Deflector door for accessing a sieve of a combine harvester having a seed mill

An agricultural harvester comprising:

• a straw hood having a hollow interior space that receives material other than grain (MOG) from a threshing and separating system of the harvester and chaff from a sieve of a cleaning system of the harvester;
• a weed seed mill mounted to a frame of the harvester or the straw hood, the weed seed mill comprising a stator defining a partially-enclosed interior region and an inlet through which a stream of the chaff from the sieve is delivered into the interior region, and a rotor positioned at least partially within the interior region of the stator, the weed seed mill devitalizing weed seeds contained within the chaff;
• and
• an access door that is moveably mounted within the straw hood, the access door being moveable between a lowered operational position and a raised service position,
• wherein, in the lowered operational position, the access door encloses the rotor and constitutes a portion of the stator of the weed seed mill and is arranged to direct the stream of chaff either into or towards the inlet of the weed seed mill, and
• wherein, in the raised service position, a user-accessible passageway is formed from an exterior of the agricultural harvester, through the interior region of the stator and to the sieve such that a user can access the sieve from the exterior of the agricultural harvester.
