1. A harvesting machine comprising
a guide mechanism adapted to direct a flow of crop residue from a threshing mechanism along three paths corresponding with three respective processing modes, the guide mechanism comprising:
a first deflection door supported on a first pivot shaft and fitted with a first crank arm and a second deflection door supported on a second pivot shaft fitted with a second crank arm, both deflection doors movable between respective first end positions and second end positions,an actuator, at its first end coupled to the first crank arm and at its second end to the second crank arm, and being arranged to vary the distance between its ends; and a first resilient element, coupled to the first crank arm such that when contracting the actuator in the first processing mode, the first resilient element exerts a force on the first deflection door in order to hold the first deflection door in its first end position and the second deflection door is brought to its second end position, wherein in the first processing mode, both deflection doors are in their first end position; in the second processing mode, the first deflection door is in its first position and the second deflection door is in its second end position; and in the third processing mode, both deflection doors (96, 94) are in their second end position; wherein when contracting the actuator in the second processing mode, the actuator overcomes the force of the first resilient element in order to bring the first deflection door to its second end position while keeping the second deflection door in its second end position. |
