Abstract

A windrower with a header has a conveying medium with first and second portions connected with a pivot joint and moveable across a plurality of rollers configured to receive crop material from the header and direct the crop material to a side of the windrower to form a windrow on the ground to the side of the windrower. In an operational position and with the frame selected to one of the predetermined angular adjustments, the conveying medium discharges the harvested crop material at an angle of trajectory determined by the selected angular positon of the second portion. The windrower harvests crop with the header, receives the mowed crop on the conveyor system, adjusts a rate at which the mowed crop is discharged from the conveyor system, and adjusts an angle of trajectory at which the mowed crop is discharged from the conveyor system.

First claim

At least the following is claimed:

1. A method of operating a windrower with a header coupled thereto, the method comprising:
mowing crop with a header configured to harvest crop material as the windrower advances along a field and discharge the harvested crop in a rearwardly directed stream;
receiving the mowed crop on a conveyor system having a frame coupled to a chassis of the windrower and a moving conveying medium, the frame comprising a first section and a second section with a pivot joint in between said first and second sections, wherein at least one roller is coupled to the first section and at least one roller is coupled to the second section for movement of the conveying medium relative the frame;
moving the frame relative the chassis with a structural assembly between a non-operational, raised position in which the stream of crop material is directed onto the ground under the conveying medium and an operational, lowered position in which the crop material is received onto the conveying medium which directs the crop material to a side of the windrower to form a windrow on the ground to the side of the windrower; and
adjusting an angle of trajectory at which the mowed crop is discharged from the conveyor system with an actuable device by moving the second section relative to the first section about the pivot joint, such that the first section of the conveying medium is oriented at an angle different than an angle of the second section of the conveying medium, wherein in the operational position and with the frame selected to one of the predetermined angular adjustments, the conveying medium discharges the harvested crop material at an angle of trajectory determined by the selected angular positon of the second portion such that the angle of trajectory of crop material leaving the conveying medium relative the ground is different than an angle of movement of crop material on the first section of the conveying medium relative the ground.

2. The method of claim 1 further comprising adjusting a rate at which the mowed crop is discharged from the conveyor system by adjusting the speed that the conveying medium moves relative the frame.

3. The method of claim 1 ,
wherein adjusting the angle of trajectory comprises adjusting an angle formed between the first and second sections.
