摘要:
A method of controlling a multiengine harvester including the steps of operating the harvester in a first mode, operating the harvester in a second mode, and selecting less than all of the power absorbing loads to be driven. In the first mode, the harvester is operated using a first engine and a second engine to drive the plurality of power absorbing loads. In the second mode, the harvester is operated with the second engine being uncoupled from all of the power absorbing loads. In the selecting step, less than all of the power absorbing loads are selected to be driven dependent upon the sensed load on the first engine while operating in the second mode. The first engine is incapable of driving all of the power absorbing loads.

An agricultural harvester includes a first power unit which is couplable with a first primary load. The first primary load includes a threshing system load. A second power unit has a threshold power output and is couplable with a second primary load. The second primary load includes a propulsion load. A first motor/generator is mechanically coupled with the first power unit. A second motor/generator is mechanically coupled with the second power unit. The second motor/generator and the first motor/generator are electrically coupled together. At least one electrical processing circuit is coupled with each of the first motor/generator and the second motor/generator. The at least one electrical processing circuit is configured for selectively transferring electrical power from the first motor/generator to the second motor/generator, when the second power unit is at or above the threshold power output.

An agricultural combine has a flexible unloading tube for discharging the contents of a grain tank positioned on the combine. The unloading tube includes first and second tubes connected by a pair of swivel joints on an intermediate tube. The swivel joints are actuated independent of one another by either electrical or hydraulic power to provide a range of motion significantly greater than found in current combines. A series of augers, connected through flexible joints, move grain material through the unloading tube. The double swivel joints enable the unloader to be conveniently located in the combine with a minimum intrusion on the overall volume of the unit.

A steering axle assembly of a work machine such as an agricultural harvester includes telescoping axles and hub assemblies on the telescoping axles, with front and rear hydraulic cylinders for axially and angularly adjusting positions of the wheel hub assemblies, including steering the hubs to angles sufficient to minimize a width of the steering axle assembly for transport.
摘要:
An agricultural work machine having a chassis with an operating direction and a transport system coupled to the chassis. The transport system includes a plurality of wheels including a first wheel and a wheel repositioning system. The wheel repositioning system is operatively connected to the first wheel. The wheel repositioning system is configured to adjust a position of the first wheel in a direction substantially normal to the operating direction while the chassis is moving in the operating direction.

An unloader for an agricultural harvester includes a telescopic belted conveyor that can be extended to opposite sides of the harvester. The conveyor can be operated at any selected elevation between a minimum elevation and a maximum elevation and at any extended length between a minimum extended length and a maximum extended length for the conveyor.

A grain tank on a crop harvester includes a belted conveyor floor for moving grain in the grain tank toward an opening through which the grain tank is emptied.
摘要:
A conveyor is mounted on a tractor and extends from a hopper at the front of the tractor to an outlet behind the tractor. An agricultural harvester unloading system is operated to deposit grain from the harvester into the hopper of the conveyor. The conveyor is operated to transfer the grain into a cart pulled by the tractor.
摘要:
The invention is directed to an agricultural work machine for performing harvesting operations. The agricultural work machine includes a support structure. An unloading system is coupled to the support structure and is configured to transport an agricultural product received from a hopper to an off-machine location. The unloading system includes a transfer assembly having a discharge chute. A positioning system is configured to adjust at least one of an elevation, a length and a rotational position of the transfer assembly to position the discharge chute. A control system is configured to automatically locate the discharge chute from a stowed position to a desired unload position of a plurality of preset unload positions upon receiving an operator input via an operator input device.
