Abstract
A crop bagging machine is provided with a movable chassis having adjustable brakes and a grain container having a rear tunnel defining a rear opening. A pliable plastic bag is fit to the tunnel with the bag bottom closing the opening. A bin on the chassis receives grain, e.g., from a truck and an auger transports the grain from the bin to an elevated position in the container that is above the height of the filled bag. The adjustable brakes are set to establish the level of grain pile in the container to cover the opening and thereby fill the bag. The brakes are independently controlled to provide limited steering. An additional embodiment of the invention shows downsizing for reduction in cost and in dimension for compatibility with conventional shipping containers while further providing adjustability in tunnel size to accommodate variation in bag diameter. A further additional embodiment provides for a modified conveyor system for the grain that utilizes air flow. This latter embodiment provides added versatility for use in removing stored grain when storage is no longer desired.
