator raises them from the light side, the ground-engaging end. To lower the ramps, the latching mechanism is selectively biased to the unlocked position. The weight of the ramp keeps the latch in place until the operator raises the far end of the ramp slightly, taking the load off the latch. The latch is pulled away from the ramp by the over-the-center mechanism and the ramp can be lowered to engage the ground.

Ramp locks for an implement transporter

The instant invention is directed to method and apparatus for securing an implement to a transporter. The transporter has rigid hooks affixed thereto adjacent the platforms upon which the wheels of the implement rest during transport. The implement has horizontally protruding cross pins that rise as the header on the implement is lowered to the transport position. By directing the wheels of the implement onto the transporter, the cross pins are moved into the mouths of the hooks and then, upon lowering of the implement header, the pins are directed into the throats of the hooks, securing the implement to the transporter.

Apparatus for securing an implement to a transporter

A transporter for use in transporting a harvesting machine having a laterally movable tongue is disclosed wherein the transporter has a jack on the forward end thereof to be deployed during the loading process for improved stability. The jack includes components that lock the jack in place when a load is applied to the jack and unlocks the jack when that load is removed, allowing it to pivot rearwardly to a transport position without manual intervention.

Automatic fold-up jack for an implement transporter

A transporter for use in transporting a harvesting machine having a laterally movable tongue is disclosed wherein the transporter has transversely extending loading ramps pivotally connected to the main frame of the transporter to permit the harvester to be elevated from the ground onto the transporter. The force of the loading tractor, acting through the wheels of the implement, causes each ramp to move to the transport position. As the wheels of the implement reach a platform, separate from the ramp, and engage a cross bar on each ramp, they exert a generally horizontal force on the cross bar that causes the ramp to pivot upwardly to the transport position.

Apparatus for raising ramps on an implement transporter

A crop harvesting implement operatively connected to a tractor having a wheeled frame, a draft tongue, a hydraulic cylinder interconnecting the frame and the draft tongue, a hydraulic cylinder interconnecting the frame and the draft tongue, and a hydraulic conduit system containing at least one flexible hose extending from the forward end of the draft tongue to the tractor, is provided with a hydraulic hose support pivotally mounted on the forward end of the draft tongue to support the flexible hoses at a position forward of the draft tongue. The pivoted hose support is mounted in a pivot bracket that is fixed to the forwardmost end of the draft tongue. The pivoted hose support includes a vertical portion defining a generally vertical pivot axis about which the hose support can rotatably move in conjunction with the pivoting motion of the draft tongue relative to the tractor and frame. The pivoted hose support also includes a support portion that projects away from the draft tongue and a hose clamping bracket that fixes the flexible hoses to the pivoted hose support.

Pivoting hydraulic hose support for agricultural implements

A two stage hydraulic tongue swing mechanism and a tongue latch mechanism for controlling and affixing the tongue of a pull type implement while the implement is being laterally transported. The two stage hydraulic tongue swing mechanism comprises a tongue plate attached to the tongue. A free plate is pivotally attached at the tongue pivot and is controlled by a hydraulic cylinder. The tongue plate and free plate are selectively attached to each other by a lateral transport latch. The tongue latch mechanism is partly affixed to the tongue and partly to the trailframe. Attached to the tongue is a tongue handle that controls the position of a tongue pin. The tongue pin is biased into an angled strike plate with a slot on the edge of the trailframe. The tongue pin may be held in a retracted position by a notched lock bar.

Tongue latch mechanism

A movable unloading auger is automatically latched and unlatched with respect to a support member by connecting a lifting winch and cable to a movable latch arm attached to the auger, thus advantageously permitting hands-off latching and unlatching operations. A guide member includes a slot and the latch arm extends through the slot and terminates adjacent a latch arm receiver.

Automatic latch for unloading auger

Remote control of unloading augers on agricultural grinder-mixers is accomplished by hydraulic motors arranged to adjust the height of the remote end of the auger and to rotate its position in the horizontal plane. These motors are each controlled by solenoid operated valves in the hydraulic system and the valves are operated by sets of electrical controls located in the tractor cab and in proximity to the unloading auger.
