Patent ID: 8398469

Claim:
An agricultural work machine for performing harvesting operations, comprising: a support structure; a hopper coupled to said support structure, said hopper being configured to store an agricultural product during said harvesting operations; and an unloading system coupled to said support structure, said unloading system being configured to transport said agricultural product received from said hopper to an off-machine location, said unloading system including : a turret configured to facilitate rotation; a telescoping transfer assembly having a proximal end and a distal end, said proximal end being coupled to said turret, said distal end having a discharge chute, said transfer assembly conveying said agricultural product therewithin, said distal end partially enveloping said proximal end thereby twice enclosing said agricultural product where said distal end partially envelopes said proximal end; a positioning system configured to adjust at least one of an elevation, a length and a rotational position of said transfer assembly to position said discharge chute; and a control system coupled to said positioning system, said control system having an operator input device, said control system being configured to automatically locate said discharge chute from a stowed position to a desired unload position of a plurality of preset unload positions upon receiving an operator input via said operator input device, said control system including a controller including a programable processor and a memory; and a position sensing system including: a first sensor communicatively coupled to said controller and located to detect said elevation of said transfer assembly; a second sensor communicatively coupled to said controller and located to detect said length of said transfer assembly; and a third sensor communicatively coupled to said controller and located to detect said rotational position of said transfer assembly.
