FIELD: agriculture; machine building.
SUBSTANCE: group of inventions relates to agricultural harvesting machines. Double ended extendable driveshaft comprises first and second shaft portions, first and second shaft couplers, first and second rotary hydraulic couplers, first and second bearings and an actuator. First coupler is attached to the distal end of the first shaft portion, and the first rotary hydraulic coupler is rotatably supported at the proximal end of its first portion. Second coupler is attached to the distal end of the second shaft portion and the second rotary hydraulic coupler is rotatably supported at the proximal end of its second portion. First and second bearings support the first and second rotary hydraulic couplers, respectively, on the first and second shaft portions, respectively. Actuator is connected to the first and second rotary hydraulic couplers for extending and retracting the first shaft portion relative to the second shaft portion.
EFFECT: group of inventions provides connection and detachment of harvesting attachments from agricultural harvesters.
