1. A combine harvester comprising:
a grain tank for storing separated grain, the grain tank having a bottom end, a top end, and a side wall extending between the bottom and top ends, wherein a vertical central axis passes through the tank, and wherein the top end of the side wall is positioned closer to the vertical central axis than the bottom end, and
a grain tank level sensor array for detecting a level of grain in the grain tank, the grain tank level sensor array comprising a plurality of sensors, wherein the grain tank level sensor array extends between the bottom end and the top end of the grain tank,
wherein the sensors are mounted to the side wall and are spaced apart between the bottom end and the top end, wherein a spacing between adjacent sensors of the plurality of sensors mounted to the side wall decreases in a direction towards the top end of the grain tank.
