Abstract
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.
