摘要：
A combine (12) including a frame (12), power unit (32) and a crop gathering and processing device (18, 20, 24, 26). A grain tank (28) is mounted on the frame (12). An elongated closed end tube (74) is vertically oriented within the grain tank (28) and has a plurality of uniformly spaced openings (76) along its length. A pneumatic pressure supply (86) pressurizes the interior of the tube (74). A pressure sensor (84) senses the interior pressure of the elongated tube (74), so that grain building up therein selectively covers the plurality of openings (76) to cause a proportionate increase in air pressure.
