Abstract: A grain bin is provided with a pipe extending beneath the perforated floor through which drying air passes upwardly. A tool extends through the pipe to the central grain outlet opening in the floor. The tool includes a cutting or grinding head which can be rotated from outside the bin so as to break up grain blockages above the outlet opening. A cap may be provided on the inner end of the pipe to preclude grain from entering the pipe.

Abstract: An improved corn head includes a reel device that prevents debris build-up in front of a feederhouse. The reel device includes support arms, a crossbar between the support arms, and a number of radial bars extending from the crossbar. The reel device has a number of adjustments to optimally position the radial bars for removing debris. The reel device rotates to reduce debris build-up in the feederhouse during harvesting. The reel device is moveable between operative and inoperative positions from the combine cab using hydraulics.
