A pressurized air cleaning system is provided for a harvesting apparatus having a grain tank for holding harvested crop. The cleaning system can include an air manifold and tubing network for receiving pressurized air and distributing the pressurized air to an outlet port near to the grain tank of the harvesting apparatus. The outlet port is located and configured for connecting a short portable air cleaning hose and wand to be wielded by an operator to clean the grain tank. The air manifold and tubing network can also include an outlet port near to the header, and/or next to the straw chopper, both accessible from grade level. The cleaning system can include air cleaning nozzles, fixed in position on the harvesting apparatus and connected to the network, the nozzles directing air streams onto hard-to-access areas of the harvesting apparatus. The nozzles can be located inside the grain compartment along the horizontal augers and in the unloader tube.

Combine air system for cleanout

An auxiliary rotary drive for at least one auger that in normal operation is rotatable to transport grain from a grain tank of a harvesting apparatus. The auxiliary rotary drive is configured to rotate the at least one auger during cleanout to assist air nozzles or other means to remove residual grain or residue from the harvesting apparatus. The auxiliary rotary drive can be arranged to transfer power to the auger via a clutch arrangement arranged between the auxiliary rotary drive and the auger. The auxiliary rotary drive turns the auger at a speed slower than a normal operating speed of the auger.
